摘　　要： 对凡纳滨对虾高位养殖池水质环境状况进行了研究。结果表明，养殖期间虾池水体透明度前期较高，中后期较低；虾池pH变化在7．89-9．02之间，变化幅度较小。虾池水体悬浮物数量和CODMn随养殖时间延长而持续升高，变化范围分别为18．5—162．3mCL和3．52-14．58mg／L。虾池水体中营养盐各月份波动较大。无机氮的数量变化在0．206—1．621mg/L之间，含量逐渐升高，磷酸盐数量变化在0．009-0．067mg／L之间，含量逐渐下降。水环境中N、P比较高，平均为62．7。养殖水体中后期处于严重富营养化状态。 This paper dealt with the physiochemical traits of the water in the higher-altitude Litopenaeus vannamei cuhure ponds. Results showed that the water transparence was better in the early period of culture than in the middle and later periods; pH value altered in the range of 7.89 to 9.02; the amount of suspended matters in the ponds fluctuated from18.5 to 162.3 mg/L; COD of the pond water altered in the range of the 3.52to 14.58 nag/L, averaging 9.65 mg/L; COD and the amount of suspended matters increased steadily with the cultural time. The amount of inorganic nitrogen altered in the range of 0.206 - 1.621 nag/L, averaging 0.796 mg/L; the amount of the phosphate altered in the range of the 0.009 - 0.067 mg/L, averaging 0.028 mg/L. The amount of nitrogen increased gradually while the amount of phosphate decreased gradually and resulted in a considerable high ratio of N/P （ range 22.1 - 189.3, mean 62.7）. Taken all aspects into accounted, the water quality was in the state of supereutrophication.
