哈尔滨二龙山水库浮游植物及水体污染状况的研究

STUDY ON THE PHYTOPLANKTON AND WATER POLLUTION OF ERLONGSHAN RESERVOIR IN HARBIN

报道了 2 0 0 0年 1月、5月、8月、1 0月四次对哈尔滨市境内的二龙山水库的浮游植物的调查结果。共发现浮游植物 46属 5 5种 ,其中种类最多的是绿藻和硅藻。水库四季的平均浮游藻类数量为 43 8.46万个 /升 ,绿藻占 46 .98%,硅藻占 44.74%,隐藻占 6 .76 %。优势种是平裂藻、小环藻、直链藻、针杆藻、纤维藻、空星藻、十字藻、蹄形藻、栅藻、隐藻等。对 8月份水库及上游河流的水质进行了监测和分析。根据上述结果对水质进行了评价 ,并对二龙山库区的水土保持及可持续性发展进行了探讨。

This paper presents the results of the phytoplankton investigation on Erlongshan Reservoir in Harbin in January, May, August and October 2000. A total of 46 genera and 55 species planktonic samples were observed. The majority of them are Green Algae and Bacillaroiphyta. The average number of plants per liter in water is 4.38×10 6. Chlorophyta is 46.98% and Bacillaroiphyta is 44.74%. The dominant genera and species are Merismopedia elegans, Cyclotella sp, Melosira granulata, Synedra sp, Ankistrodesmus sp, Coelastrum microporum, Crucigenia sp, Krichneriella lunaris, Scenedesmus sp, Cryptomonas sp. In Augest, the monitor and analysis of the reservoir and its upper reaches of river were made. On the above results, we evaluate the water quality and discuss the water and soil conservation as well as the sustainable development of the reservoir.
