淮河上游沿河平原乡域农村居民点空间分布特征研究——以潢川县魏岗乡为例

以魏岗乡为例,研究淮河上游沿河平原农村居民点的空间分布模式以及农村居民点空间分布的相关因素.结果表明,该区农村居民点总体呈现一种随机分布的模式,局部呈现聚集、团状、带状分布格局;居民点在各个坡向均有分布,以东南方向最多,正东方向、西北方向、东北方向稍多.农村居民点受道路、海拔、坡度影响比较明显,受坡向影响相对较小.在局部区域内受道路交通、地形制约比较明显;随着海拔及距离的增加,居民点面积呈现先增加后减少的趋势,不同区域范围内居民点面积差别很大;随着坡度的增加,居民点面积呈现出不断减少的趋势.

Spatial Distribution Characteristics of Rural Settlement for Country Domain in the Flatlands along the Huaihe River Upper Watershed---Taking Weigang County As an Example

The rural settlement spatial distribution for country domain in the flatlands along the huaihe river upper watershed was studied. The results showed that the overall rural settlement were in a random distribution model and some local areas were disequilibrium with ribbon pattern and round shapes. The rural settlement was distributing in all aspects,and the largest part was in the southeast,and larger in south、northwest and northwest.It was concluded that the spatial distribution characteristics of rural settlement was obviously affected by road、elevation、slope,and slightly affected by aspect. With the rising of elevation and the distance increasing to roads,the surface of rural settlement increased first and then decreased; with the increasing of slope,the surface of rural settlement decreased.
