在黑龙江省松花江入境断面（肇源断面）内选择监测．量，对不同月份的水体中化学需氧量、总磷、氨氮和粪大肠菌群数量的动态监测。结果表明，不同时期河流中的化学需氧量、总磷、氨氮和粪大肠菌群数量变化趋势不同，在夏季时化学需氧量和总磷的浓度较高，而氨氮的浓度在1月份较高，粪大肠菌群数量在8月份最大。

The songhua fiver in heilongjiang province entry section （zhaoyuan section） choose within monito- ring stations. We dynamic monitoring water in chemical oxygen demand （cod） , the total phosphorus, ammonia nitrogen and fecal coliform bacteria number in different months. Results show that different period of river chemical oxygen demand （cod） , the total, phosphorus, ammonia nitrogen and fecal coliform bacteria quantity change trend is different. In the summer chemical oxygen demand （cod） and total p high concentration. The concentrations of ammonia nitrogen in January is the highest. Fecal coliform bacteria number in August is the largest.
