In this paper, the Ordos Plateau in China was selected as the research region and a quantitative method for desertification assessment was developed by using Landsat MSS and TM/ETM+ data on a regional scale. In this method, NDVI, MSDI and land surface albedo were selected as assessment indicators of desertification to represent land surface conditions from vegetation biomass, landscape pattern and micrometeorology. Based on considering the effects of vegetation type and time of images acquired on assessment indictors, assessing rule sets were built and a decision tree approach was used to assess desertification of Ordos Plateau in 1980, 1990 and 2000. The average overall accuracy of three periods was higher than 90%. The results showed that although some local places of Ordos Plateau experienced an expanding trend of desertification, the trend of desertification of Ordos Plateau was an overall decrease in from 1980 to 2000. By analyzing the causes of desertification processes, it was found that climate change could benefit for the reversion of desertification from 1980 to 1990 at a regional scale and human activities might explain the expansion of desertification in this period; however human conservation activities were the main driving factor that induced the reversion of desertification from 1990 to 2000., 2009, 卷号: 9, 期号: 3, 页码: 1738-1753 作者:  Zhuang, Dafang(庄大方);  Qiu, Dongsheng 收藏  |  浏览/下载：269/70  |  提交时间：2011/06/10 Desertification  quantitative assessment  Landsat  Ordos Plateau   The study on the geometrical homogenization of discrete global grid model EI期刊论文 2007 作者:  Qiu Dongsheng;  Yuan Wen;  Zhuang Dafang 收藏  |  浏览/下载：10/0  |  提交时间：2012/06/11 The unstructured data sharing system for natural resources and environment science data of the Chinese academy of science EI期刊论文 2007 作者:  Dongsheng Qiu;  Jiyuan Liu;  Wen Yuan;  Dafang Zhuang 收藏  |  浏览/下载：27/0  |  提交时间：2012/06/11 Information management  Metadata  Servers  User interfaces
