宁夏六盘山连片特困区生态环境与经济发展耦合协调研究

以宁夏六盘山贫困地区为例，建立了耦合协调度评价指标体系，综合运用熵权法、耦合协调度模型以及地理探测器等方法对研究区2006—2016年生态环境与经济发展耦合协调度做出了时空变化分析。结果表明:（1）研究期间，宁夏六盘山生态环境与经济发展耦合度和耦合协调度呈现同步稳定增长的变化态势，生态环境与经济发展耦合度和协调度指数呈现出先减后增的变化趋势，说明生态系统与经济系统之间相互作用程度不断增强，内部协调程度进一步提升。（2）从空间分异来看，耦合协调低值区主要分布在经济发展落后且生态环境质量较差的西北和南部地区，高值区主要分布在经济发展水平、城市化水平较高的行政中心区域，耦合协调度由西北向东南呈现出低—高—低的空间分布格局；耦合协调度高、低值区的分布主要受经济发展水平、城市化水平、资源禀赋等条件的限制。（3）基于地理探测器探测影响耦合协调度空间分异因素的结果可知:人均GDP、GDP增长率、农村人均纯收入、森林覆盖率、建成区绿化覆盖率、人均公园绿地面积、环保投资额占GDP比重、人均牧草地面积和人均水资源量等因子的q值均大于0.9，是影响六盘山区生态环境与经济发展耦合协调度空间分异的主导因素，也是区域经济发展和生态建设过程中应关注的重要因素。

Research on Coupling and Coordination of Ecological Environment and Economic Development in Concentrated Destitute Area of Liupanshan Mountain in Ningxia Autonomous Region

Taking the poverty-stricken areas in Liupanshan Mountain of Ningxia as an example, the evaluation index system of coupling coordination degree was established, and the spatial and temporal changes of the coupling degree of ecological environment and economic development in the study area from 2006 to 2016 were comprehensively applied by entropy weight method, coupling coordination degree model and geographic detector. The analysis and research results show that: (1) during the research period, the degree of coupling and coordination of the ecological environment and economic development of Liupanshan Mountain in Ningxia showed a synchronous and steady growth trend, indicating that the degree of interaction between ecosystems and economic systems was increasing, and the degree of internal coordination was further enhanced; (2) from a perspective of spatial differentiation, the coupling and coordination low-value areas mainly distributed in the northwest and southern regions with poor economic development and poor ecological environment; the high-value areas mainly distributed in the administrative center areas with high economic development level and high urbanization level; the coupling coordination degree showed a low-high-low spatial distribution pattern from northwest to southeast; the distribution of high coordination and low value areas was mainly limited by economic development level, urbanization level and resource endowment; (3) based on the diagnosis of geo-detector, the spatial differentiation factors of coupling coordination degree could be seen that q values of per capita GDP, GDP growth rate, rural per capita net income, forest coverage, green coverage of built-up areas, per capita park green area, environmental protection investment as a percentage of GDP, per capita, pasture area and per capita water resources were greater than 0.9, which were the dominant factors affecting the coupling degree of ecological environment and economic development in Liupanshan Mountain, and also the important factors in the process of regional economic development and ecological construction.
