摘要:
根据 1999年冬季对固城湖生物资源现状的调查,分析了固城湖冬季生物资源的群落织成和结构特征,探讨了固城湖水质的演变趋势和湖泊养殖能力.结果表明,固城湖水质虽达到国家Ⅲ类饮用水标准,但固城湖水质已呈现明显的富营养化趋势,当前固城湖可自然提供的渔产潜力约为81.4×104kg,为保障固城湖渔业生产和水资源质量,应做好水生植物资源改良和保护,调整湖泊渔业结构.

Abstract:
Based on the investigations of bilogical resources on Dec..1999 in winter Gucheng Lake Jiangsu Province, the biomass abundance of zooplankton, hydrophyte as well as compositions and community structures are analysed.Moreover the changing tendency in 1990-1999 and the culturing capacity of fishery in Gucheng Lake are discussed.Although the water quality of Gucheng Lake belongs to Grade 3 according to national surface water quality standards for drinking water,yet the lake water is under eutrophication gradually,especially in recent years.The potential fishery yields of Gucheng Lake is estimated to be 0.8 million kilogram.Some measures must be taken to prevent the aquatic environment from further deterioration so that the biological resources be protected and utilized in a sustainable way.
Key words:  Gucheng Lake  biological resources  environmental quality
