【摘要】 我国五大淡水湖之一的巢湖 ,目前正面临水质污染、富营养化、泥沙淤积和水旱灾害四大危机。为加强生态环境保护和探讨湖泊资源的可持续利用 ,本文通过分析影响巢湖水环境生态效应的因素 ,利用统计模型 ,对巢湖 COD和磷浓度的削减量进行预测 ;利用水沙模型 ,对巢湖的泥沙淤积量进行淤测。实际应用证明 ,这两个模型用于预测 COD、磷浓度的削减量和泥沙淤积量是可行的。更多还原

【Abstract】 The CHAOHU lake ,as one of the five biggest freshwater lakes in China, is faced with four crises which are pollution, supernutrition, siltation and drought. In order to protect environment and keep the sustainable utilization of the lake resources, the paper predicts the reduction of COD and phosphoric concentration by statistical model and predicts the silt content of the CHAOHU lake by water and silt model after analysis the factors which affect the environment of the CHAOHU lake. And it is proved that the two models are feasible to predict COD,phosphoric concentration and silt content.更多还原
