- Abstract:
-
In order to promote the sustainable use of land in the Xiangjiang River Basin, taking the Xiangjiang River Basin in Hunan Province as the research area, we constructed a land use multifunctionality evaluation index system based on production functions, living functions and ecological functions, and used the improved TOPSIS model to evaluate the multifunctional land use status of the Xiangjiang River Basin in Hunan Province from 2010 to 2018. The obstacle degree model was used to identify obstacle factors affecting the improvement of land use versatility, and then a path to optimize land use versatility was proposed. The results show that:(1)the land use multifunction of Xiangjiang River Basin presented an increasing trend on the whole, in which the production function and living function were strengthening, while the ecological function was weakening; from 2010 to 2018, the land use multifunction value increased from 0.392 5 to 0.574 5, and the degree of land use multifunction experienced a medium to strong process;(2)from 2010 to 2013, PM2.5 concentration, output value of tertiary industry, population density, per capita retail sales of social consumer goods were the main obstacles to land use multi-functional improvement; from 2014 to 2018, ecosystem service value per unit area, rural working population, per capita cultivated land area and habitat abundance index were the main obstacles to land use multi-function improvement;(3)from 2010 to 2018, the restriction of ecological function on the improvement of land use versatility in Xiangjiang River Basin was increasing, while the restriction of production and living function was decreasing. In the future, the Xiangjiang River basin should give priority to the protection of ecological land, strictly protect cultivated land, increase rural working population, so as to promote regional sustainable development.
