石家庄市民心河水质预测分析

Forecast and analysis of the water quality of Minxin River in Shijiazhuang

通过对石家庄市民心河沿线设立不同的监测点，选择对民心河景观水体影响较大的BOD5、氨氮、高锰酸钾等指标进行长期的监测．并根据2001—2006年水质监测数据，运用GM（1，1）模型建立了民心河水质预测模型，预测了民心河水质变化的趋势和规律，为民心河的治理和管理提供依据。

Observation stations along the Minxin River, Shijiazhuang city, were set up for the monitoring of the water quality according to the important indices of BOD5 , ammonia nitrogen, potassium permanganate, etc. Based on the data achieved from 2001 to 2006, a forecasting model for the river water quality using the model of GM（ 1, 1） was developed. And the variation trend and pattern of the water quality was forecasted by using the model, which will provide a basis for the water quality control.
