基于生态位的农村居民点用地适宜性评价与分区调控

    Suitability evaluation and subarea control and regulation of rural residential land based on niche

    • 摘要: 在剖析农村居民点用地生态位特征的基础上,按照新农村建设的要求,从生态条件、生产条件和生活条件3个方面选取相关指标,利用生态位适宜度模型与GIS栅格技术进行评价指标的单因素量化分析和多因素综合评价,将北京市平谷区划分为农村居民点用地高度适宜、中度适宜、低度适宜和不适宜4个等级。在此基础上,使用聚类分析法将平谷区现状的275个行政村划分为重点发展区、适度挖潜区、限制扩建区和优先整治区,进而分析了各区域用地特征,并提出相应的用地调控模式。研究结果体现了土地利用的适宜性和现势性,符合当地实际,对农村居民点整理和乡村土地规划具有指导意义。

       

      Abstract: In this paper, with the analysis of ecological niche characteristics of rural residential land, relevant indicators were selected for considering the ecological conditions, production conditions and living conditions. Taking Pinggu district as study area, with the help of niche-fitness model and GIS, single-factor quantitative analysis and multi-factor comprehensive evaluation were used to divide the district into highly suitable, medium suitable, low levels of appropriate and inappropriate for rural residential land use, as well as key development areas, moderate potential areas, restricted expansion areas and priority remediation areas were formed for 275 administrative villages based on the results of suitable evaluation and cluster analysis method. Furthermore the characteristics of the regional land use were concluded and corresponding regulation and control modes were suggested. The results reflect the land use suitability and current trend, accord with local conditions and share a strong guiding significance for the consolidation of rural residential area and rural land-use planning.
