| 摘 要： | 青海湖是我国最大的内陆咸水湖,是世界著名的湿地,但随着周围地区荒沙漠化环境的恶化,其土地荒漠化也不断加剧。本文对青海湖地区土地荒漠化的自然特征和社会经济特征进行了分析,明确了荒漠化的环境背景。在此基础上,结合青海湖地区荒漠化土地普查与监察工作的范围和内容,采用ASTER卫星影像图对湖区周围地区进行解译,并利用解译数据对荒漠化土地进行等级划分,分析土地荒漠化的空间分布格局,对荒漠化作出综合评价。

| Abstract: | Qinghai Lake is the biggest salt lake in China, which is also a well-known wetland in the world. However, with the deterioration of the land desertification in the surroundings, desertification of the lake area also becomes aggravated. In this paper, the author firstly analyzed the basic natural, social and economic features of the study area to assess land desertification. Then the environmental background of land sandy desertification was specified. On this basis, the author, combining the content and scope of desertified land inventory with that of land desertification monitoring in Qinghai Lake, made an integrative assessment on land desertification in the lake area by adopting ASTER satellite image interpretation of the area; and classified the degree of land desertification and analyzed spatial distribution of land desertification by using the interpretation data. |
