北京山区农村居民点分布变化及其与环境的关系

Relationship between distribution changes of rural residential land and environment in mountainous areas of Beijing

当前农村居民点整理工作应加强对社会经济转型条件下农村居民点内在演化规律的研究。该文应用GIS空间分析以及景观指数的定量分析方法,以北京山区为研究区域,分析研究了山区不同地域层次上农村居民点分布及其变化与该区自然环境、生产环境和社会经济三方面环境要素间的相互关系。结果表明北京山区农村居民点分布格局受坡度、高程、农用地以及城镇和交通道路等自然环境、生产环境和社会经济环境的综合影响,但其分布变化则更多地与农用地距城镇的距离和交通条件紧密相关。该文还对农村居民点分布的变化趋势进行了分析,为科学指导农村居民点整理提供依据。

The research on the inner evolvement law of rural residential land should be strengthened especially in the era of rapid socio-economic transition, which is of great significance to the rural residential land consolidation nowadays. Taking the mountainous area of Beijing as study case, the interactional relationship between the distribution changes of rural residential land and three environmental aspects including natural environment, product environment and social-economic environment was analyzed, by using GIS and landscape ecology method. Results show that rural residential land spatial distribution is affected by slope, altitude and the their distance to farmland, town and road, while its spatial distribution change is correlated more closely by the distance from farmland to town and road. Also, this paper analyzed the change trend of the rural residential land briefly, which can offer an academic basis for the rural residential land consolidation in practice.
