宿鸭湖水库是河南省平原区的一座大型水库。面积113.33 Km~2,平均水深1.4m、透明度11cm。从1986年1～11月对该库浮游生物采样调查,共采到浮游植物8门、27科、44属、其中绿藻门有17属、蓝藻门有10属、硅藻门有8属、黄藻门1属1个种类;浮游动物66属,其中原生动物13种,轮虫28种,枝角类18种,桡足类7种。浮游植物生物量平均1.08mg/L,其中蓝藻占15.8×10~(-2),隐藻占27.4×10~(-2),甲藻占1.6×10~(-2),金藻占4.5×10~(-2),硅藻占16.9×10~(-2),裸藻占35.6×10~(-2),绿藻占12.3×10~(-2)。浮游动物量平均3.60 mg/L,其中原生动物占2.89×10~(-2),轮虫占3.36×10~(-2),枝角类占77.98×10~(-2),桡足类占15.77×10~(-2)。初步探讨了浮游植物,浮游动物变化的若干规律。
Suya Lake Reservoir is a large reservoir in the plain area of Henan Province. Area of 113.33 Km ~ 2, the average depth of 1.4m, transparency 11cm. From January to November 1986, a total of 8 phytoplankton species, 27 families and 44 genera were collected from January to November in 1986 in which the phytoplankton were sampled. Among them, there were 17 genera of Chlorophyta, 10 genera of Cyanophyta, 8 genera of Bacillariophyta, There are 1 species of the genus Xanthophyll, 66 species of zooplankton, including 13 species of protozoa, 28 species of rotifer, 18 species of cladocerans and 7 species of copepods. The average biomass of phytoplankton was 1.08 mg / L, of which cyanobacteria accounted for 15.8 × 10 -2, algae accounted for 27.4 × 10 -2, dinoflagellates accounted for 1.6 × 10 -2, × 10 -2, diatom accounted for 16.9 × 10 -2, euglena accounted for 35.6 × 10 -2, and green algae accounted for 12.3 × 10 -2. The average amount of zooplankton was 3.60 mg / L, of which protozoan accounted for 2.89 × 10 -2, rotifer accounted for 3.36 × 10 -2, cladodes accounted for 77.98 × 10 -2, Accounting for 15.77 × 10 ~ (-2). Preliminary study of the phytoplankton, zooplankton changes in a number of laws.
