摘要： 基于2015年文县土地利用变更数据和相关统计数据，根据农村居民点的现状分布规律，运用GIS空间分析和景观生态学理论，空间韵律测度、局聚类检验、平均最近邻指数、空间热点探测分析等方法，定量分析了文县农村居民点空间分布格局特征。结果表明：（1）文县农村居民点主要沿着交通道路和河流错落分布，形成以道路和河流网分布为主的枫叶状；（2）文县农村居民点用地规模普遍偏小，空间上呈现出低值集聚，高值离散的特征，在天池镇、城关镇等地区形成了小规模村庄集群分布的“冷点区”，在范坝镇等地区形成了大规模的农村居聚落集中分布的“热点区”；（3）受资源条件、自然区位及人类活动等因素影响，文县农村居民点在空间上以集群式和随机型分布为主；（4）文县农村居民的分布呈具有明显地域差异的集聚模式，整体形成了以范坝镇、碧口镇为中心的高密度区，并依次向北、向西、向南以阶梯形式逐渐稀疏的低密度区；（5）全县农村居民点聚落形态整体相对规则、整齐、破碎化程度较低，呈现较为平稳的演化形态，局部地区居民点分布形态复杂程度较高，东西走向规模分异明显，复杂程度由东向西逐渐减弱。

Abstract: Based on the data of land use and related statistics of Wen County in 2015, this paper quantitatively analyses the spatial distribution pattern characteristics of Wen County rural residential by using the theory of GIS spatial analysis and landscape ecology as well as the method of Spatial Metrics, cluster clustering test, the average nearest neighbor index, spatial Hot spot detection and analysis of the model. Results indicate five phenomena: first, Wen County rural settlements scatter mainly along the traffic roads and rivers, forming maple-like shape based on road and river network distribution; second, as for the scale of rural residential land, Wen County is generally small in size, showing low-value gathers and high-value discrete features. In Tianchi Town, Chengguan Town and other area, the "cold spots" of small-scale village clusters are formed while in Dam town and other regions the "hot spots" of large-scale rural areas distribution are taken shape；third, the rural settlements of Wen County are dominated by cluster and random distribution in space under the influence of resource conditions, natural location and human activities；fourth, the distribution of rural residents in Wen County showed a clustering pattern with obvious regional differences, however, the high density area centered on Fanba Town and Bikou Town, in general, was formed, which were gradually sparsely low toward the north, the west and the south; fifth, the rural settlements in the whole county is relatively neat and its fragmentation is low, showing a relatively stable evolutionary form. The complexity of the distribution of settlements in the local area is high, and the scale of east and west is obvious, and the complexity is gradually weakened from east to west.
