Study on the Ecological Environmental Effect and Driving Force of Land Use Change Based on the GIS and CLUE-S Model

摘要

The unreasonable land use is the main reason caused the deterioration of ecological environment. This paper developed a method to explore the eco-environmental effects of land use change by linking CLUE-S model and eco-environment quality index. The results show, the eco-environment quality were improved in Miyun during the period from 1991 to 2006, due increased area in open forest and forest, but would be deteriorated in 2021 if the current land use trend would be followed. However, eco-environment quality could be improved in 2021, if land pattern optimization measures, including riparian buffer zone construction (riparian buffered by forest), conversion of cropland to forest while the slope greater than 25°, reforestation on bare land, could be applied. It was indicated the proposed optimized land use pattern is essential for the improvement of regional eco-environment quality.
