摘要
湖北省丹江口水库区是南水北调中线工程的水源区。随着调水工程的实施，库区土地资源将受到深远的影响。以丹江口水库及其四周海拔低于２００ｍ的区域为研究范围，选用９０年代初获取的ＬａｎｄｓａｔＴＭ假彩色合成图像为主信息源，运用目视判读和地理信息系统（ＧＩＳ）方法，对该区的土地资源利用现状进行了比例尺为２５万分之一的遥感制图和计算机面积量算；在此基础上，对工程实施后本区土地资源的淹没损失、土地利用结构的变化进行了宏观分析，进而对区域土地资源的合理利用进行了初步探讨。
The middle route of “south to north water transfer project” will have great effects on the land resources in Danjiangkou Reservoir Area which will be the water supplying area in the project.The scope of the present study comprised the Reservoir and an area where the altitude is below 200 meters around the reservoir in Hubei Province.Based on the visual interpretation of Landsat TM images for land use at a scale of 1∶250 000 and on the using of GIS,the authors perform a land use inventory,make a primary estimation of the losses of the land resources which will be inundated with water due to the project,and provide a macro analysis of the changes of the land use structure.Further,some suggestions are given on the planning and utilization of the land resources in the area.
