西安理工大学西北水资源与环境生态教育部重点实验室，西安 710048 ）摘要：为了开展植被恢复试验，对干热河谷土壤水分的动态变化规律进行初步研究。

Considering the difference of runoff characteristics on different underlying surface in the area of plain tidal river network, four kinds of surface is divided,namely, waters paddy field-, dry land and central urbanized area,and suitable method is adopted separately in each surface to simulate runoff process. Xinanjiang Model usually applicable for mountain areas is introduced to river network area, furthermore, the paper researches runoff calculation of central urbanized area, the underlying surface is divided into pervious and imperviousness areas.In perviousness areas, Hoton Infiltration formula and corresponding spatial infiltration rate curve are used to establish the relationship between infiltration rate and soil moisture in order to decide the infiltration. According to practical situation.

根据平原河网区城市下垫面产汇流方式的不同，分成水面、水田、旱地、城镇四类，分别采用相对应的产流汇流计算方法，将适用于山丘区的新安江模型引入到平原河网区城市，同时对于城镇这类下垫面，从下渗角度考虑，划分成透水和不透水两种类型，根据霍顿下渗公式和下渗率空间分布曲线，建立下渗率和土壤含水量的关系，进而研制出城镇透水面的产流计算方法，城镇汇流根据实际情况可结合城市管道排水计算。

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.
