摘　　要：本文简要报道了海口地区养鱼池的水深、水温、透明度、总硬度、酸碱度(pH),溶解氧,有机物耗氧量及总氮,总磷、硅等主要物理和化学因子的周年调查结果。海口地区养鱼池水深平均为0.16—1.15m,水温21.5—36.0℃,水的总硬度0.49—2.24mmol/L,pH5.6—7.5,透明度18.8—39.3cm,溶解氧含量5.98—9.66mgO_2/L,有机物耗氧量10.7—20.9mgO_2/L,总氮含量2.58—7.92mgN/L,总磷含量0.038—0.169mgP/L,N/P比值为35.69,硅含量1.27—10.96mgSiO_2/L。针对海口地区养鱼池的上述特点,提出了改造建议。This paper describes the results of annual investigation on the physical and chemical index of fishponds in the Hai Kou area. The results are as follows. depth of the fishponds 0.61～1. 15m water temperature 21. 5～36. 0℃ total hardness of the water 0. 49～2. 24m mol/L pH 5. 6～7. 5 transparency 18. 8～39. 3cm dissolved oxygen content 5. 98～9. 66mg O_2/L oxygen consumption by organic matter 10. 7～20. 9 mg O_2/L total amount of N 2. 58～7. 92mg N/L total amount of P 0. 038～0. 169mg P/L ratio of N; P 35. 69 amount of silicate (sio2) 1.27～10.96mg/L In the light of the aforementioned results, proposals for the resorm of fishponds in the Hai Kou area has been put forward in this papel.
