Wind erosion is one of the major environmental problems in semi-arid and arid regions. Here we established a transect from northwest (Tariat, Mongolia) to southeast (Xilingol, Inner Mongolia of China) across the Mongolian Plateau, and estimated the soil wind erosion gradient patterns by using the 137Cs tracing technique. In the Mongolia section, the wind erosion rate increased gradually with vegetation...
Based on the RS and GIS methods, Siping city is selected as a study case with four remote sensing images in 25 years. Indices of urban morphology such as fractal dimension and compactness are employed to research the characteristics of urban expansion. Through digital processing and interpreting of the images, the process and characteristics of urban expansion are analysed using urban area change,...
Vegetation spectrum is a very complicated curve caused by its biochemical and biophysical properties. The development of hyperspectral technology makes it possible to obtain a continuous spectral curve from visible to shortwave infrared rather than several isolated broad bands. Inversion of biochemical information from it is an important and practically valuable research. In this paper, we compared...
