云南省国土空间“三生”功能变化及耦合协调特征

The changes and coupling coordination characteristics of “production-living-ecological” function of geographical space in Yunnan province

为反映云南省国土空间"三生"(生产、生活、生态)功能发展现状及协调水平,构建评价指标体系,采用熵值法构建综合评价模型,引入耦合协调度模型和变异系数,分析2007—2017年云南省"三生"功能协调特征。结果表明,"三生"功能逐步加强,生产、生活功能表现为较明显的"中心—外围"结构,由于德宏州近年来外贸发展速度较快,其生产功能表现也较突出;生态功能强于生产、生活功能,空间上表现为西部较高,东部较低。"三生"功能耦合协调度逐渐提高且州市间差距小幅减小,2007—2012年间耦合协调度年平均增长率高于2012—2017年。"三生"功能整体处于轻度失调到初级协调阶段,协调度空间布局呈现出较明显的"中心—外围"结构和"总体失衡、局部均衡"特点。

In order to reflect the present situation and coordination level of"production-living-ecological"function of geographical space in Yunnan province,an evaluation index system was constructed,and a comprehensive evaluation model was constructed by using entropy method.The coupling coordination degree model and coefficient of variation were used to analyze the functional coupling coordination characteristics of"production-living-ecological"function in Yunnan province from 2007 to 2017.The results showed that,"production-living-ecological"function was gradually strengthened,and the function of production and life showed a more obvious"center-periphery"structure.Because Dehong’s foreign trade had developed rapidly in recent years,its production function was also more prominent;The ecological function was stronger than the production and life function,which was higher in the west and lower in the east.The functional coupling coordination degree of"production-living-ecological"function gradually increased and the gap between cities decreased slightly,and the average annual growth rate of coupling coordination degree from 2007 to 2012 was higher than that from 2012 to 2017.The overall"production-living-ecological"function was in the stage of mild imbalance to primary coordination,and the spatial layout of coordination degree showed obvious characteristics of"center-periphery"structure and"overall imbalance and local equilibrium".
