摘要

Traditional water resources assessment methods can't effectively reflect spatial changes of the watershed's Land Use and Cover Change (LUCC) and the water spatial distribution. Despite numerous efforts to develop methods for water resources assessment, few assessment methods for larges scale river basin are based on distributed hydrology model yet. Haihe River Basin's SWAT model has been developed for the water resources assessment after data collection, data preprocessing, watershed delineation and division. The whole Haihe River basin whose area is 3.18 × 10~5km~2 is spatially delineated as 211 sub-basins, and each sub-basin is divided into certain hydrology response units (HRUs) according to different land use type and the soil distribution type. The whole basin finally forms 1483 HRUs, 17 outlets into sea, 28 large type reservoirs and 960 basic computing units and generates the about 4000 model parameters files. And then, Haihe River basin integrated water resources assessment system based on SWAT (IWRAS-SWAT) is presented. Lastly, the parameters' calibration, verification and sensitivity analysis are carried out, and many typical stations are selected to carry out the verification and analysis to the simulation results by using hydrometeorology series' data and surface conditions' spatial data from 1995 to 2002. The preliminary results of simulation and water resources assessment are shown that water resources assessment based on distributed hydrology model is an operational and practical method for water resources assessment of large scale watershed.
