Space-temporal change of land in Shenzhen and its implications for the ecological civilization strategy
With the development of urbanization,Shenzhen has also entered the stage of rapid development of land urbanization.Rapid urbanization not only intensifies the land-use transformation,but also affects the value of ecosystem services.In this context,optimizing the spatial pattern of land urbanization has become the best means to balance economic development and ecosystem.Taking Shenzhen as an example,this paper studies the impact of land use change in Shenzhen from 2000 to 2020 on the value of ecosystem services using remote sensing data and geographic information system methods,revealing the relationship between land use change(LUCC)and ecosystem service value(ESV).The results show:1)The significant increase in the area of construction land in Shenzhen during the study period led to excessive land supply tension;2)The reduction in the area of cultivated land,forest land,and water area resulted in a decrease in the ecosystem service value of Shenzhen;3)The largest changes in ESV were in hydrological regulation and climate regulation;4)Water bodies,cultivated land,forest land,and grassland had the greatest ecological contribution rate to ESV change and are sensitive factors for ecological service changes.
