太湖湖西区河网营养盐输移规律研究

为控制湖西区入湖营养盐量,需要对太湖湖西区河网进行N、P营养盐监测与输移路径模拟.结果显示,宜溧地区营养盐输移规律基本表现为径流输移;常州、金坛地区京杭运河以南河网区虽然日输移路径较为复杂,但是洪期、年输移路径却一致;而京杭运河以北河网营养盐输移规律最为复杂,不仅表现为日输移路径的规律性差,而且洪期、年净输移路径相反....

Study on Nutrients Transportation Rules of the West Lake Area River Nets in Taihu Lake

In order to control nutrients into Taihu Lake from the west lake area, it is necessary to monitor the concentration of N and P nutrients and simulate their transport routes. Monitoring and simulation results showed that nutrients in Yili area perform a runoff transportation; while transportation routes in river nets area south of Changzhou, Jintan and the Jinghang Canal in flood season is consistent with whole year in spite of its complex. But north of the Jinghang Canal the network of rivers nutrient transportation is most complex, not only the regularity of daily transport path is poor , moreover, the net year flux is apposite with the flood flux. With both the mathematical model and monitor method, it expands and widens the information got from monitoring on both space and time, which has a high application value.
