摘　　要：文章运用GIS空间分析技术,以四川省汶川县为研究区域,对居民地的空间分布特征及其影响因素进行分析。研究结果表明:汶川县居民地大体呈条带状分布,具有强烈的低海拔取向,其分布的优势地形区段为海拔2000m以下,居民地分布具有明显的沿河分布特征;在乡镇层面上汶川县居民地呈现一定的集聚分布特征,主要分布在海拔较低的水磨镇、漩口镇及县城所在地威州镇。研究成果可为汶川县居民地的整治规划提供参考。Taking Wenchuan County in bichuan province as an example, tins paper anaiyzeo me spanai olstn- bution characteristics of the settlements and the in{lueneing factors using GIS spatial analysis technology. Results showed that the settlements of Wenchuan County appeared to be banded distribution, had strong low altitude ori- entation, and the dominant elevation section of settlements distribution was less than 2000m. The settlements had obvious characteristic of distributing along the river. Moreover, the settlements presented a certain aggregated dis- tribution characteristics in the township level and they mainly distributed in Shuimo town, Xuankou town whose elevations are lower and the county seat--Weizhou town. The research results could provide a reference to the ren- ovation and planning o{ settlements in Wenehuan.
