... During the process of rapid urbanization, wetland resources in China have been excessively exploited and encroached upon [9], leading to a significant degradation of ecosystem services. Pressing issues, such as fragmented wetland patches, reduced freshwater storage, and diminished flood regulation capacity, have emerged [10], rendering wetlands incapable of meeting the requirements for sustainable urban development [11]. ...
Wetlands form a crucial component of ecosystems, and wetland restoration serves as an effective strategy for promoting sustainable urban development. Spatial support is essential for wetland restoration, meaning that research on wetland spatial planning is of considerable importance. Existing studies on wetland spatial planning primarily focus on the analysis of wetland spatial distribution characteristics, with limited exploration of wetland spatial relationships. This paper aims to explore the potential of utilizing both spatial distribution characteristics and spatial relationships to identify wetland spatial issues, thereby facilitating the formulation of wetland spatial planning strategies. Using Tianjin City as a case study, this research applies nearest neighbor analysis, the geographic concentration index, the Gini index, and kernel density analysis to identify the spatial distribution characteristics of wetlands in Tianjin. Additionally, spatial autocorrelation analysis and connectivity analysis are employed to identify the interrelationships among wetlands in Tianjin. Based on the results derived from the analysis of spatial distribution characteristics and spatial relationships, wetland spatial planning strategies are proposed. The effectiveness of these strategies is validated using methods that consider both spatial distribution characteristics and spatial relationships. The findings reveal that, although wetlands in Tianjin are widely distributed, large wetland patches are primarily concentrated in areas with abundant water resources, while the six districts within the city have few or no large patches of wetlands. The spatial distribution of wetlands is highly uneven, exhibiting patterns of high–high aggregation and low–low aggregation. The number of connecting paths between wetland patches is relatively low, indicating a generally low overall connectivity. While medium-sized and larger wetland patches maintain the connectivity of existing wetlands in Tianjin, small wetlands that serve as stepping stones are lacking. Following the implementation of planning strategies, there would be an increase in the wetland area in Tianjin, accompanied by significant improvements in the spatial distribution pattern and spatial relationships of the wetlands.
... The water network connection was a useful and critical measure for water resource allocation, water ecological restoration, and water quality improvement Yu et al., 2020). It was conducive to increasing water flow, improving hydrodynamic circulation and self-purification capacity, and preventing pollutant accumulation in the lake (Cui et al., 2009;Wang et al., 2016). Through the completely water exchange between the lake and the Yangtze River, the water quality of Sha Lake had been improved (Luo et al., 2021). ...
Urban development has positive and negative effects on the evolution of enclosed lake water quality. This study aims to quantitatively analyze the water quality evolution of a typical urban lake, the Sha Lake, in the process of urban development. The land use degree comprehensive index (I) was calculated to reveal the level of urban development; water quality index (Smid) and eutrophication index (Tmid) were used to evaluate the water quality changes by fuzzy comprehensive-quantifying assessment (FCQA) method. The urban construction process and the water quality changes in 2000–2018 in the Sha Lake Basin were divided into three stages: (1) in 2000–2006, with the slow urban development, water quality remained stable and the degree of eutrophication improved slightly; (2) in 2007–2009, I increased rapidly to reach 300, Smid and Tmid increased from 90.62 to 92.83 and 75.06 to 87.52, respectively. Water quality deteriorated because of the failure to implement environmental protection measures in time; (3) in 2010–2018, although urban development reached a high level (I > 300), the water network connection project, dredging project, exogenous pollutant control, and sewage pipe network renovation since 2009 were critical measures to improve water quality for a long time. Due to the lag effect on improving water quality, the implementation of environmental protection measures should be synchronized with or even before urban construction. The research results can provide a scientific basis for the urban lake water environment protection in the process of urban development.
... The Wuhan urban agglomeration (WUA), which was approved as a comprehensive reform pilot area in 2007, is the core region of economic development in Central China . During recent decades, the WUA has experienced rapid economic development and faced many eco-environmental problems, such as reclamation of lakes, water pollution and cropland encroachment Wang et al., 2016). To promote the delivery of the SDGs in the WUA, we aimed to develop a hybrid model by coupling a spatial allocation model and the equivalent coefficients table method, and explored the future spatio-temporal change characteristics of land use and the ESV. ...
