| 通过构建基于熵权法的土地生态安全与经济发展评价指标体系，采用耦合协调度模型
对揭阳市2010 — 2018年土地生态安全和经济发展的耦合度、协调度进行综合测算，并分析耦合协

| 英文摘要: |
| By constructing the evaluation index system of land ecological security and economic development based on en⁃
tropy weight method, the coupling degree and coupling coordination degree model of land ecological security and economic
development in Jieyang city from 2010 to 2018 were comprehensively calculated, and the reasons and dynamic mechanism
of coupling coordination change were analyzed. The results showed that the land ecological security index and economic de⁃
velopment index and coupling coordination degree of land ecological security and economic development of Jieyang city
had an upward trend on the whole and the coupling coordination type changed from mild imbalance to weak coordination.
The land ecological security index of Jieyang city decreased from 2010 to 2013, and other intervals had an upward trend.
The index of economic development increased rapidly from 2015 to 2018 and reached the peak value of 0.565 9 in 2018.
The coupling degree of land ecological security and economic development reached the maximum value of 0.581 2 in 2015,
then decreased, and the coupling effect changed from strong to weak. The coupling coordination degree fluctuated signifi⁃
cantly from 2015 to 2018, and the interaction between land ecological security and economic development intensified. The results can provide reference for maintaining the land ecological security and promoting the healthy development of urban
economy in Jieyang city. |
