Production-living-ecological Functional Evaluation of Central Henan Urban Agglomeration Based on Two-dimensional Graph Theory Clustering
摘要
Abstract
Based on the present situation of production-living-ecological function and rationally dividing it,its versatility is of great significance for promoting the high-quality development of urban agglomeration land space.Taking the Central Henan urban agglomeration for example,we discussed the evolution process of urban agglomeration production-living-ecological function by establishing the production-living-ecological function evaluation system and optimizing the territorial space based on two-dimensional graph theory clustering.The results show that ①the high value of production and living functions is located in the contiguous areas of Zhengzhou-Luoyang,Zhengzhou-Xuchang and other cities and continues to expand,while the high value of ecological function is mainly concentrated in the mountains of western Henan.②The production-liv-ing-ecological function has obvious gathering characteristics.From 1980 to 2020,the production function in the mid-east area continued to de-cline and showed a trend of fragmentation,and the living function continued to gather around the urban built-up areas and continued to stress the ecological function areas.③According to the two-dimensional graph theory clustering method,it is divided into five functional zones.According to the characteristics of different zones,Corresponding management and control strategies are proposed.关键词
