| 摘 要： | 利用1979、1989、1999、2008、2012年Landsat TM/MSS遥感数据,在地理信息系统与遥感技术的支持下,结合地面调查、核查等相关信息的基础上,对阿拉善盟境内黄河西岸地区水域湿地现状及其动态变化进行分析。结果表明:黄河西岸地区1979年水域湿地面积为76.21 km2,2012年的为50.05km2,减少了26.16km2,水域湿地面积以0.79km2/a的速度减少,其中1979—1999年间减少的速度最快,为1.49km2/a,1999—2012年间处于没有明显变化状态。

| Abstract: | Using the Landsat TM/MSS remote sensing data in 1979, 1989, 1999, 1989, 2012, with the support of geographic information system and remote sensing technology, combining with the ground survey and verification,on the basis of relevant informations, the status and dynamic change of water area wetland which is in Alxa area in the west bank of the Yellow River are analyzed. The results show that the water area wetland area of the west bank of the Yellow River area is 76.21 km2in 1979, and it reduces 26.15km2compared with 50.05km2in 2012.The wetland area is decreasing at a rate of 0.79 km2/ a, and it reduces fastest between 1979 and 1999 at a speed of 1.49 km2/ a. While, there is no obvious change from 1999 to 2012. |
