Abstract
Land use and cover change is an important factor reflecting the resource footprints of the human race. Studies related to land use and cover change with ecosystem services value can provide a good reference for research on human resource footprints. In this study, through the interpretation of remote sensing images of Chengdu from 2000 to 2015, we obtained data on land use and cover change. Based on the analysis of the equivalent factor table for land use and cover change and ecosystem services value, we used the CPI accumulation coefficient and marginal value coefficient to modify the evaluation model of ecosystem services value, thus calculating the value of ecosystem services for Chengdu. The results show that the area under farmland and grassland continued to decrease, while the area covered by forest land, water area, construction land and unused land continued to increase in general. The ecosystem services value of Chengdu increased from 2.86×1010 RMB yuan in 2000 to 5.02×1010 RMB yuan in 2015, indicating a 75.46% increase. From this study, we determined that the development of Chengdu during 2000–2015 is sustainable, with reasonable land use, and will provide an important reference for economic development and land use policy in Chengdu in the future.
