Description

Desertification monitoring in Naiman-Qi, Inner Mongolia, China in the 1960's was conducted using satellite imagery of reconnaissance satellite of USA, CORONA. Imagery observed on 12th September 1961 and on 30th November 1970 were used in this study. The map developed by Chinese Academy of Science was utilized for supervised classification. The result clarified that in the north west part of the study area, desertification had markedly processed between 1961 and the 1990's. Except the north west area and river terrace along the Jiorai River where desertification almost stopped after the 1980's by artificial forestation. Therefore no much new desertified area had emerged in the northern part of Naiman-Qi. Remedies of desertification recommended to concentrate into north west area with enough care taken to river terrace along the Jiorai River after the series of studies completed by this study.
