| Abstract: | Detail interpretation of TM satellite image in 1988 and 1999 for the Anning River basin by the use of remote sensing image in combination with field investigation and comprehensive assessment by the use of vegetation index and GIS space analysis as well as analysis of dynamic change in ecologic environment and soil erosion during the past decade provide scientific basis for reconstruction of ecologic barrier in the upper reaches of the Yangtze River and for ecologic environmental protection in the Anning River basin. |
