摘　　要：水产养殖造成的水体富营养化不仅导致有机质增加,而且致使很多水体理化参数发生变化,包括水中溶解氧下降、沉积物中有机质和硫酸盐、硫化氢的增加、pH值的下降、生物和微生物群落的破坏等.然而,目前国内外在这方面的研究极少,水产养殖对水体汞甲基化的影响尚不清楚,对其进行深入的研究,并提出合理利用和开发水资源的科学建议具有重要的现实意义.Aquaculture can lead to eutriophication and l-llgh orgamc matter in aquatic ~y^tv , multipile physical and chemical water paramates will change such as dissolve oxgen and pH decrease, sufide （sulfate） and organic matter increase in sediment, and destroying biological community composition, which affact by using the fish pharmaceutical as well excreta input. The efflunce on methylation of mercury in aqautic system from aquaculture has not well understanding, and few reseach is done till now. Therefore, it is very necessary for reasonablly utilizing and developing reservoir resources in future management.
