区域污染水体特征和变化规律——以成都市府河黄龙溪段为例

Characteristics and Changing Laws of Regional Water Pollution——Case study at Huanglongxi section of Fuhe River in Chengdu

通过对成都市府河黄龙溪段进行为期1年的监测,分析结果表明府河水体中的TN、NO3--N、NH4+-N、TP和PO+4-P的变化受降雨影响较大,具有明显的季节性。府河水生态系统稳定性较差,各指标波动范围较大;虽然水体污染较为严重,浊度高,但是仍有部分沉水植物存在。府河的主要污染源是城镇生活污水和沿途污水地表径流,严格控制污染源才是解决问题的根本。

The water in Huanglongxi section of Fuhe River was monitored for one year.The data analysis showed that the contents of total nitrogen,nitrate nitrogen,ammonia nitrogen,total phosphorus and phosphate in the river water changed were affedted by rainfall seasonally very much.Stability of the River ecosystem with indexes in large range of fluctuation.In spite of serious water pollution and high turbidity,there were still some spicies of submerged plants survived.The sources of pollution in Fuhe River are domestic sewage and sewage runoff along the river.Strictly control the pollution source is the only way to solve the problem.
