With taking many measures of combating land desertification in the past decades, the distinct effects have been achieved in Yulin Prefecture of Shaanxi Province in northwestern China. The objective of this study was to monitor and analyze the dynamic changes of desertification in the regions in the 14 years from 1986 to 2000 using remote sensing and(More)
In this paper, land use maps in the two dates, 1986 and 2000, were acquired by visual interpretation from digital Landsat TM images with the help of MGE and ARC/INFO 7.1. Based on spatial analysis and statistical analysis in GIS, the spatialtemporal changes of land use from 1986 to 2000 in the region were obtained and analyzed. Firstly, the transition(More)
