摘要
该文以大庆市具有代表性的纳污湖泡──贴不贴泡区地下水污染系统为研究对象。通过对其组成及特征进行分析，提出地下水污染系统可分为局部、浅部和深部污染系统，它是污染质以地下水循环系统为载体，在对流、水动力弥散、吸附解吸和生化反应等的共同作用下形成的。在此处，对流作用对地下水污染系统的形成起至关重要的作用。该研究将为大庆市地下水污染的防治措施的制定提供科学依据。
The thesis takes the representative groundwater pollution system of containing pollution pool - Tiebutie pool district as the object of study in Daqing city. By the analysis of its composition and characteristic, it presents that the groundwater pollution system can be divided into the local, shallow and deep system. It is formed for the pollutants with the groundwater circulating system as the carrier, under the concerted action of convection, hydrodynamic dispersion, adsorption, desorption and biochemical reaction etc. Here, the convection is of vital importance for the formation of groundwater pollution system. This study can provide a scientific basis for formulating the preventive measures of groundwater pollution in Daqing city.
