摘要
以宁夏盐池县为研究区域,采用盐池县1986、1989、1995、1999、2003及2006年的6景TM影像数据,结合野外GPS空间定位技术,在GIS软件的支持下,进行了盐池县土地荒漠化演化规律分析。结果表明,该区荒漠化土地的演化过程表现出两个明显的阶段,1986—1995年为荒漠化明显发展阶段,1995—2006年为荒漠化明显逆转阶段。
Taking Yanchi county as the studied area,the paper analyzes the law of desertification evolution,using TM image data of 1986,1989,1995,1999,2003 and 2006,combining with the field GPS spatial positioning technique and with the support of GIS software.The outcomes show that there are two obvious phases in the desertification evolution,i.e.1986-1995 is the rapid development phase of desertification and 1995-2006 is the notable inversion phase of desertification.
