为探讨陕西省榆林市榆神府矿区土地荒漠化发展变化动态，采用1989、2002、2011年3期 TM遥感数据，对本区荒漠化进行分类，以此为基础分析荒漠化景观格局的变化。结果表明：①通过构建矿区归一化植被指数（NDVI）和地表反射率（Albedo）空间特征下的荒漠化遥感监测模型，可以将矿区荒漠化程度分为5种类型；②矿区土地荒漠化面积不断减少，1989-2002年间减少了39.7％，2002-2011年间减少了27.7％，荒漠化程度呈逆转趋势；③矿区荒漠化景观斑块在研究期趋于规则化，非荒漠化土地始终是主导景观类型，其优势度不断提升，非荒漠化斑块与其它级别荒漠化斑块类型的连接性不断降低。

The distribution and changes of desertification landscape pattern at Yushenfu mining area are inves-tigated by using the data sources from five periods TMremote sensing image,i.e.1 989,2002 and 201 1 .The re-sults show that:①A remote sensing monitoring model based on NDVI and Albedo is founded to demonstrate the in-formation about current status as well as dynamic changes of land desertification,on this way,it can be divided into 5 levels of desertification in the study area.②Land desertification area decreased 36.7% and 27.7% during 1 989-2002 and 2002-201 1 ,respectively,making desertification degree showed a reversal trend.③Desertification landscape patches had became more rules,and the non-desertification land had been dominant landscape types in the study period,the connectivity of each levels of desertification types also decreased.
