Dynamic Changes of Desertification Landscape Pattern at Yushenfu Mining Area in Yulin City of Shaanxi Province
摘要
Abstract
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.关键词
