城市土地利用与生态文明建设协调发展研究——以成都平原经济区为例

A Research on the Coupling and Coordinated Development of Urban Land Intensive Use and Ecological Civilization Construction—An Example from Chengdu Plain Economic Zone

目的:分析成都平原经济区城市土地集约利用与生态文明建设耦合协调时空演变特征,并预测发展趋势。方法:耦合度、耦合协调度、相对发展度模型与灰色预测模型。结论:(1)2009—2019年成都平原经济区城市土地集约利用水平呈上升趋势,呈“中部高两侧低”特征;(2)生态文明建设水平波动上升,呈“中间低两侧高”特征;(3)两系统耦合协调度依次经历了由濒临失调到勉强协调再到初级协调的演进过程,呈“中间高两侧低”特征;(4)2020—2024年两系统耦合协调度将一直处于初级协调阶段,区域一体化程度进一步提升。

The objective of the research is to analyze the space-time evolution characteristics of the coupling and coordination between urban land intensive use and ecological civilization construction in Chengdu Plain Economic Zone,and predict the development trend.The methods include coupling,coupling co-scheduling,relative development model and grey prediction model.The conclusion can be drawn as follows(1)from 2009 to 2019,the intensive use level of urban land in Chengdu Plain Economic Zone showed an upward trend,with the characteristics of“high in the middle and low on both sides”;(2)the level of ecological civilization construction fluctuates and rises,showing the characteristics of“low in the middle and high on both sides”;(3)the coupling coordination degree of the two systems has gone through the evolution process from the verge of imbalance to the reluctant coordination and then to the primary coordination,showing the characteristics of“high in the middle and low on both sides”;(4)from 2020 to 2024,the coupling and coordination degree of the two systems will always be in the primary coordination stage,and the degree of regional integration will be further improved.
