摘　　要：从地下水的污染和咸化、土壤的污染和盐碱化、海水的污染和富营养化等3个方面研究了高位池养殖污染的渗透规律,并确定相应的数学模型.地下水污染和咸化以民用水井中的Cl-含量来表征,Cl-检出量随水井与高位池距离的增大而呈递减变化规律;土壤的污染和盐碱化以含盐量来表征,含盐量随农田与高位池距离的增大而呈梯度递减变化规律;海水污染和富营养化以COD、TP来表征,COD、TP浓度与海水深度呈递减变化规律.The osmotic law of polluted waste-water from upland aquaculture pond was studied from the following aspects,i.e.the pollution and salinity of underground water,the pollution and salinization of soil,the pollution and eutrophication of seawater,and the corresponding mathematic model was presented.It indicated that when the Cl^- content of well water used by people was taken as a factor for marking the pollution and salinity of underground water,the detected content of Cl^- showed a decreasing law with the increasing of the distance between well and upland aquaculture pond; when the salt content was taken as a factor for marking the pollution and salinization of soil,it also showed a decreasing law with the increasing of the distance between farmland and upland aquaculture pond;when the COD/TP were taken as the factors for marking the pollution and euutrophication of sea water,Their concentrations showed a decreasing law with the depth of sea water.
