摘　　要：运用RS/GIS技术,根据有关统计资料及遥感资料对江汉平原湖区的范围和土地资源进行了分析.考虑湖区发育背景、资源环境结构和社会经济功能等方面的因素,将江汉平原湖区界定为湖北省境内以江汉平原为依托的、海拔50m等高线以内的所有地区.其范围在111°36′38.76″～116°7′52.14″E、29°25′59.25″～31°27′14.45″N之间,按自然界线计算面积为4.664万km2,按行政区统计面积为6.475万km2.通过遥感图像的判读分析、实地抽样并结合相关资料,得出了1995年及2000年江汉湖区土地资源及其利用的调查分析结果,揭示了土地资源及其利用的变化规律.<Abstrcat> With the help of the technique of RS and GIS, it analyzes the land resource in Jianghan Lake Zone under the basis of statistical data and remote sensing images. Considering the growth background, structure of resources and environment, and social (economic) function in this area, it defines Jianghan Lake Zone as the area under the altitude of 50 m in Jianghan Land in Hubei province, which covers the area from (111°36′38.76″E) to 116°7′52.14″E in longitude and from 29°25′59.25″N to 31°27′14.45″N in latitude. The acreage is 46.64×10~3 km^2 in geographic calibration amd 64.75×10~3 km^2 in regionalism. This paper gets the investigation and analysis results of the land source, as well its use of Jianhan Lake Zone in 1995 and 2000, after determining analysis and field sampling of the remote sensing images in 1995 and 2000. According to the comparative analysis, the paper discloses the variation principle of land resource and its usage in Jianghan Lake Zone from 1995 to 2000.
