天然河流一维水质模型的研究与改进

Study and Modifacation on Onedimension Water Quality Model in Natural Rivers

分析和研究了在河流污染浓度控制中广泛应用的一维水质模型结构和应用条件．根据总量控制的需要，以河流中瞬时面源排放的一维水质模型为出发点，采用叠加原理和积分法重新推导了连续稳定面源排放的一维水质模型结构，通过实际应用，检验了模型的精确性和实用性，分析比较了总量控制一维水质模型与浓度控制一维水质模型的结构、应用条件。

The construction and applied condition of onedimension water quality model used extensively in concentration control of river pollution is analyzed and studied.According to the demand of total quantity control,lamination principle and integral method are used to calculate the construction of onedimension water quality model.By application in practice,the accuracy and the applicability of the model for total quantity control are tested.The construction,the applied condition,the accuracy and rationality between the onedimension water quality model for total quantity control and the onedimension water quality model for concentration control are compared.
