【摘要】 结合近年来广州花地河水质监测的数据资料,针对水体中透明度、叶绿素a、浮游藻类和底栖动物等方面进行生态调查及对比分析。结果表明,花地河浮游藻类以耐污习性的蓝藻为优势种群,呈现了暴发生长的情况,同时底栖动物中耐污的水丝蚓的密度也在逐年不断增长,水体理化因子中,总氮和氨氮的含量亦在逐年增高,花地河水体的有机污染十分严重。提出了花地河自身净化能力已不能解决该河的重度污染问题,唯有政府有关部门的重视,进行全面的环境综合治理,才是解决问题的最好出路,并提出了运用生态学原理及跨境合作控制花地河污染的构想和建议。更多还原

【Abstract】 According to water quality pollution level of Huadi River in Guanazhou,we analyzed the status of SD,chlorophyll a,phytoplankton and zoobenthos in the waterbody.The results indicated that the dominant phytoplankton were cyanophytes which were contaminative-resistant habit and proliferated in the waters.The density of Limnodrilus sp.contaminative-resistant of zoobenthos increased yearly,and the concentration of TP and TN also increased year after year.Besides,the pollution resulted from organic matter became more serious.The self-purification capacity of Huadi River can’t treat the pollution by itself,so related government departments should attach importance to integrated environmental control.This paper pertinently advised that we should take effective measures which combine ecological theories and multi-side co-operation to control the pollution in Huadi River.更多还原
