摘要：珠江三角洲地区水环境污染特点表现为：污染物排放量大、类型杂且集中，潜在复合污染出现，跨界污染突出，城市污染依然严重，并呈现出从城市向农村蔓延的区域性污染趋势，加上近几年咸潮入侵加剧，使区域水质型缺水的局面更趋紧张。造成这种污染局面的因素：一方面受控于区域内特殊的河网分布格局，水体径流特征、水资源分配的地区性差异以及海潮入侵等自然因素；另一方面也反映了区域经济发展模式，工业布局和城市规划不
斯文赫定尽合理，环境基础设施滞后，环境意识淡薄，经济发展与环境保护不协调等人为因素所致。

Abstract: In Pearl River Delta region,water environmental contamination featured big amount and mixed types and centralization of pollutant discharge with latent combined po
llutants,striding boundary pollution,severe municipal pollution,the trend of regional pollution being extended from cities to rural area,infall of salty tide in recent years.As a result,the unwatered complexion was hastened due to bad water quality.The factors of water environmental contamination were analyzed as the natural factors including especial hydrographic net distributed pattern,water body runoff characteristic,water resource distributive regional difference,infall of ocean tide,and so forth; the artificial factors as inconsequence of economic development mode and distribution of industry and cities planning,lagging environmental infrastructure,indifferency of environmental consciousness,dissonance of economic development and environmental protection.
