| 摘 要： | 通过对1987年和2001年TM影像数据的解译和分析,研究了疏勒河流域荒漠化土地发展动态和趋势。结果表明:14a来疏勒河流域荒漠化土地面积总体呈减少趋势,荒漠化土地总面积减少了56985.5hm2;其中风蚀荒漠化和盐渍荒漠化土地面积均呈减少趋势,到2001年分别为14897.5hm2和4272.2hm2;水蚀荒漠化土地面积有所增加,2001年与1987年相比增加了52.3hm2;尽管酒泉市的荒漠化土地面积普遍表现为绝对数值在减少,但就各年份荒漠化发生的程度来说,荒漠化现象在2001年要比1987年程度要严重。结合流域实际情况,为荒漠化土地逆转提出具体的防治措施。

| Abstract: | Through interpretation and analysis of TM image data in 1987 ＆ 2001 ,development dynamic ＆ tendency of the Shule River Basin desertification land were studied. Result shows that： in the recent 14 years,desertifieation land area of Shule River Basin,which decreased by 56 985.5 hm2, has a tendency to reduce;wind erosion ＆ saline land desertifieation all show tendency to go down, being 14 897.5 hm2 ＆ 4 272.2 hm2 respectively in 2001 ; area of water-erosion land-desertification,which increase by 52.3 hm2 in 2001 compared with 1987 ,increases slightly;Although desertification land area of Jiuquan city generally shows reduction of the absolute value,to the degree of desertifieation in each year, the phenomenon of desertifieation in 2001 is more serious than that in 1987. Concrete measures for desertifieation reverse were put forward, combined with actual situation of river basin. |
