应用分布式水文模型优化黑龙港及运东平原农田灌溉制度Ⅰ:模型参数的率定验证
Application of distributed hydrological model for optimizing irrigation regime in Heilong-gang and Yundong plain I. model calibration and validation
摘要
Abstract
The Heilonggang-Yundong plain is one of the most important food production region in the Hat- he River basin, but it is severe deficient in water resources. In this paper, in order to optimize irrigation schedule, firstly using Shuffled Complex Evolution (SCE-UA) to calibrate the crop parameter of Soil and Water Assessment Tool (SWAT) in Wuqiao Station and Quzhou Station. Secondly, based on the actual evapotranspiration (ET.) which calculated by remote sensing (RS), are the sensitivity of parameters analy- sis and the most sensitive parameters are selected and then use "Sequential Uncertainty Fitting Algorithm" (SUFI-2) to optimize the parameters. Thirdly, under the consideration of uncertainty of the model, the yield of long term simulation for winter wheat and summer maize rotation system is validate. The results of calibration and validation laid the foundation for the further research on water product function and irriga- tion regime optimization.关键词
