长沙市三生空间耦合协调发展评价研究

Evaluation of Coupling Coordinated Development of Sansheng Space in Changsha City

摘要: 我国城市建设经过数十年的高速增长，现今已迎来了减速时刻，城市的国土空间发展也面临着新的挑战。本文以长沙市为研究对象，首先采用长沙市2012、2017、2020三年的POI数据，为划定三生功能区域提供基础数据集；再通过构建指标评价体系开展长沙市三生功能评价和三生功能耦合性研究，分析长沙市三生空间功能变化与分布情况。研究结论如下：整体上长沙市生产和生态功能范围呈现相互交融，同势增长的态势，且生态功能数值也正逐年增长；从三生功能分布来看，长沙市东西部地区人口和相关建设相对较少，以第一产业为主，所以难以发展比较密集的生活与生产空间，生产与生活功能的耦合协调度较低，无法匹配较高的生态性；相反，长沙市中心六区以规模产业为主导，生产功能强，生活空间较为密集，其相应的生产、生活功能较高，所以与生态功能匹配度较高，所以中心区整体耦合协调等级较高。

Abstract: After decades of rapid growth, China’s urban construction has now ushered in a time of deceleration, and the development of urban land space is also facing new challenges. This paper takes Changsha as the research object. First, it uses the POI data of Changsha in 2012, 2017 and 2020 to provide a basic data set for delineating the Sansheng functional area; And then through the construction of the index evaluation system to carry out the evaluation of the Sansheng function in Changsha and the research on the coupling of Sansheng function, analyze the spatial function change and distribution of Sansheng in Changsha. The research conclusions are as follows: On the whole, the production and ecological function areas in Changsha are blending with each other and growing in the same trend, and the value of ecological function is also increasing year by year; from the perspective of the distribution of the three life functions, the population and related construction in the eastern and western areas of Changsha City are relatively small, mainly focusing on the primary industry, so it is difficult to develop a more intensive living and production space, the coupling and coordination of production and living functions is low, and it cannot match the high ecological characteristics; on the contrary, the six central districts of Changsha are dominated by large-scale industries, with strong production functions and dense living spaces. Their corresponding production and living functions are high, so they are highly matched with ecological functions, so the overall coupling and coordination level of the central district is high.
