Modern approach methods of geography, ecology, quantitative analysis, expert integration, remote sensing image analysis and geographical information system were combined to reveal the matters in this paper. The eco-geographical background of the research area and the research work studied by other scholars were comprehensively expatiated. The temporal and spatial variation of precipitation and soil moisture, vegetation and soil distribution, and land use/land cover were compared as well. On the basis of foregoing analysis, the eco-geographical differentiation was discussed. According to principles and indicators, with extension engineering method and integrated analysis, the physical geography boundary between subhumid and semiarid areas were demarcated. By using remote sensing image analysis, wavelet analysis of the perennial precipitation and temperature, and the comparison of temporal and spatial variation of the desertification, this paper accounted for the regional response to global environmental change and suggested the dominant environmental problems.
