摘要:

通过对高邮湖北部区域各理化指标测定和浮游植物定性、定量调查,并采用综合营养状态指数、单因素生物指标和Margalef生物多样性指数对高邮湖营养化程度进行评价。结果显示:高邮湖pH平均值为866,溶解氧平均值为73 mg/L,总氮平均值为102 mg/L,总磷平均值为0051 mg/L,CODMn平均值为961 mg/L,叶绿素a平均值为1038 μg/L,透明度平均值为069 m。高邮湖共有浮游植物8门23科38属66种,其中绿藻门27种,占全部种类的4091%;蓝藻门16种,占全部种类的2424%;硅藻门9种,占全部种类的1364%;裸藻门6种,占全部种类的909%。浮游植物细胞密度值为1940×106 ind./L,生物量483 mg/L。高邮湖综合营养状态指数为5114~6053,浮游植物群落以绿藻、蓝藻为主,Margalef生物多样性指数为1528,说明高邮湖处于轻度富营养化状态,同时有中度富营养化的趋势。〖

Abstract:

The water quality and the structure and amount of algae phytoplankton in Lake Gaoyou were investigated and the trophic status was determined by comprehensive eutrophication state index,singlefactor phytoplankton index and Margalef index.The results showed pH average was 866,DO average was 73 mg/L,TN average was 1.02 mg/L,TP average was 0051 mg/L,CODMn average was 961 mg/L,Chla average was 1038 ug/L,SD average was 0.69 m.66 species belonged to 38 genera,23 families,8 phyla were found in Lake Gaoyou,of which 27 species belong to Chlorphyta,16 species belong to of Cyanophyta,9 species belong to Bacillariophyta and 6 species belong to Euglenophyta,and  the percentage of them were 4091%,2424%,1364% and 909%.The average density and biomass of phytoplankton were 1940×106 ind./L and 483 mg/L.The comprehensive nutrition state index was between 5114 and 6053.The phytoplankton community structure was of greenblue agale type and Margalef index was 1528.All the features indicated that the lake can be regarded as light eutrophication and there was the tendency of middle eutrophication.〖 〖W
