Shenzhen located in South China has experienced a rapid period of construction land expansion over the past three decades. This paper focuses on the pattern change and the sprawl categories about the construction land integrating remote sensing and geographic information systems (GIS). We analyzed the spatial and temporal patterns of the constructi...

... period 1979-2005, the whole construction land increased continuously and rapidly in Shenzhen, although some sprawl categories decreased and some increased. The construction land expanded least only 37.67km2 during 1985-1990 and expanded most nearly 874.76 km2 during 200-2005. The outlying sprawl was the primary sprawl category in the whole period (Fig.2, Fig.3). Over 60% of the total sprawl was outlying sprawl from 1979 to 2005, while the infilling sprawl was just less than 16%. The outlying sprawl peaked in 1990-1995 while the edge-expansion and infilling peaked in [2000][2001][2002][2003][2004][2005] period. The three categories increased 215.71km2, 132.25 km2, and 526.80 km2 for ...

The planning and management of urban environment require huge amount of information regarding almost all aspects of natural and man-made features of that area. Until lately, such a study could be achieved through days of exhaustive surveys, map generation and tedious calculations. Remote sensing provides huge temporal database for an area and GIS s...
Many municipalities in the US are deploying urban planning approaches to resolve problems caused by urban sprawl, particularly the lack of support for physical activity. Although a variety of perspectives on the relationship between physical activity and built environment exist, many studies have suggested objective and reliable measures of urban f...

... Many studies have already elaborated on the spatial and temporal patterns of urban growth in Shenzhen. For instance, Lv et al. (2009) found outlying growth to be the main growth pattern during 1979 and 2005. Li et al. (2005) described the urban growth from 1978 to 1999 as at first fragmented, then expanded and finally amalgamated. ...
... The spatial distribution of the urban growth patterns in 2011− 2015 seems to be evenly distributed across the city. Lv et al. (2009) also distinguished infilling, edge-expansion, and outlying urban growth at the patch level in Shenzhen. However, their rule to define a patch, i.e. 4-cell neighbourhood rule or 8-cell neighbourhood rule, was not mentioned in the paper. ...
It is essential to understand how urban plans affect urban growth patterns in order to improve current urban planning and management systems. Few studies have been conducted to analyse urban growth patterns of Shenzhen, an international megacity located in southern China, but none of them revealed the relationships between urban planning and urban growth patterns. This study explores the effects of urban master plans on urban growth patterns in different plan periods in Shenzhen. We first quantified the urban growth patterns comparing pixel- and patch-based methods. Three methods resulted in different quantities and spatial characteristics of urban growth. We then explored the relationships between urban growth patterns and urban planning in Shenzhen through multinomial logistic regression models. Across two planning periods, the master plans together with other socio-economic, physical, proximity, accessibility and neighbourhood factors shaped the urban growth patterns of Shenzhen. Out of the master plan elements, planned main roads in the Master Plan of Shenzhen 1996–2010 and the planned built-up zone in the Master Plan of Shenzhen 2010–2020 ha d stronger effects on urban growth patterns but contributed less than most other factors, e.g. distance to ocean. The importance of the other influence factors also varied over time. This changing effect suggests that we need to consider carefully whether driving factors might change in their importance over time when investigating future scenarios of urban land use change. Overall, this approach could also be applied to monitor progress in the paradigm shift towards an integrated urban-rural development in China.
