太行山区河谷内居民点的特征及其分布格局的研究--以河北省阜平县为例

以河北省阜平县的5条河流主流河谷为案例，全面分析了河谷内居民点的斑块特征和分布格局，表明，河谷内的居民点位置基本是在的向阳一侧靠近坡脚的地方，一般以狭长形状为主；居民点面积在河谷面积中所占的比例在各个河段的变化很大，但不同河流居民点面积占河谷面积的比例十分接近，在10%-17%的范围内变支。在研究区内，河段内居民点的面积与河谷面积、河谷内农田面积是呈正相关的，表明本地区河谷内的居民对河谷土地具有很强的依赖性；河谷内的居民点增加使河谷林木急剧减少，但居民点内部和周围的河谷林木为其安全性、舒适性提供了保障。

Analysis on Characteristics and Distribution Pattern of Settlement in River Valley--A Case Study in Fuping County of Hebei Province

Based on landscape theories, taking five rivers in Fuping county of Hebei Province as an example, the patch characteristics and distribution pattern are analyzed. The results indicate that the position of settlement are mostly near the piedmont and its shapes are mainly narrow and long; the area proportions of settlement to valley vary remarkably, but the proportion between different rivers is quite similar, and vary between 10%-17%; the positive correlations of settlement area to valley and farmland area in valley are found, these show that the inhabitants have strong reliance to valley land; the increase of settlements lead the rapidly reduce of valley forest, but there are many trees distributed in and surround the settlements and those trees provide security and comfort for settlement.
