【摘要】：整理分区划定和整理潜力测算是农村居民点整理的核心内容。本文综合地形位、缓冲区、可达性、景观指数和Voronoi图,引入空间分异特征指数,定量分析农村居民点用地特征,实现整理区合理划分;改进潜力测算模型,结合经济社会、土地利用、农户意愿因素,构建整理潜力综合评价指标体系,以秦巴山区竹溪县为例进行实证研究。结果表明:竹溪县农村居民点空间分异特征指数值位于0.0433—0.8038之间;全县农村居民点可分为优先整理区、重点整理区、优化调控区和城镇发展区,现实潜力904.63 hm2,仅为传统潜力的65.42%;根据各乡镇潜力系数,划分为3级潜力区。空间分异的潜力测算、整理区和潜力区划分,为确定因地制宜的整理模式和符合实际的整理时序提供依据。
[Abstract]:Zoning and consolidation consolidation potential calculation is the core content of rural residential land consolidation. The terrain, buffer, accessibility, landscape index and Voronoi map, introducing the spatial differentiation characteristics index, quantitative analysis of the characteristic of land use in rural residential area consolidation, to achieve a reasonable division; improvement potential calculation model, combined with economic society and land use, farmers' willingness factors, constructing consolidation potential evaluation index system in Qinba mountain area of Zhuxi County as an example of empirical research. The results showed that: Zhuxi County Rural residential spatial distribution index located in the 0.0433 - 0.8038; the county's rural residents can be divided into priority consolidation area, key consolidation zone. Optimization of district development area and urban regulation, the realistic potential of 904.63 Hm2, only 65.42% of the traditional potential; according to the township potential coefficient, divided into 3 potential areas. Estimates of potential spatial differentiation, Qu Heqian finishing The division of the force area provides the basis for determining the arrangement pattern of the local conditions and in accordance with the actual arrangement of the arrangement.
