摘要
生态文明建设强调要在保护生态环境的前提下实现发展,区域社会经济发展与土地生态安全应保持耦合协调。选取合肥市为研究区,建立社会经济发展与土地生态安全耦合协调评价指标体系,探究两者的耦合协调关系。结果表明,2010—2020年合肥市土地生态安全与社会经济发展先后经历了基本协调、中度协调和高度协调状态,2020年两者耦合协调度值已达到0.9622。2010—2020年合肥市土地生态安全主要障碍因子为化肥使用量、耕地数量、工业固体废弃物产生量等,社会经济发展系统主要障碍因子为在校学生数量、地方财政收入、全社会消费品零售总额等。
The construction of ecological civilization emphasizes the realization of development while protecting the ecological environment,and the coupling and coordination between regional socioeconomic development and land ecological security should be maintained.Select Hefei as the research area to establish an evaluation index system for the coupling and coordination of socio-economic development and land ecological security,and explore the coupling and coordination relationship between the two.The results indicate that from 2010 to 2020,the land ecological security and social economic development in Hefei experienced basic coordination,moderate coordination,and high coordination.The coupling coordination degree value of the two has reached 0.9622 in 2020.The main obstacles to land ecological security in Hefei from 2010 to 2020 were the use of fertilizers,the amount of arable land,and the production of industrial solid waste.The main obstacles to the socio-economic development system were the number of students in school,local fiscal revenue,and the total retail sales of consumer goods in society.
