Abstract

The Kuye River is located in the ‘ji’ bay in the middle reaches of the Yellow River.It is an important water supply section of the Yellow River.The quality of its habitat is related to the ecological security and people's well-being of the basin.Based on GIS technology,InVEST model and linear regression analysis method were used to reveal the spatial and temporal evolution characteristics of land use and habitat quality in Kuye River Basin from 2000 to 2020.The main driving factors of habitat quality change in Kuye River Basin were further explored.The results showed that :1)In 2020,the grassland area of Kuye River Basin decreased by 6.60 % compared with that in 2000,and the forest land area increased by 35.05 % compared with that in 2000.2)From 2000 to 2020,the Kuye River Basin was dominated by areas of medium and high habitat quality.The overall habitat quality was improved,and the habitat quality was reduced in some areas.3)From 2000 to 2020,the total output value of the secondary industry,the total industrial output value,the total population at the end of the year,the landscape separation index and the habitat quality index showed a significant negative correlation.It can be seen that the industrial development and human activities in the Kuye River Basin have a very significant impact on the decline of habitat quality in the study area.

Key words： habitat quality; land use change; InVEST model; Kuye river basin
