摘要

Via field investigation and data collection in the Longgang River basin, input data for SWAT watershed hydrological model were obtained. Sub-basin s boundary was calculated and divided by spatial analysis, and meteorological input conditions were used to drive example simulation, such as rainfall and temperature. Watershed database was established in the backend of server, and GIS resources were provided by issuing GIS service, and WebGIS platform was developed in front of the browser. Executive file was generated by compiling source file of SWAT model, and input file and parameter modification, model operation and calculation, and result extraction and transmission were conducted via PHP, to realize the coupling of SWAT model with WebGIS platform, and enhance display effects of model input conditions and simulation results.
