摘　　要：为充分利用龙滩水库的水域，使水面既发挥其养殖功能，又最大限度地保护水体的其他功能，采取化学分析法与物料平衡法联用的估算方法，以养殖过程中物质输入输出的平衡方程间接推算水域环境对投饵网箱养殖容量的限制程度。结果表明：龙滩水库罗甸县茂井镇八达村库湾水体溶解氧、总磷、透明度指标基本处于贫中营养与中营养水环境标准之间，化学需氧量、总氮则达到富营养水环境标准。若全部采用A网箱、B网箱、C网箱模式，龙滩水库罗甸县茂井镇八达村库湾水域的鱼类负载量分别为230．3～276．5 t、364．4～437．4 t和944．4～1133．8 t，C网箱、B网箱的养殖容量分别是A网箱模式的4．1倍和1．6倍，表明不同的网箱养殖模式直接影响水产养殖容纳量的变化。The effect of water quality on carrying capacity in net cage aquaculture was studied by estimation methods of chemical analysis and material balance to develop and protect the aquaculture function and other water function of Longtan reservoir.The results showed that the indexes of dissolved oxygen,total P and transparency were between poor-middle nutrition and middle nutrition environment standard and the indexes of chemical oxygen demand and total N reached the eutrophic water environment standard.The fish capacity of net cage A,B and C aquaculture patterns can be 230.3~276.5 t,364.4~437.4 t and 944.4~1 133.8 t respectively,which indicates that net cage aquaculture pattern has the direct effect on carrying capacity in aquaculture production.
