- Abstract:
-
The past 30 years was the period when the economy grew continually, also the period when the built-up area expanded dramatically. The spatio-temporal pattern of construction land reflected the extension, intensity and frequency of the regional human intervention and affects the process of ecological systems. The overlay of the construction land maps for two adjacent years was used to generate the sprawl categories map. The main three sprawl categories named infilling sprawl, edge-expansion sprawl and outlying sprawl were calculated and analyzed about their distribution and the change over the study years in different counties. Population, economy and policy played an important role in the built-up area number and its expansion types. The alternation of the dominative built-up area expansion types, the outlying sprawl in the beginning period and the infilling sprawl in the later period, indicated the enhancement of land saving and intensive use level in Shenzhen City.
