新发展理念下土地利用效益的耦合协调关系研究——以南京市为例

A study on the coupling and coordination relationship of land use benefits under the new development concept——Take Nanjing as an example

基于新发展理念,从经济、社会、生态3个层面构建土地利用效益评价指标体系,运用熵值法和耦合协调模型,对南京市2011—2020年的土地利用效益水平和耦合协调状况进行实证分析.研究结果表明:(1)2011—2020年,南京市土地利用经济、社会及生态3方面的效益整体呈现上升趋势,生态效益值在研究期间略有波动,且当前数值较低;(2)土地利用效益间的耦合度基本保持高度耦合状态,耦合协调度则由不协调阶段逐步进入协调发展阶段.根据研究结果提出:进一步优化产业结构,创新开放提高土地经济效益;合理规划土地布局,协调共享社会土地资源;加大生态治理力度,实施农业绿色发展以及均衡土地利用,提升耦合协调程度.

Based on the new development concept,the evaluation index system is constructed from the economic,social and ecological levels,and the entropy method and coupling coordination model are used to empirically analyze the land use benefit level and coupling coordination status in Nanjing from 2011 to 2020.The results show that:(1)From 2011 to 2020,the economic,social and ecological benefits of land use in Nanjing showed an overall upward trend,and the value of ecological benefits fluctuated slightly during the study period,and the current value is low;(2)The coupling degree between land use benefits basically maintains a high coupling state,and the coupling coordination degree gradually enters the coordinated development stage from the uncoordinated stage.According to the research results,it is proposed to further optimize the industrial structure,improve the economic benefits of land innovatively,reasonably plan the land layout,coordinate and share social land resources,strengthen ecological governance,implement green agricultural development and balanced land use,and improve the degree of coupling and coordination.
