| 摘 要： | 玛曲县地处黄河上游,属江河源区,其生态作用对黄河的安危有直接影响。作者运用遥感与地面调查相结合的方法,对玛曲县的土地沙漠化及其发展趋势进行了研究。结果表明:全县沙漠化土地总面积6080.0hm2,基本沿黄河分布于冲洪积滩地,以每年6.8%的速率扩展。土地沙漠化是自然与人为因素共同作用的结果,以过牧为主导因素。沙漠化治理是黄河综合整治、高原湿地保护和牧区可持续发展的需要。

| Abstract: | Maqu county is in upstream of Huanghe river, the source of the river. This paper gives a research on desertification and its development trend in Maqu county, using the method of romote sensing and on|spot serveying. The results show that the total area of desertification land in the county reaches {6 080.0} hm 2 , desertification land distributes along Huanghe river, and it is expanding at the rate of 6 8% per year. And land desertication develops as a result of the comprehensive effects of environment and human activity. The controlling of desertification is needed for overall control of Huanghe River, conservation of plateau wet|field and sustainable development of pastoral area. |
