山地丘陵地区乡村聚落的空间分布特征

通过景观指数分析、空间自相关性分析、空间分析，以桃源县为例，对山地丘陵地区乡村聚落的空间分布特征进行研究。结果表明:桃源县乡村聚落密度及其用地规模的空间分异特征显著，聚落总体形状较为简单，其中沅水、白洋河、延溪流域的乡村聚落形状相对较为复杂，规则性不强。桃源县各乡村聚落之间距离的空间分布格局特征并不明显，聚落之间的联系紧密，且水域对聚落空间分布的影响程度较强，最邻近道路距离的空间分布格局特征并不明显。桃源县的乡村聚落规模、形态结构、聚落与水域邻近度的空间特征显著，其空间关系差异显著。

Distribution Characteristics of Mountainous and Hilly Areas of Rural Settlements Space

The purpose of this paper is to reveal the spatial distribution characteristics of rural settlements in mountainous and hilly area in China. The research methods include landscape index analysis, spatial autocorrelation analysis and spatial analysis. The results show that the rural settlement density in Taoyuan county and its land use scale spatial characteristics are significant; the settlement overall shape is simple; the Yuanshui, Baiyang River and Yan River Basin' settlement shape is relatively complex; the rule is not obvious. The spatial distribution feature of distance between Taoyuan County Rural settlements is not apparent, and there is a close relationship between each settlement. The settlements are closely linked, and the impact on the spatial distribution of water is strong, and the nearest road distance spatial distribution pattern is not obvious too. The Conclusions: The difference of spatial relations such as rural settlements scale in Taoyuan county, spatial structure, significant features of settlement and adjacent waters, is significant.
