摘　　要： 以典型三角洲工业城市东莞市第一次全国污染源普查成果为数据基础,分析了2010年东莞市废污水入河量的空间分布特征及其影响因素。分析结果表明,东莞市各镇街废污水入河量分布明显不均匀,经济发达镇街及东江河网区镇街废污水入河量非常集中,总体上下游地区大于上游地区;GDP、污染行业、地理位置是主要影响因素。同时发现,河网区镇街单位GDP工业废水入河量大于非河网区,其根本原因在于,河网区镇街水资源丰沛,取水排污方便,污染行业集中,其用水方式极为粗放,经济增长的污染代价巨大。 Based on the first national census data of pollution sources of Dongguan City,a typical industrial city in delta area,the spatial distribution characteristics of sewage entering rivers and its influential factors of Dongguan City in 2010 are analyzed.The study shows that the sewage discharge from the towns of Dongguan City is distributed unevenly;the sewage discharges from economically developed towns and the towns in Dongjiang River network area are very concentrated and have a general tendency of larger sewage discharge in downstream area;the main influential factors are GDP,pollution industry and geographic location.In the meantime,the unit GDP sewage discharge in river network area is larger than that in non-river network area,showing that the economy in river network area developed at the cost of environment.The basic causes of severe pollution in river network area are rich water resources,convenient water taking condition,concentrated pollution industries,resulting in extensive water use and severe industrial sewage pollution.
