新农村建设如火如茶,新的城乡一体规划正在逐步开展,乡镇居民点优化布局与整理受到人们空前的关注,探讨乡镇居民点的空间分布特征的方法技术需求迫切。将GIS与Voronoi图相结合,研究乡镇居民点空间分布特征及其影响因子,以信阳市为例,分析了地形、公路及河流等自然、社会生产环境因素对乡镇居民点空间分布特征的影响。
The new countryside construction is like a fire, the new integrated planning of urban and rural areas is being carried out progressively. The optimization of layout and arrangement of township settlements has received unprecedented attention. The methodological technical requirements of exploring the spatial distribution characteristics of township settlements are urgent. The GIS and Voronoi diagram are combined to study the spatial distribution and impact factors of township settlements. Taking Xinyang as an example, the influences of natural and social factors such as topography, roads and rivers on the spatial distribution of township settlements are analyzed.
