Establishment and Application of the Regional Water Balance Analysis Model Based on RS ET Data
Regional water balance analysis is the foundation to guarantee the sustainable use of water resources and the sustainable development of economy. In this paper, the CPSP model was selected as the regional water balance analysis tool in Daxing county based on its calculation principle introduced. The model was validated with runoff data of Integrated Planning of Water resource in Daxing Beijing, RS ET data and monitoring groundwater data, respectively. The calculated runoff data are basically consistent with that in Integrated Planning of Water resource in Daxing Beijing. Meantime, the dynamic variation of Evapotranspiration and groundwater could be simulated well. Basis of this, the current water resources were evaluated for 2004 and 2005, and the water shortage was 0.72×108m3 and 1.80×108m3, respectively.