Terrestrial ecosystem services can offer various kinds of benefits for human life and production and play a critical role in the attainment of the Sustainable Development Goals (SDGs). The quantitative evaluation and spatial mapping of ecosystem services can offer useful information and knowledge for the natural resource protection and implementation of the SDGs. In our study, we investigated the ecosystem service value (ESV) from 2015 to 2035 under three alternative scenarios and examined their contributions to the SDGs in the Wuhan urban agglomeration. The spatial allocation algorithm, which integrates random forest regression and the CLUE-S model, was used to project the spatial distribution of land use from 2015-2035 under the natural increase scenario (NIS), economic development scenario (EDS), and ecological protection scenario (EPS). These simulation results generated the indicators of SDG 15.1.1 and 15.3.1. Then, the equivalent coefficients table method was leveraged to evaluate the ESV changes that resulted from land use changes, which could directly contribute to the SDG 15.9 target. The results indicated that the EDS had the lowest value for SDG 15.1.1 and the highest value for SDG 15.3.1, while the EPS had the highest value for SDG 15.1.1 and a moderate value for SDG 15.3.1. The total ESV increased from 2015-2035 under NIS and EPS, with gains of 5.46 and 8.86 billion CNY, respectively. In contrast, the total ESV decreased under EDS, with a loss of 0.33 billion CNY. In addition, it was found that the land degradation corresponding to SDG 15.3.1 would result in ESV losses of 8.40, 12.24, and 4.88 billion CNY under NIS, EDS, and EPS, respectively. This research developed an integrated framework to assess the potential impacts of land use changes on the ESV under three future scenarios and could offer foundational knowledge for urban development and realization of the SDGs.

Entrepreneurial motivations and networks in creative tourism place-making are examined using a descriptive case study approach. In Dali creative village in Wuhan, China, place-making was primarily driven by creative artisans and entrepreneurs from elsewhere. Actors’ social networks were primarily personal and lacked business cooperation, indicating the organic nature of place-making. The diversity of individual resources, capabilities and expectations of entrepreneurs has led to the lack of a consistent vision of place-making. Tension over ownership of place-making appeared between residential and nonresidential groups. Creative tourism entrepreneurs need to adapt to the restructuring forces of tourism and commercialization and adjust social networks as place-making stages evolve. This research contributes to the understanding of social networks and their roles in place-making, with implications for creative tourism planning and management.

Relevant studies have revealed that the study region suffers from land reclamation, environmental pollution and resource waste Wang et al., 2016). Therefore, taking the WUA as a case study, this research predicts the urban wetland dynamics under three scenarios, and explore the spatiotemporal characteristics of wetland in the future. ...
Wetlands are one of the most productive ecosystems and play an important role in supporting a wide range of biodiversity and providing various kinds of ecosystem services. Rapid urbanization and climate change, however, have resulted in the disappearance of large amounts of wetlands. In this research, we developed a spatial allocation model by coupling random forest regression and the CLUE-S algorithm to simulate the spatial dynamics of wetlands in the Wuhan Urban Agglomeration. Then, the calibrated model was used to predict the wetland distributions from 2015 to 2040 under three scenarios, i.e. natural increase scenario (NIS), economic development scenario (EDS), and wetland protection scenario (WPS). The results showed that: (1) the natural wetlands exhibit a slight decreased trend under EDS, and a slight increased trend under WPS. But regardless of scenarios, the natural wetlands will suffer from degradation in densely built-up areas during 2015–2040; (2) The ponds will clearly expand under all scenarios, and most of their expansion distribute in Xiantao city; (3) The paddy will continue to degradation under three scenarios, and the area decreases most under EDS with value of 2866.94 km². Most of the paddy degradation are located in Wuhan, Xiantao and Ezhou city. The proposed framework offered an effective tool to explore the urban wetland dynamics in the future, and revealed wetland distribution under different scenarios, which could provide support for the protection of urban wetlands and sustainable future develop in the Wuhan Urban Agglomeration.

... Zheng et al. addressed how the water storage capacity of natural water bodies, the infiltration capacity of permeable pavement, and the rainwater discharge capacity of the river system may help in mitigating urban flooding [22]. Meanwhile, measures such as conserving urban lakes [23] and improving the status of the river-lake system, social system, and environmental system, will increase the natural rainwater's storage capacity, and finally improve the urban flood-resistance capacity [24]. ...
