- 摘要:
- 农村居民点空间布局优化是解决当前我国农村居民点空间布局分散与低效利用的一个重要途径。以湖南省麻阳县为研究区，应用GIS空间分析及景观指数分析相结合的方法，利用2005年麻阳县土地利用现状库为数据源，对其空间布局进行研究。结果表明：（1）麻阳县各乡镇农村居民点用地规模与密度差异明显，斑块形状不规则但地域差异小。（2）农村居民点空间布局存在着对耕地及道路依存度高的特征。（3）麻阳县农村居民点优化布局方案为控制性乡镇2个，发展性乡镇9个，拆并性乡镇12个，形成“两核四轴”的放射布局体系。
- Abstract:
- Optimum Spatial Distribution of Rural Settlements is an important way to solve the current distribution of scattered and inefficient use of rural settlements. In this paper, Mayang county is taken as an example, by means of GIS spatial analysis and landscape index analysis methods, using Land Use Data of Mayang county in 2005, the distribution of rural settlement was studied. The results showed that (1) The size and density differences of rural settlements in Ma yang county’s townships are significant, irregularly shaped patches but small regional differences; (2) Spatial distribution of rural settlements has characteristics of high dependence on the agricultural land and road; (3) Optimized spatial distribution of rural settlements in Mayang county is 2 controlled towns, 9 developing towns, 12 dissoluted towns, forming the radiation distribution system of ’two cores and four axis’.
