Construction of a green infrastructure network for sustainable expansion of mountain cities:A case study of Lincang City,Yunnan Province,China
摘要
Abstract
Constructing a regional green infrastructure(GI)network can alleviate the contradiction between land use and ecological development in the process of rapid urbanization,playing a significant role in future urban planning.This study investigated Lincang City,a typical mountain city in Southwest China.Employing the patch-generating land use simulation(PLUS)model,this study predicted the land use and land cover(LULC)in Lincang City in 2030 under the ecological priority scenario.Furthermore,this study extracted information about the ecological source areas and corridors by integrating the morphological spatial pattern analysis(MSPA),minimum cumulative resistance(MCR)model,and circuit theory.Finally,this study constructed an optimized GI network for 2030 adapted to the sustainable expansion of Lincang City.The results show that from 2020 to 2030,the construction land area in Lincang City is projected to expand by about 23％,while forest land and grassland will decrease by 0.2％ and 1.3％,respectively.The water area is expected to increase by 46.9％ under reasonable management and protection.The core zone of GI landscape elements will represent 56.12％ of the total area,while the edges will make up 21.3％.The spurs,bridging zones,islets,perforations,and circuits will constitute the rest 22.6％.Under the sustainable urban expansion scenario,the GI scale remains overall stable,with a relatively scattered distribution in built-up areas.The optimized GI network will involve 12 ecological source areas and 24 ecological corridors.The GI network of Lincang City in 2030 constructed based on the MSPA-PLUS model strengthens the understanding of the GI network for the sustainable development of a mountain city,adapting to future urban development.This study provides novel insights into the urban planning of mountain cities including Lincang and critical implications for GI protection and regional ecological security maintenance.关键词
