Spatio-temporal Evolution and Prediction of Land Use and Habitat Quality in Chuzhou City Based on PlUS-InVEST Model
Exploring land use patterns and habitat quality under different scenarios is of great significance to promote the sustainable use of regional land resources and maintain ecological security.Based on the land use data of Chuzhou City from 2000 to 2020,the PLUS model,IM model and InVEST model were used to analyze the spatial-temporal evolution characteristics of land use change and habitat quality and to simulate the land use pattern and habitat quality of Chuzhou City under different scenarios in 2030.The results showed that from 2000 to 2020,the construction land of Chuzhou City continued to expand,the cultivated land area gradually de-creased,and the change tendency of land use intensity was obvious.In 2030,under the ecological protection scenario of Chuzhou City,forest and grassland land increased significantly,and the expansion rate of construction land slowed down.In the other three sce-narios,ecological land use decreased,and the urban blue-green spaces shrank.From 2000 to 2020,the overall habitat quality of Chuzhou City showed a downward trend,and the expansion of construction land led to a significant decline in habitat quality in Langya District and its surrounding areas.In 2030,the habitat quality of Chuzhou City was ranked from high to low in four scenariose-cological protection scenario＞cultivated land protection scenario＞natural development scenario＞economic development scenario.The results can provide scientific references for the optimization of ecological patterns and the high-quality development in Chuzhou City.
