Abstract: The Zhujiang (Pearl) River Delta is the rapid economic development region in China since the opening and reform door policy was carried out in 1978. Being the rapid development of industry and city, the impact on the aquatic environmental quality was significant. The pollution caused the water quality descended and the ecological system degraded, and also impeded the economic development. The characteristics and problems of the aquatic environment are: the capacity of aquatic environment is large but hasn't been utilized rationally, the water quality is influenced by saline sea water and tide current, the main pollutants are organic matter and the pollution is going heavier, the concentration of pollutants change seasonally. The countermeasures of aquatic environmental protection are:carrying out the environmental functional regionalization and controlling the total amount of pollutant discharge, revising the industrial structure and making a rational industrial arrangement, raising the rate of waste water treatment and making a full assessment of the water conservancy project.
