Abstract

In the 21st century, global urbanization has become an inevitable trend of the development of human society, urban expansion would unavoidably transform ecological land-use such as forest, farmland, grassland, swamps and water area, which have important ecological service functions, into land used for urban construction purpose. Consequently, this will exert great impact on ecosystem in the urban, the regional and even global scopes. In the future rapid urbanization process, it is very important to protect necessary ecological land-use for sustaining well-being of urban ecosystem itself, improving living standards of urban citizens and realizing urban sustainable development. With a case study of Shenzhen, a special economic zone of China, this paper combined ecological conceptual model of landscape with assessment methods for valuation of ecosystem service function, and with the support of GIS technique, established a spatial analysis model for urban minimum ecological land-use. Meanwhile, according to four scenes which reserved ecological land-use respectively by 30%, 40%, 50% and 60%, it analyzed the reasonable spatial distribution of minimum ecological land-use. The outcome demonstrated that the minimum ecological land-use model can extract the type of lands which have important urban ecological service functions.
