摘要
基于多因素综合评价法对环长株潭城市群8个城市的土地集约利用水平与经济高质量发展水平进行了评价,在此基础上采用耦合协调度模型、相对发展度模型探讨二者耦合协调关系的时空演变特征,并引入障碍度模型分析障碍因子。结果表明:(1)研究期内各市的土地集约利用水平及经济高质量发展水平均呈上升趋势,但各市之间发展差距不断扩大;(2)城市群土地集约利用与经济高质量发展耦合协调性趋向优化,发展状态由失调衰退阶段进入基本协调阶段,且同步发展型城市数量不断增加,两大子系统明显得到改善;(3)人均建设用地面积、人均旅游外汇收入、每万人国际互联网户数、货物进出口总额占GDP比重是阻碍城市群土地利用与经济发展协调性的主要障碍因素。
This paper evaluated the levels of intensive land utilization and high-quality economic development of eight cities in urban agglomerations around Changsha-Zhuzhou-Xiangtan based on the multi-factor comprehensive evaluation method.On this basis,the coupled coordination degree model and relative development degree model were used to explore the temporal and spatial evolution characteristics of the coupled coordination relationship between them,and the obstacle degree model was introduced to analyze the obstacle factors.The results show that:(1)during the research period,the levels of intensive land utilization and high-quality economic development in each city show an upward trend,but the development gap between cities continues to widen;(2)the coupled coordination between intensive land utilization and high-quality economic development in the urban agglomerations tends to be optimized,and the development status has entered a basic coordination stage from the stage of imbalance and decline;the number of cities with synchronous development is constantly increasing,and the two major subsystems have significantly improved;(3)the area of built-up land per capita,foreign exchange income from tourism per capita,the number of households with international Internet per 10000 people,and the total amount of import and export of goods as a percentage of GDP are the main obstacles to the coordination of land utilization and economic development in urban agglomerations.
