| 摘 要： | 人口调查统计以行政区划为基本单元,数据精度不能满足较高分辨率的空间结构分析,也难以在地理综合研究中与自然地理要素数据相匹配.因此,人口密度空间化成为地理学的重要研究方向之一.本文基于贵州省猫跳河流域的乡镇人口数据,采用GIS空间分析技术与统计学方法,分析了人口密度与空间因子的关系;并采用多元回归的方法建立了人口密度数据...

| Abstract: | Population census is based on administrative unit,therefore,the data accuracy can not meet the high-er resolution analysis of the spatial structure and is difficult to match the data of physical elements in a compre-hensive analysis of geographic features.Thus,spatialization of population density becomes an important re-search direction in geography.Based on the statistical population data of villages in the Maotiaohe basin,this re-search first analyzed the relationship between population density and spatia... |
