Published: April 10, 2025

Land use change is a key factor affecting habitat quality. To reveal the impacts of urban land changes on quality, this paper uses city Zhongwei, China, as case study. Based data from 1980, 2000 and 2020, PLUS-InVEST coupled model was used to predict assess quality Zhongwei. The results revealed that 1980 areas construction woodland increased by 312.78 127.36 km2, respectively, whereas watershed, grassland, unused decreased 89.86, 666.36, 21.49 respectively. with high low values 25.42% 9.70%, relatively medium 14.81% 7.13%, main factors influencing expansion were precipitation, temperature, population distance government facilities. Other remained largely unchanged. predicted study area in 2040 compared under different development scenarios. A comparison highest value lowest degree degradation possible ecological protection scenario. Although afforestation desertification control projects Zhongwei have proven successful increasing improving their restoration measures not yet completely counteracted adverse effects ongoing urbanization industrialization resulting persistent decline overall

This study, guided by the concept hat “lucid waters and lush mountains are invaluable assets”, focuses on explicating ecological vulnerability characteristics of Nanpan Beipan River Basins, a typical karst river basin in Guizhou Province. In this article, value equivalent table was built to calculate ecosystem service (ESV) within from 2000 2020. The patch landscape urban simulation model (PLUS) improved forecast changes under four scenarios future.
