克拉玛依市土地荒漠化现状及其动态分析

Status and Dynamic Analysis on Desertification in Karamay City

以克拉玛依市为研究对象,采用遥感与地理信息相结合的方法获取研究区土地利用类型、荒漠化现状及2004年荒漠化状况。调查结果表明,研究区荒漠化土地在减少,在荒漠化类型及程度中,确定了研究区域以风蚀和盐渍化并存的荒漠化类型,10年间,风蚀和盐渍化荒漠化程度在减轻。

Taking Karamay City as research objects ,land‐use types in the research area ,desertification status and de‐sertification status in the year of 2004 were obtained by using method of combining remote sensing and GIS .Result shows that desertification land are decreasing in the research area;desertification type of coexistence of wind erosion& salinization in the research area is determined in desertification type and extent ;wind‐erosion desertification and salinization desertification are decreasing in the recent 10 years .