In 2016, 192 cities, including Wuhan, Nanjing, and Jiujiang, suffered from severe flooding, which raised social and government concerns in China. This paper proposes a method based on the underlying surface to estimate the urban flood-carrying capacity. First, water is extended into the underlying surface vegetation-impervious surface-soil (VIS) model to form the vegetation-impervious surface-soil and water (VIS-W) model. Second, the watershed is delimitated using a digital elevation model (DEM). Third, the natural water system’s storage capacity, including rivers, lakes, and puddles, is estimated. Using the rainfall–runoff hydrology model and the VIS-W model, the storing ability, the receiving ability, the discharge potential, and the emergency of pumping outward are assessed to derive the final flood-carrying capacity. Finally, the result is compared with data on the waterlogging points collected in July 2016 during a flood and waterlogging event in Wuhan. It is found that 84% of waterlogging points are located in the “weak” or “normal” areas, and 16% are located in the “strong” areas. Additionally, 99% of total waterlogging points are located upstream, based on the stream extracted by the DEM. This phenomenon indicates that Wuhan can mitigate flood disasters by fully utilizing the natural water system storage capacity to corporate the city’s drainage schedule.
... Wuhan, located in Central China, is known as the confluence of the Yangtze and Hanshui rivers and the city of over one hundred lakes. Wuhan is the most abundant freshwater storage area in China (Wang et al., 2015). However, many of the lakes were polluted, damaged, and even filled with the rapid urbanization of the past decades, cutting off ecological connections among the water bodies (Chen et al., 2015a;Yang and Ke, 2015). ...
... In 2009, the local government proposed a riverlake and urban compound system, which connects the lakes of the Donghu lake area and imports the river water to replace the lake water in order to restore the ecological environment of the Donghu lake area. The sustainability of this compound system has been improved overall in the past years (Wang et al., 2015). However, these water pollution control actions are less helpful for alleviating the inland flooding caused by the overload storm runoff (Sheng and Nawari, 2016). ...
Population increase and migration from rural areas to urbanized regions have resulted in the formation of gray cities mainly comprised of impervious surfaces. High quantities of stormwater runoff containing pollutants from gray cities cause problems including inland flooding and water pollution. An innovative and evolving response to this global issue is the development of green cities that utilize low impact development (LID) and analogous initiatives. This paper aims to assess LID efforts and relevant governmental policies from a global perspective. It provides a vantage on major evolving LID technologies, where the best policies regarding planning, design, construction, and management are still not well known. The case studies of LID and relevant governmental policies around the world are presented to facilitate future quantitative and qualitative stormwater management in urban regions. This study found that the western and eastern regions around the globe have different driving forces and attitudes regarding implementing LID. These differences are reflected in the name of their LID-like initiatives with varying ramifications. The western regions, such as the United States, pay more attention to restoring water quality, whereas the eastern regions, such as China, prioritize flood prevention and rainwater harvesting. Levying stormwater fees and indirect subsidies by offering a discount are effective for promoting LID to some extent. This paper also provides an in-depth discussion in regard to the latest essence of LID technologies, which magnify their ability to manage stormwater while also providing societal, environmental, hydrological, and aesthetic benefits. Governments should encourage and support the development of green cities by using LID and analogous initiatives.
... However, a decrease in wetland area reduces the available habitat for native fauna and flora [6] and ecosystem functions [7]. During the past few decades, a significant area of estuarine wetlands has disappeared in some large river deltas due to rapid urbanization [8]. The remaining wetlands are suffering from population pressure, water shortage, and pollution, as well as biological invasions, and are becoming increasingly vulnerable [9][10][11]. ...

Understanding wetland changes under urbanization is important for wetland management. In this study, net transition intensity (NTI) and total transition intensity (TTI) are presented to characterize wetland transitions based on spatial data obtained from Landsat satellite images of Pearl River estuary in South China. NTI is commonly used to represent changes in absolute amounts for each class of wetland, while TTI reflects the internal transition activities and amounts. The third index, the urbanization intensity index (UII), is used to investigate the intensity and velocity of urban land expansion at the same time periods. The results show that one-third of the total wetland area was lost from 1979 to 2009 in the study area and seven types of estuarine wetlands were degraded. The basic pattern of wetland transition is from natural wetlands to constructed wetlands and then to urban lands. Intertidal mud and sand and paddy fields were the major natural and constructed wetlands, respectively, transferred to urban lands. The TTI value was generally greater than the NTI value for these wetlands. TTI ≫ NTI is an important indicator for wetland transitions under rapid urban expansion in the Pearl River estuary. Based on the integration of the two indices (NTI and TTI), a protection and management plan framework for the Pearl River estuary wetlands is proposed. This plan emphasizes the key and important zones and their different features, and includes actions that can be implemented in and around natural and constructed wetlands.
