土地生态安全是生态文明建设的重要组成部分,经济发展是国家富强、社会进步和人民生活水平提升的需要,探究两者的耦合协调关系,有利于统筹经济发展和土地保护。从广东省宏观角度出发,收集2000—2018年的数据,在借鉴文献的基础上,构建土地生态安全与经济发展评价指标体系,然后建立耦合模型测算耦合协调度,分析和探讨经济发展及其各子系统与土地生态安全的耦合协调水平。结果 表明:(1)广东省土地生态安全和经济发展整体呈现上升趋势,耦合程度保持在中度耦合水平,耦合协调状况经历了中度失调—轻度失调—中度失调—轻度失调—勉强协调—基本协调—中度协调的变化,2013年从经济滞后型转变为土地生态滞后型;(2)经济总量、人民生活与土地生态安全的耦合协调水平不断增强,但后者与土地生态安全的耦合协调水平要低,而经济结构与土地生态安全则处于失调状态。研究结果能为广东省经济发展和生态文明建设提供决策依据。

land ecological security is an important part of ecological civilization construction. economic development is the need of national prosperity, societal progress and people's living standards. to explore the coupling and coordination between the two is conducive to overall economic development and land protection. from the macro perspective of guangdong province, the data of 2000—2018 were collected, and on the basis of references, the evaluation index system of land ecological security and economic development was constructed, then the coupling model was established to measure the coupling and coordination, and the coupling and coordination level of economic development and its subsystems and land ecological security were analyzed and discussed. the results were showed as follows. firstly, the overall trend of land ecological security and economic development in guangdong province was on the rise, and the coupling degree remained at a moderate level. the coupling coordination situation had experienced the change of moderate maladjustment-mild maladjustment-mild maladjustment-barely coordination-basic coordination-moderate coordination. in 2013, it changed from the economic lag type to the land ecological lag type. second, the level of coupling and coordination between economic aggregate, people's life and land ecological security had been increasing, but the level of coupling and coordination between the latter and land ecological security were lower, while the economic structure and land ecological security were in a disordered state. these results can provide decision-making basis for economic development and ecological civilization construction of guangdong province.
