乡村“三生”空间综合评价与空间优化研究

Research on Comprehensive Evaluation and Spatial Optimization of Rural Production,Living and Ecological Space

对乡村“三生”空间进行综合评价是了解乡村“三生”空间综合发展水平的有效途径,“三生”空间的协调度分析则能反映各类“三生”空间发展的均衡性。以江西省吉安县永和镇为例,构建乡村“三生”空间综合评价指标体系和协调度模型,测算乡村“三生”空间发展水平和协调度;根据各行政村“三生”空间发展水平及其协调性对乡村“三生”空间进行优化研究。结果表明:永和镇各行政村“三生”空间发展水平偏低,整体评价分值较低,且生活空间>生态空间>生产空间;各行政村“三生”空间的生产—生活、生产—生态、生活—生态协调度不一,存在“三生”空间发展不协调的问题。根据永和镇“三生”空间发展水平和协调度状况,采取农业规模化经营与发展特色种植业的方法来优化生产空间,划分城镇融入型、集中发展型、拆迁集约型类型优化生活空间,采取划定生态红线、建立生态走廊优化生态空间。

The comprehensive evaluation of rural production,living and ecological space is an effective approach to understand the comprehensive development level of rural production,living and ecological space.The analysis of the coordination degree of production,living and ecological space can reflect their coordination of development.Taking Yonghe Town,Ji an County,Jiangxi Province as an example,this paper calculates the development level and coordination degree of rural production,living and ecological space by constructing comprehensive evaluation index system and coordination degree model of the rural production-living-ecological space.The optimization study of rural production,living and ecological space is carried out according to the development level and coordination of production,living and ecological space in each administrative village.The results show that the development level of production,living and ecological space in the administrative villages of Yonghe Town is low,the overall evaluation score is low and the living space is larger than ecological space that is larger than production space;the coordination degree between production and living,production and ecological,living and ecological in each administrative village is different since uncoordinated special development of production,living and ecological space.In view of the development level and coordination degree of production,living and ecological space in Yonghe Town,scale operation of agriculture and development of characteristic planting industry will be adopted to optimize production space,urban integration,centralized development,demolition and intensive types will be divided to optimize living space,and delineation of ecological red lines,establishment of ecological corridors will be accepted to optimize ecological space.
