摘要
以2005-2015年长江经济带11省市为研究对象,运用综合评价法对生态建设水平的时空变化进行分析,通过探索性空间数据分析和冷热点分析工具探索生态建设水平的时空集聚特征和时空演变情况.结果表明:2005-2015年长江经济带水生态指数、土壤生态指数、大气生态指数与生物生态指数持续上升,生态建设指数呈现出明显的空间自相关特性,靠近上游地区的中游省市向低高集聚区转变,邻近下游地区的中游省市向高低集聚区转变.2005-2015年长江经济带生态建设指数热点区域集中在中上游地区,逐渐由上游地区向中游地区扩大;冷点区域集中于中下游地区,逐渐由中游地区向下游地区缩小.
Taking the 11 provinces and cities of Yangtze River Economic Zone in 2005-2015 as the study object,the spatial and temporal changes of ecological construction level are analyzed using comprehensive evaluation method,through the exploration of spatial data analysis and hot-cold point analysis tools to explore the spatial-temporal clustering characteristics and spatial-temporal evolution of ecological construction level.The results show that:water ecological index,soil ecological index,atmospheric ecological index and bio-ecological index of the Yangtze River Economic Zone continues to rise during 2005-2015,the ecological construction index shows obvious spatial auto-correlation characteristics, the provinces and cities of midstream areas close to the upstream areas have turned to low-high concentration areas,while the provinces and cities of midstream areas close to the downstream areas have turned to high-low concentration areas.From 2005 to 2015,the hot-spot areas of ecological construction index in the Yangtze River Economic Zone are concentrated in the midstream and upstream areas,and gradually expandes from the upstream area to the midstream area,while the cold-spot areas are concentrated in the midstream and downstream areas,and gradually narrows from the midstream area to the downstream area.
