| Abstract: | 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. |
