全球人口在地球陆地上的分布并不均匀，人口空间分布是指地球表面人口在质量和数量上的变化。在传统研究中，人口的空间分布是在行政单位层面上表现出来的，人口数据是用统计方法每十年收集一次。随着现代技术的发展，越来越需要更高空间分辨率的人口数据分布来满足“数字地球”研究的要求。最近获得的高分辨率遥感数据和图像处理方法使实现这些目标成为可能。人口分布受土地利用类型、人口统计学、区域生态等因素的影响。遥感数据和地球物理数据的综合分析有助于量化人口与大陆地理和气候等基本地球物理参数之间的空间关系。利用中国1995年全国人口普查数据和Landsat TM影像获取的土地利用数据进行案例研究，发现人口密度与土地利用类型直接相关。以五种主要土地利用类型为主要因子，建立了中国农村土地利用再分配格局。本文介绍了这些研究中使用的方法和主要算法。讨论了本研究的特点和前景。
The global human population are not uniformly distributed on Earth's landmasses spatial distribution of population means the variations of human population in terms of quality and quantity on Earth surface. In traditional studies, Spatial distribution of population were represented on administration unit levels, and population data were collected about every ten years with statistical methods. With the development of modern techniques, distributing population data with higher spatial resolution are more and more needed to meet the requirement of "Digital Earth" study. The recent availability of high resolution remote sensing data and image processing methods now make it possible to achieve these goals. Distribution of population is influenced by many factors such as land use types, demology, regional ecology, and so on. Integrated analysis of remote sensing data and geophysical data give much help to quantify the spatial relationships between population and basic geophysical parameters related to continental physiography and climate. Supported by case study in China using state census data of 1995 together with landuse data derived by Landsat TM images, it was found the population density is directly related to land use types. Selected areas of five main landuse types as main factors, a redistributing pattern had been established for Chinese rural areas. Methods and main algorithms used in these studies were presented in the paper. Characters and prospect of this study were also discussed.
