【摘要】 详细介绍了珠江流域云南片区点源及非点源污染负荷排放量及入河量的计算方法,并根据污染控制区的计算结果分析了珠江流域云南片区点源及非点源排放量及入河量分布特征,认为非点源污染物排放量所占的比例明显高于点源,而点源污染物入河量所占的比例明显高于非点源。更多还原

【Abstract】 The calculation method of discharge volume and inflow volume of point and non-point wastewater pollution source of Pearl River in Yunnan is introduced,based on which the distribution characteristics of method of discharge volume and inflow volume of point and non-point wastewater pollution source of Pearl River is shown.The results show that the ration of discharge volume of non-point pollution source is higher greatly than that of point pollution source,however,the ration of inflow volume of point pollution source is higher than that of non-point pollution source.更多还原
