空间相关视阈下浙江省县域生态文明建设空间格局分析

生态文明是社会文明的重要表征,是经济、政治、文化、社会的重要组成部分。利用"2017年浙江省生态文明建设年度评价结果公报"的指标数据,对绿色发展指数及6个分维度指数的空间格局进行研究,探讨空间相关视域下浙江省县域生态文明建设的空间格局。结果表明：（1）浙江省各市域绿色发展指数及分维度指数的差异明显,杭州市的绿色发展指数最高,而嘉兴市的绿色发展指数处于最低水平。（2）浙江省绿色发展指数存在空间自相关特征,但Global Moran''s I并不高。在分维度指数中,除资源利用外,环境治理、环境质量、生态保护、增长质量和绿色生活都存在明显的空间自相关性。（3）发达县域间存在资本、人才和技术的流动,有足够的经济实力和技术投入到环境污染治理和防止、生态环境保护和修复中,形成绿色发展的扩散互溢区。而欠发达县域以资源环境为代价的不持续发展方式对提高绿色发展指数具有明显的制约作用,呈现极化效应和低速增长态势。（4）研究认为可利用空间相关性发挥县域间生态文明建设的带动作用,实现生态文明建设整体水平的提高。一方面要构建跨区域绿色发展的协作机制,落实跨区域的生态补偿机制;另一方面要积极发挥试点和示范的带动作用,产生正外部性溢出效应。

Spatial pattern of ecological civilization construction in Zhejiang Province from the perspective of spatial correlation

Ecological civilization is an important symbol of social civilization and an important part of economy, politics, culture and society. This paper uses the index data of the "Bulletin of 2017 Annual Evaluation Result of Ecological Civilization Construction in Zhejiang Province" to study the spatial pattern of green development indicators and six sub-dimensional indicators, and to explore the impact of spatial correlation on ecological civilization construction in Zhejiang Province. The results show that:(1) The differences between the green development indexes and sub-dimension indexes of different cities in Zhejiang are obvious. Hangzhou has the highest green development index, while Jiaxing''s green development index is at the lowest level. (2) There is spatial autocorrelation in the green development index, but the Global Moran''s I is not high. However, in the sub-dimension index, there are obvious spatial autocorrelations in environmental governance, environmental quality, ecological protection, growth quality and green life except resource utilization. (3) There is a flow of capital, talents, and technology among the developed counties, and there is sufficient economic strength and technology to invest in environmental pollution control and prevention, and ecological environment restoration and protection, forming a green development diffusion and spillover area. However, the unsustainable development mode of the undeveloped counties at the cost of resources and environment has obvious constraints on improving green development indicators, showing a polarization effect and a low-speed growth trend. (4) It is considered that the spatial correlation can play a leading role in the construction of ecological civilization among counties, and to improve the overall level of ecological civilization construction. On the one hand, we need to build a cross-regional green development cooperation mechanism and implement a cross-regional ecological compensation mechanism; on the other hand, we should give full play to the leading role of pilot and demonstration to produce positive externality spillover effect.
