基于原位土壤观测的SWAT关键参数及模拟优化分析
Optimization of Key Parameters for SWAT Model Based on Field Soil Observation
摘要
Abstract
In this study, onsite observed soil data were used to calculate the values of five key soil parameters by physically based mathemat-ical formula and model in the Abujiao River basin in Northeastern China. Then two simulations of agricultural diffuse pollution were per-formed with SWAT(Soil and Water Assessment Tool)model. One model simulation was based on calibrated parameter values, while the oth-er simulation was based on calculated parameter values. There were considerable differences between calibrated parameter values and cal-culated ones for SOL_AWC, SOL_K, SOL_BD and USLE_K, but no significant difference found for SOL_CRK. However, two simulations showed no significant difference in the agricultural diffuse loads. They also had similar dynamics both on yearly and monthly scales. There-fore, SWAT model based on observed soil data could be a good simulation on agricultural diffuse pollution, especially in watersheds without monitoring data on hydrology and water quality.关键词
