研究了湛江东海岛2口凡纳滨对虾高位养殖虾池水体主要理化因子在养殖过程中的动态变化及其相互关系,并用营养状态质量法对该养殖场的水质状况进行评价.试验结果表明,养殖过程水体中DO、pH、温度和盐度波动较小、变化平缓,而COD、DOC、营养盐和叶绿素a的含量随养殖过程而上升.主要理化因子之间的相关关系复杂,但叶绿素a与营养盐之间存在显著的正相关关系.在养殖中后期,表征富营养化的NQI值大幅度升高,水体富营养化程度严重.

The dynamic changes and correlation in main physicochemical factors in water were studied in white leg shrimp Litopenaeus vannamei ponds in Donghaidao of Zhanjiang, and the NQI was adopted to estimate the quality of water in the ponds. The results indicated that DO, pH, temperature and salinity fluctuated gently, but the concentration of COD, DOC, nutrient and chl-a increased relevant to culture. The correlation was complicated among the main physicochemical factors while there was a significantly positive correlation between chll_a and nutrients. The NQI value showed that the eutrophication increased rapidly in the middle and late of culture period, implying serious eutrophication in the shrimp ponds.
