摘  要：
本文利用遥感和地理信息系统等技术,对农业土地资源结构及空间分布特征进行了分析。研究发现西藏边境县农业土地资源结构差异较大,农业土地利用资源总面积约为348 057 km~2,其中可以用于农业发展的耕地、林地和草地的面积各为4603、76 250、143 511 km~2,占总面积的1. 32%、21. 91%、41. 23%。草地资源所占比例最大,耕地面积最小。各边境县农业土地资源分异明显,耕地和林地主要分布在西藏的东南部地区,草地多分布在西北和西南地区。

摘  要：
In this paper,the structure and spatial distribution characteristics of agricultural land resources were analyzed by using remote sensing and geographic information system. It is found that the structure of agricultural land resources in the border county of Tibet was great significantly different. The total area of agricultural land use resources was about 348 057 km~2,among which the area of arable land,forest land and grassland that could be used for agricultural development was 4603,76 250 and 143 511 km~2 respectively,accounting for 1. 32 %,21. 91 % and 41. 23 % of the total area. The proportion of grassland resources was the largest and the area of cultivated land was the smallest. The agricultural land resources of each border county were obviously different. The cultivated land and forest land were mainly distributed in the southeast of Tibet,and the grassland was mostly distributed in the northwest and southwest.
