| To evaluate the levels of water pollution of the Haihe River basin and provide basic data for river pollution treatment, the biodiversity of zooplankton and analysis of water in 203 locations of the eight river systems in Haihe River basin were investigated in 2009.

In Heilonggang River system, 125 species of zooplankton belonging to 98 genera were found. The rotifer accounted for 44%; the protozoa accounted for 41.60%; the cladocera and copepods accounted for 8.80% and 5.60% respectively. In Zhangweinan River system,160 species of zooplankton belonging to 122 genera were found. The protozoa accounted for 45.63%; the rotifer accounted for 40.63%; the cladocera and copepods accounted for 9.38% and 4.38% respectively.In Tuhai River and Majia River system,147 species of zooplankton belonging to 111 genera were found. The protozoa accounted for 48.98%; the rotifer accounted for 34.69%; the cladocera and copepods accounted for 10.89% and 5.44% respectively.In Daqing River system,172 species of zooplankton belonging to 103 genera were found. The protozoa accounted for 49.42%; the rotifer accounted for 34.30%; the cladocera and copepods accounted for 12.21% and 4.07% respectively.In Beisanhe River system,211 species of zooplankton belonging to 124 genera were found. The protozoa accounted for 43.60%; the rotifer accounted for 34.12%; the cladocera and copepods accounted for 18.01% and 4.27% respectively.2. Biological evaluation is made with three diversity indices, that is, Shannon-Wiener index, Simpson index and evenness index. In Yongding River system, the middle reach of Yongding River and the Beijing Drainage River were lightly polluted, while the Hunhe River and the middle and lower reaches of the Sanggan River were heavily polluted, upstream of Yongding River and Dongyang River were severely polluted. In Luanhe River system, the lower reach of the Luanhe River was lightly polluted, while the lower reach of the Qinglong River, the middle and lower reaches of the Luanhe River and the middle reach of Wulie River were moderately polluted, and then the middle reach of the Qinglong River, the lower reach of the Wulie River and the upper reach of the Luanhe River were heavily or severely polluted. In Ziya River system, the Fuyang New River, Fuyang River and its tributaries were lightly or moderately polluted while the upper and middle reaches of the Hutuo River, Wendu River, Liulin River and Gantao River were severely polluted. In Heilonggang River system, Canglangqu River, Nanpai River, Nanyun River, Heilonggang River, Weiyun River and FudongpaiRiver were lightly polluted, while Weixiaoyun River was heavily polluted and Zhizhang River was moderately polluted. In Zhangweinan River system, the middle reach of the Anyang River, Zhangwu and Nanhai reservoir, the upper reach of the Tang River, the upper reach of the Wei River and upstream of the Weiyun River were lightly polluted, while the upper and middle reaches of Wei River, Dasha River, Qi River, the middle reach of the Zhang River and Yuecheng reservoir were moderately polluted, and then the upstream of Zhang River was heavily polluted. In Tuhai and Majia River system, the Majia River and the Tuhai River were lightly of moderately polluted while the lower reach of Zhangwei New River was heavily polluted. In Daqing River system, the lower reach of the Ziya New River and the Ziya River, the Duliujian River, the Qingshui River, the Juma River, the Baigou River and the upper reach of the Daqing River were lightly polluted, while the Xiaobai River, the Dasha River, the Yishui River and the upstream of Tang River were heavily or severely polluted. In Beisanhe River system, the Yongding New River, the Chaobai New River, the Huai River, the Wenyu River, the Qinglongwan River, the Beiyun River and its tributaries, the lower reach of the Chaobai River, the Niumutun River, the upstream of Chao River and the Ming Tombs Reservoir were lightly polluted, while the Jiyun River, the Huanxiang River, the middle reach of the Bai River, the Zhou River and the Sha River were moderately polluted, and then the Qingshui River, the lower reaches of Bai River and the Chao River were heavily or severely polluted.3. The results of factor analysis and cluster analysis indicate that the upper reaches of Yongding River, Sanggan River, Yanghe River are seriously polluted, the middle and lower reaches of Yongding River and Liangshui, Beijing blowdown River are moderately polluted; Qing Long River of Luan river system and the upper reaches of Luan River are clean or lightly polluted. Wulie River, the middle and lower reaches of Luanhe River are lightly or moderately polluted; The middle reaches of Hutuo of Ziya River system and its tributaries are lightly or moderately polluted, and Fuyang River, Fuyang New River, Jiao River suffer relatively serious pollution; Fudongpai River in Heilonggang canal East River System and the upper row of Zhang River suffer heavy to severe pollution, the lower reaches of Heilonggang river area suffer severe eutrophication, and other polluted rivers belong to mild to moderate pollution type; Zhang, Wei, South Canal water suffer pollution to a lesser extent, lightly or moderately polluted, Wei River tributaries Anyang River and upstream of the Zhangwunanhai suffer moderate degree of eutrophication in water reservoirs, belonging to moderate pollution type, Weihe River main stream and its tributary Tang river belong to a serious type of pollution or heavier; Tuhaimajia River system, except the river reaches through the town of Mi in Ling county of Dezhou city, the rest were seriously polluted; Daqing River upstream, Juma, Yishui River, Dasha Rver and Tang River are mildly or moderate polluted, Ziya River downstream, Ziya New River, Qingshui river water and Duliujian River reach have moderate to severe river pollution; In the Beisan River System, the water quality of White River water, Chao River, Qingshui River are clean or mildly polluted, the Huai River was polluted with mild to moderate degree, Chaobai River main stream belongs to moderate to the heavy pollution type; North Canal is moderately polluted; Ji Canal shows that, water quality of main stream gets worse than the tributaries; It mainly shows that there is more serious organic pollution in main stream. |
