基于V图的农村居民点空间分布特征及其影响因子研究——以北京市昌平区为例

When the new rural reconstruction is like a raging fire and the new city and countryside body plan is developing gradually, the rural settlement optimization layout and the reorganization receive the people unprecedented attention. Discussing the method technology of the spatial distribution characteristic of the rural settlement demands to be urgent. Taking Changping area in Beijing as the example, this article unifying GIS and the Voronoi diagram, studies on spatial distribution characteristics and influencing factors of rural settlement and has analyzed terrain of natural, roads and rivers of the social product environmental factors and so on. The result shows the terrain is the influencing leading factor. The land proportion, the scale and the density are big on plain and relatively small in the mountainous area. The road is an important factor, and the distances of 91.19% rural settlements to be away from primary roads are smaller than 1500m. The rivers also have certain influence to the rural settlement spatial distribution. When the rural settlements are away from the rivers to be getting more and more far, the density of rural settlements in Changping takes on the obvious decreasing progressively tendency.
