生态与经济协调发展水平测度及空间关联分析——以辽宁省县域为例

基于辽宁省2000年、2005年、2010年、2015年土地利用数据,综合运用当量因子法、主客观赋权法及探索性空间数据分析方法,分别测算辽宁省县域生态系统服务价值(ESV)及经济发展水平,衡量时空特征与空间集聚性,并通过耦合协调模型评估生态与经济效益的耦合协调状况,探究其空间差异。研究表明,辽宁省县域平均ESV呈波动性增长趋势,辽东ESV高,辽南、中部ESV低,辽西则由低转高;以沈阳和大连为代表的辽中、南部为经济发展高水平区,而辽西、东及北部经济发展处于较低水平;辽宁省县域生态与经济耦合协调平均状况表现为基本协调,空间分布上主要表现为东南部协调,而西部、中部及北部失调。

Based on the interpreted land use data of Liaoning in 2000,2005,2010 and 2015,the study used equivalent factor method and subjective and objective weighting method to measure ecological and economic benefits of each county in Liaoning Province from temporal and spatial characteristics views.Lately,this also used Exploratory Spatial Data Analysis method to estimate spatial aggregation respectively.In the end,this used coupling and coordination analysis to evaluate the coordination index of the county's ecology and economy,so that it could analyze spatial changes.The research showed that:The average ESV of Liaoning all counties presented a fluctuated increasing trend.From spatial view,it found out that the ESV was high in eastern Liaoning,but low in southern and central Liaoning.While western Liaoning’ESV changed from low to high.High economic development areas were concentrated in the central and southern Liaoning,forming two high-level points with Shenyang and Dalian as the center.However,the economy development of western,eastern and northern Liaoning was still at a low level.The average coupling coordination value in various counties were basic balance.From spatial view,it mainly showed that southeast Liaoning was coordination,while west,middle and north area in Liaoning were imbalance.
