Research on Simulation of Water Quantity in Shexian County Based on Improved SWAT Models

摘要

Based on the improved SWAT model, with 2000-2006 rain and meteorologic data, the Shexian distributed model is developed based on the soil map, water conservancy, land use from the remote sensing and agriculture management information of Shexian county, Hebei province.The model is calibrated with remote sensing evapotranspiration(ET) and observed data of the Kuangmenkou hydrologic station. The water quantity of Shexian is simulated and analyzed. The compare between the simulation result and the observed data shows the simulated data is accordant with observed data. The research result is helpful to the further application of SWAT in county level water resource and water environment integrated management plan(IWEMP).
