摘要
根据2011年TM影响图提取渭河流域地区的居民点、DEM、水系、道路等空间信息数据,利用核密度估计分析法研究了渭河流域居民点及镇驻地的空间分布格局及其影响因素。结果表明:第一,渭河流域研究区内镇驻地大多分布于居民点集中的区域,居民点整体分布较为分散,在北部、西南部和东南部地区较为集中,符合典型的高山峡谷地带大散居、小聚居的农村居民点分布特征;第二,渭河流域研究区内居民点的空间分布模式与我国农村居民点分布的普遍特征类似,主要有3种:在高程低、坡度缓的区域主要表现为片状分布,道路两侧及河谷地区主要表现为带状分布,海拔较高地区主要表现为分散分布;第三,地形制约、城镇带动、交通影响、水系吸引、政策引导等因素对其居民点的空间分布格局均有着重要的影响,居民点在高程低、坡度缓、城镇周边以及道路两侧居民点较为集中。研究结果可为居民点整合规划提供参考。
The spatial distribution pattern of towns and settlements in Wei River basin were studied,using different data such as DEM,settlements,rivers,and roads by GIS spatial analysis method.The results of this paper are as follows：First,settlements are scattered in Wei River basin,most of them are in the north,southwest and southeast area,where towns are mainly in ; Second,there are three spatial distribution patters in Wei River basin：lamellar distribution in low altitude slow slope area,strip distribution on both sides of roads and rivers,dispersion distribution in high altitude area; Third,terrain conditions,roads,rivers,urban development and policy have important impacts on spatial distribution pattern of towns and settlements in Wei River basin.The study can provide reference for residential general planning.
