Post-disaster reconstruction is a topic of global concern, and traditional villages have special heritage attributes and need to face more requirements and obstacles in post-disaster reconstruction. This paper summarizes four concepts based on the research on post-disaster reconstruction both domestically and internationally, as well as the recover...
Since COVID-19, people have suffered tremendous impacts in all aspects of their lives and work, with subtle changes in their environment preferences. The rural areas, with their natural green space, low density, and leisurely habitat, have played an important role after the pandemic and are widely favored by people. Research on rural environments a...
Introduction
Traditional villages are precious historical and cultural heritage sites. The selection of post-earthquake recovery and reconstruction (PERR) mode directly affects the village cultural heritage protection and the development direction of post-disaster reconstruction. A scientific and comprehensive feasibility evaluation for selecting t...
The Da-Xiao Liangshan mountains are critical ecological function areas and essential ecological barriers in the upper reaches of the Yangtze River in China. This study selected a total of six periods of land use land cover (LULC) data from 1995 to 2020, to estimate the ecosystem service value (ESV) and analyzed its spatiotemporal evolution and topo...
Scientific understanding of urban ecosystem service value (ESV) is fundamental to building an urban ecological landscape pattern and improving urban environmental quality. The equivalent factor method (EFM) is widely used in evaluating ESV for natural ecosystems. In this study, using the EFM and sensitivity analysis, our research explored the space...
The quality of the environment should be measured by the satisfaction of the public and guided by the issues of public concern. With the development of the internet, social media as the main platform for people to exchange information has become a data source for planning and management analysis. Nowadays, the rural catering industry is becoming in...
Identifying the ecological vulnerability of the sensitive and fragile ecosystem of the Ya’an-Qamdo section along the southern route of the Sichuan-Tibet transport corridor is of paramount importance to reduce environmental damage resulting from infrastructure construction. This paper divided the Ya’an-Qamdo transport section into 22 subzones accord...
In order to identify the ecological conditions of Sichuan-Tibet Railway, based on the vulnerability evaluation framework of “exposure-sensitivity-adaptation”, this paper selects 20 evaluation indexes including temperature, precipitation, snowfall, herb coverage, total number of plant species, population density and per capita GDP, and establishes a...

... Throughout the development process, prioritizing ecological protection, judicious resource utilization, and industrial structure optimization is crucial. Scholars have further delved into the development of these ecosystems, examining various models, strategies, and policy suggestions [6,7]. Ecosystem restoration involves actions like ecological and vegetation restoration, and soil enhancement to return the ecosystem to its near-natural state. ...

... Changes in land use or land cover can lead to environmental degradation and impact ecosystem services, contributing to global environmental challenges (Bajocco et al., 2012;Li et al., 2009;Sylla et al., 2012). In general, changes in land cover due to human activities will affect the value of ecosystem services (Li et al., 2023). ...

... According to multiple studies, the traditional rural landscape, with its historical and cultural value and beauty, gives rural areas uniqueness, which in turn influences the choice of travel destinations (Carpio et al. 2008). Customers in rural areas often prefer to experience natural landscapes (Yang et al. 2022). Factors such as quality and facilities, image and atmosphere, and scenic elements influence consumer satisfaction with rural village restaurants (Yang and Luo 2021). ...

... The area is located in Ya'an, where topographic rainfall is generated due to the steep rise in altitude [53]. A large amount of precipitation and steep terrain cause soil erosion, and the area is not suitable for ecological protection [54]. Due to the influence of precipitation, LGR, SVM, and MLP have inaccurate prediction results in the northwest of CY. service functions. ...
... Sewage is a major source of pollution during construction. Based on the environmental management experience of the Qinghai-Tibet Railway construction (Bao & Qiu, 2021;Ma et al., 2012) and the requirements of the national standard (Discharge Standard of Pollutants for Municipal Wastewater treatment plant GB 18,918-2002), we divide the indicator pollutant characteristics (B3) into five sub-indicators that influence the classification of pollution source treatment level: sewage suspended (C5), organic matter Vol.: (0123456789) (C6), number of coliforms (C7), ammoniacal nitrogen content (C8), and heavy metal content (C9). We then select the main influencing factors on the classification of pollution source treatment level and build a hierarchical structure model, as shown in Fig. 2. Through the analysis of factor weights, we explore the relationship between factors and the degree of influence on pollution source treatment. ...
