针对平原县域农村居民点空间分布现状,以江苏徐州市铜山区为例,研究其居民点的分布模式、景观布局特征及分析居民
点的交通状况。应用GIS空间分析技术、计算几何学中的Voronoi空间数据模型、景观指数法相结合的方法,分析了平原地区
县域农村居民点空间分布特征。通过对铜山区土地利用数据分析得出:铜山区居民点呈集团式布局,居民点规模差异较大,其中
以小面积居民点为主,并间有一些零散的居民点,大部分居民点交通便利。因此,农村居民点的整治和规划,应该综合考虑农村居
民居住习惯的差异,制定出合理的优化方案。
Abstract
According to the countylevel distribution of the rural settlements the distribution mode, the
landscape characteristics and the traffic conditions of the settlements were examined using the Tongshan district
of Xuzhou city in Jiangsu province as our study case in this work. Based on the spatial analyses of GIS, the
Voronoi analysis of the computational geometry coupled with the indices of landscape ecology, the distribution
characteristics of the rural settlements over Tongshan district were assessed. Results showed that a clustering
distribution was observed in the rural settlements, and there was a distinct difference in the settlements size.
Smallscale settlements dominated in this county, accompanying some sparsely distributed settlements, and
traffic condition of most settlements was convenient. The living habits of the rural dwellers should be carefully
taken into consideration when planning and regulating the layout of the rural settlements.
