五常市北部地区农村居民点用地适宜性评价与整治分区规划

农村居民点用地适宜性评价是实现农村土地合理布局、挖掘土地整理潜力的重要依据。以五常市北部地区为例,从自然、经济社会和生态三方面构建典型粮食产区农村居民点用地适宜性评价指标体系,结合地区内部特点量化指标因子;依据适宜性评价分级和区域模式差异,综合考虑人口城镇化影响实现居民点的整治分区规划。结果表明:北部12个乡镇中农村居民点用地适宜性区间为0~3.996 8,不存在最高适宜的居民点用地,域内以高适宜和中适宜用地为主,低适宜和不适宜的居民点用地相对比例之和5.02%,地区仍有部分居民点需重点整治;兴隆乡、营城子乡、民乐乡等部分地区应引导村内人口外迁,八家子乡、常堡乡、牛家镇等应积极迁村并点,兴隆乡部分地区、八家子乡和卫国乡实施内部改造,保留发展型均有分布。研究结果可为该地区居民点整理规划提供科学依据。

Suitability Evaluation and Consolidation Division of Rural Residential Areas in Northern Wuchang

Suitability evaluation of rural residential areas is to realize the reasonable distribution of rural land, mining an important basis for land consolidation potential. Taking northern area of Wuchang as study case, the suitability evaluation index system was setup for rural residential land in typical grain-planting areas based on three factors of nature, economy and society and ecology.The indexes were quantified by combining with regional internal characteristics. The zoning plan of consolidation of residual areas was realized by comprehensive consideration of population urbanization influences according to the difference of the suitability evaluation and the regional pattern. The results showed that the suitability of rural residential areas ranged from 0 to 3.996 8 for 12 villages in northern Wuchang City, dominated with high and middle suitable classes, the proportion of low suitable and unsuitable classes was 5.02%, no highest suitable class existed. There were some rural residential areas need key consolidation. Villager relocation should be guided in parts of Xinglong, Yingchengzi, Minle and other villages, while village relocation should be considered positively for Bajiazi, Changbao and Niujia villages or town, the internal reform could be conducted in parts of Xinglong, Bajiazi and Weiguo villages on the basis of residential reservation. The above results can provide scientific bases for the consolidation planning of the regional residential land.
