摘 要：
2004年5月、7月、9月和12月对大力加湖鲟鱼放养场水化学特征进行了调查,结果表明：大力加湖鲟鱼放养场水质良好,透明度变幅在45～90cm,pH值变幅在6.69～8.72,水呈中性。水型属重碳酸盐类,钙组Ⅰ型(C_Ⅰ~(ca))软水。水中主要营养元素含量,总氮含量较高平均为1.63 mg/L,磷酸盐含量较低平均为0.0339 mg/L。离子含量以冬季最高104.52 mg/L,春季最低51.64 mg/L。水中离子含量高低次序为HCO_3~-＞Ca~(2+)＞Cl~-＞Mg~2＞Na~(?)+K~+。探讨了水体的的营养类型和利用。

摘 要：
The Physico-chemical characteristics and Seasonal changes of Dlijia Lake were studied from May to December 2004.The results are as follows.Dlijia Lake has good wa- ter quality,transparency changes 45～90cm,pH value changes 6.69～8.72,and the water type belongs to C_Ⅰ~c a and soft water.The contents of major nutrient elements were high,the contents of TN in water was 1.63 mg/L,and the contents of phosphate was lower (0.0339 mg/L).The contents of hydronium were high in winter(104.52 mg/L),and the contents of hydronium was lower in spring(51.64 mg/L).The contents of hydronium were HCO_3~-＞Ca~(2+)＞Cl~-＞Mg~(2+)＞Na~(+s)+K~+ in water.The water style of nutrient was also dis- cussed in this paper.
