| 摘 要： | 利用1987年和2000年美国陆地卫星TM数据资料,对青海省龙羊峡库区13 a来土地沙漠化面积、分布、发展等动态进行了监测,发现龙羊峡库区沙漠化总面积的净扩大量并不很大,只有15 220.6 hm2,沙漠化面积以平均每年1 170.8 hm2的速度递增,年递增率为0.55%,但沙漠化程度加大、等级增高的趋势明显。

| Abstract: | Investigation of desertification in Longyangxia reservoir region in Qinghai Province by using Landsat TM data of 1987 and 2000 indicated that the net enlarged desertification area of the region is only 15 220.6 km2,and the increasing area per year is 1 170.8 km2,the annual increasing rate is 0.55 percent;but the tendency of desertification degree and grade is obviously upgoing. |
