摘　　要：1999年10月至2001年10月对杏林湾水库进行了水质理化特性的周年季节调查,结果表明:水库平均水温20.5℃,pH值平均为7.8,呈微碱性,透明度为36.8cm,碱度平均为43.63mg·L-1,溶氧为9.86mg·L-1,水中磷为0.10mg·L-1,无机氮为2.43mg·L-1,化学耗氧量为8.48mg·L-1.多数理化因子周年中出现明显的季节变化,在平面上也有差异,但差异不明显.杏林湾水库水质的化学耗氧、氨态氮和亚硝态氮含量超过备用水源(为Ⅱ类水)的标准.This paper summarizes water physicochemical characteristics from October,1999 to April,2001 in Xinglin Bay Reservoir.The results showed:Water temperature was 20.5℃,secchi transparency was 36.8cm,pH value was 7.86,alkalinity was 43.6mg·L-1,dissolved oxygen was 9.86mg·L-1,chemical oxygen demand was 8.48mg·L-1.The contents of nitrogen was 2.43mg·L-1,total phosphorus was 0.10mg·L-1 in Xinglin Bay Reseroir.There were marked seasonal changes in most physicochemical components in the water.The differences of most physicochemical components were inconspicuous in horizontal and distributions.The content of COD ,NH4-N and NO2-N in water of Xinglin Bay Reseroir is more than that of the Ⅱ class water.
