欠发达山区农村居民点整理潜力评价与空间分异研究——以福建省松溪县为例

Evaluation and Spatial Differentiation of Rural Residential Land Consolidation Potential in Underdeveloped Mountainous Areas:A Case from Songxi County,Fujian Province

欠发达山区的农村居民点整理潜力的测算受到多方面因素的影响，当前普遍使用的人均建设用地标准法存在计算简单、测算结果偏离实际等问题。本研究以福建省松溪县为例，综合考虑自然、社会、经济、生态以及土地资源现状5个方面的因素，构建农村居民点整理潜力综合修正指标体系，采用层次分析法、聚类分析法、AreGIS空间分析，探讨松溪县农村居民点整理现实潜力及其空间分异情况。结果表明各个评价单元综合修正系数介于0．1566～0．7141之间，2020年松溪县农村居民点整理现实潜力为315．43hm^2，总理论潜力转化率为38．20％；以整理现实潜力为主要依据，将全县划分为4个潜力分区，并为各分区整理模式和时序提出建议。

The calculation of rural residential land consolidation potential has been influenced by many factors in underdeveloped area. So far, the per capita construction land standard method has been widely usedto calculate the potential. However, this method faces problems, such as too simplified calculation process and too much deviation from actual situation. Taking Songxi County in Fujian province for example, andfully considering its natural, social, economic, ecologic and land resource conditions, a comprehensive index system to evaluate the rural residential land consolidation potential in the county is established. Resultsindicates that, for each evaluation units, the comprehensive correction coefficients should be between 0. 156 6 -0. 714 1. It is found that in 2020, the total rural residential land consolidation area of the countycan be as large as 315.43 hm^2, reaching a 38. 20% conversion ratio. The county is further divided into 4 partitions aceording to their different eonsolidation potential, and appropriate patterns and sequential arrangements for each parts are put forward.
