- 摘要:
- 为探究太行山深山区农村居民点的地形分异特征，以河北省阜平县为例，选取了高程、坡度、坡向、地形起伏度、平面变率、剖面变率6个地形因子，通过区位熵指数反映农村居民点空间分布的优势地形位，运用洛伦兹曲线和基尼系数反映各地形因素不同分级梯度上居民点空间分布的集中程度，采用信息熵进一步分析农村居民点在各地形因素上的有序程度。结果表明：海拔高度在100～300 m以及300～500 m，坡度为0°~2°、2°~6°和6°~15°，坡向在平面、东北、东、东南和南向，地形起伏度在0～30 m，平面变率在20°以上，剖面变率在0°~5°内的区域为农村居民点在各地形因子上的优势地形位；平面变率各分级梯度上农村居民点的空间布局属于绝对均匀型，坡向、地形起伏度和剖面变率属于比较均匀型，而在坡度和高程上则属于分布悬殊型；农村居民点在地形起伏度、高程和坡度上的分布较为有序；优劣势地形位越明显的地形因素上，农村居民点的空间分布越集中，有序度也越高。从区位特征及内在结构进行定性和定量分析，可为山区农村居民点的布局优化提供科学决策。
- Abstract:
- In order to explore the terrain differential characteristics of the rural residents in in Fuping County of Taihang Mountain, Hebei Province, the elevation, slope, aspect, relief, plane strain rate, profile variable rate are selected, the location quotient index is used to reflect distribution of rural residential area in the advantage of the terrain, Lorenz curve and Gini coefficient are used to reflect the topographical gradients with spatial distribution of equilibrium degree, information entropy is used to analyze the order degree of the rural residents in different terrain factors. The results showed that altitudes with 100~300 m and 300~500 m, slope in 0 to 2 degrees, 2~6 degrees and 6 to 15 degrees, aspect in plane, northeast, east, southeast and south, relief degree in 0~30 m, plane strain rate in more than 20 degree, profile variable rate in 0~5 degrees are the dominant positions of the rural residential land in various topographic factors. Plane strain rate on rural residential areas of spatial layout belongs to the absolute uniform type, aspect, relief and profile variable rate belong to a relatively uniform type, the elevation belongs to the type of distribution disparity. The distributions of the rural residential land in the relief, elevation and slope are more orderly. The terrain factors of the superior and inferior position are more obvious, the spatial distribution of rural settlements is more concentrated, and the degree of order is higher. This paper does qualitative and quantitative analysis of the location characteristics and the internal structure and can provide scientific decision making for the layout optimization of rural residential area in mountainous areas.
