中文摘要	以沙漠化问题突出的彰武县作为研究区,基于Landsat影像采用决策树分类模型提取2008年、2013年和2018年的沙化土地信息。运用转移矩阵和景观格局指数对分类结果综合分析,同时采用马尔科夫模型预测2023年土地沙化趋势。结果表明:20082018年彰武县非沙化土地面积大幅度增加;轻度沙化土地面积先增大后减少;中度和重度沙化土地面积显著下降,沙化程度明显减轻;预测2023年非沙化土地面积增长到2 505.970 4km~2,占总面积的69.21%,重度沙化土地面积几乎为0。
英文摘要	To a more prominent problem of desertification in Zhangwu County for example,based on the Landsat remote sensing images,the desertification information of the study area in 2008,2013and 2018was extracted by using decision tree model.The classification results were synthetically analyzed by transfer matrix and landscape metrics,and the trend of land desertification was predicted by Markov model.The result showed that the area of non-desertification land increased greatly from 2008to 2018.The area of slight desertification land firstly increased and then decreased.The moderate and severe desertification area decreased significantly,and the degree of desertification was greatly reduced.It predicted that the nondesertification land area would increase to 2 505.970 4km~2 in 2023,accounting for 69.21% of the total area.The severe desertification area would be almost 0,and the degree of desertification would be further reduced on the original basis.
