The Influence of Land Use Change on Ecological Carrying Capacity in Wuhan Urban Agglomeration

摘要

Obtaining the land use change and ecological carrying capacity change accurately and understanding the specific impact of land use change on biocapacity is of great significance for sustainable development. This study analyzed the influence of land use change on ecological carrying capacity, aimed at providing technical support for regional development planning. Land use change models are adopted to evaluate the dynamic change of land use in Wuhan Urban Agglomeration from 2000 to 2015, whose land use information is extracted from Landsat images. Ecological carrying capacity is calculated with 4 driving factors. The obtained results indicate that the trend of land use degree change is consistent with that of ecological carrying capacity. The relative change rates of different land use types in different cities also affect their biocapacity. We can effectively use the ecological resources, but the demand of human's development for resources is also growing rapidly.
