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。
The water chemical characteristics of sturgeon stocking field in Dagalhu Lake were investigated in May, July, September and December 2004. The results showed that the water quality of sturgeon stocking area in Dali Lake was good and the transparency range was 45 ~ 90cm Value range 6.69 ~ 8.72, the water was neutral. Water type is bicarbonate, calcium group type Ⅰ (C_ Ⅰ ~ (ca)) soft water. The main nutrient elements in water, with a high average total nitrogen content of 1.63 mg / L, a lower average phosphate content of 0.0339 mg / L. The highest ion content was 104.52 mg / L in winter and 51.64 mg / L in spring. The order of ions in water is HCO 3 -> Ca 2 +> Cl -> Mg 2> Na ~ (?) + K ~ +. Discussed the type and utilization of water body nutrition.
