Health Evaluation and Obstacle Factor Diagnosis of Land Use System in Shaanxi Province From 2011 to 2022
The health evaluation of land use system is closely related to improving the sustainable development level of land use.In this paper,the entropy right TOPSIS model is used;coordination degree model and obstacle degree model are coupled,and 19 indicators from the aspects of structures,function and benefit are selected to e-valuate the dynamic changes of land use system in Shaanxi Province in the past 12 years(from 2011 to 2022).The results show that:① the health level of land use in Shaanxi province has increased year by year from 2011 to 2022,from a medium level in 2011 to a good one in 2022.② The health of structural subsystem showed an up-ward trend from 2011 to 2022,with an average annual increase of 1.96％;the health of functional subsystem in-creased from 2011 to 2022 with an annual increase of 5.69％,and from the poor level in 2011 to the excellent level in 2022;the benefit subsystem showed an upward annual increase of 3.18％and from the moderate level in 2011 to a good level in 2022.(3)From 2011 to 2022,the coupling and coordination between the three subsystems of land use structures,functions and benefits in Shaanxi Province increased year by year,from 0.58(barely coordina-tion)in 2011 to 0.84(good coordination)in 2022.④ The obstacle degree of each subsystem to land use health in Shaanxi Province is structure＞function＞benefit subsystem;from the index level,the GDP,population density,land utilization rate and forest coverage rate are the main obstacle factors for the influence of land use health in Shaanxi Province.The research results can provide a scientific reference for the higher-quality and more sustain-able development in Shaanxi Province.
