摘　　要：为探究新型城镇化对区域生态环境质量的空间影响,促进区域绿色和可持续发展,通过STRIPAT模型构建新型城镇化与生态环境的关系,运用全局Moran指数和局部Getis-Ord Gi*指数对淮河生态经济带新型城镇化水平与生态环境质量进行空间自相关分析,建立空间杜宾模型探究影响因子对生态环境质量的空间效应。结果表明:1)淮河生态经济带新型城镇化水平与生态环境质量存在正空间相关性,但其空间分布不均衡,2008—2017年新型城镇化水平空间分布格局基本一致,生态环境质量空间分布差距较大;2)空间溢出效应的估计结果显示,新型城镇化水平对生态环境质量具有正向溢出效应,提升新型城镇化水平有利于改善城市内部及周边地区生态环境质量;3)各控制变量对生态环境的空间效应不尽相同,其中产业结构对城市内部和邻近城市生态环境质量均存在正向作用,富裕程度和对外开放度仅对区域间生态环境质量产生负向空间交互作用,环保投入只影响区域内部生态环境质量。Cherishing the prosperous and sustainable eco-economic development of the Huaihe River economic belt,the present paper tries to make an exploration of the spatial influence of new urbanization on the regional ecological environment quality.For the said purpose,the paper has first of all built up a relationship between the new urbanization trend and the eco-environment status-in-situ via the so-called STRIPAT model. And,next,the newly formulated urbanization level and the ecological environment quality of the belt has been tested and measured with the comprehensive index method. And,what is more,the Global Moran index and the local Getis-Ord G*iindex have been taken to analyze the spatial autocorrelation between the novelty urbanization level and the eco-environment quality. Thus,we have eventually created the Spatial Dubin Model to explore the spatial effect of the influential factors on the eco-environment quality more profoundly. The results of the above situation indicate that:( 1) The spatial distribution of the new urbanization level and the ecological environment quality turn out to be disproportionally unbalanced in the Huaihe River economic belt,though there indeed exist somewhat positive spatial correlation situation between the 2 sides. For instance,for the ten years’ period from 2008 to 2017,the spatial distribution pattern of the new urbanization level has been remaining unchanged. Such a situation simply indicate that the spatial distribution pattern remains to be"high-value agglomeration in the northeast of the city and low-level agglomeration in the southwest". The spatial distribution of the eco-environment quality remains in a great gap. For example,in the ten years,the movement trajectory of the hot spots remains in the northeast to the southeast and then to the east,whereas the cold spots remain closed up in the west.( 2)The assessment results of the spatial spillover effect demonstrate that the newly urbanized areas indeed have positive spillover effect on the eco-environment quality.
