Model of Water Resources in Small Watershed of Jialingjiang Typic Hilly Areas

Canpopy interception, evapotranspiration, runoff yield and concentration constitute primary hydrologic processes, which mathematic modeling contributes an important way to study hydrologic regularity. Jialingjiang hilly areas is an important ecological barriers and economic zone of Yangtyz river. In this paper, a tipical small watershed-Lizixi basin is selected to simulate main hydrology processes of Jialingjiang hilly small watershed. Results of model show that the model uncertainty factor meets the precision requirements of B and relative error is below 15%, which indicates that the model reflects the actual hydrologic process basically and the model is effective.
