The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.

Based on field experiment and measure data, ecological characteristics of soil water in different fencing sandy land in arid desert area and vegetation restoration effect of soil water variation in fencing sandy land were analyzed. In representation of Artemisa arenaria DC population, observing and researching vegetable restoration effect of soil water variation in fencing sandy land. The results indicate as follow:(1)With the vegetation development constantly in fencing sandy land, soil water utilization of vegetation increased. It made soil water content and soil water storage reduced with the increase of fencing time in sandy land.
