摘  要:
2011年8月—2012年7月对三都澳四个水产养殖点的营养盐(N、P)、溶解氧(DO)、化学需氧量(COD)、pH值进行了分析,结果表明,无机溶解氮(DIN)组成结构在春、秋、冬季节中主要以NO3-N为主,其次为NH4-N和NO2-N。夏季营养盐结构,NO3-N所占比例明显减低,NO2-N所占比例超过NH4-N。营养盐NO3-N浓度的周年变化为:冬季>秋季>春季>夏季;NO2-N的浓度为:夏季>秋季>春季>冬季;NH4-N浓度:夏、秋偏低,春、冬较高;PO4-P的浓度:冬季>秋季>夏季>春季。水体中DO浓度的周年变化为:冬季=春季>秋季=夏季。pH变化的周年变化为:春季>冬季>夏季>秋季。三都澳四个养殖点周年属于中度营养状态。

摘  要:
According to the analysis of the nutrients(N,P),dissolved oxygen(DO),chemical oxygen demand(COD)and pH value in four aquaculture points in Sandu'ao from August 2011 to July 2012,we found that the mainly inorganic composition of the dissolved nitrogen(DIN)is NO3-N in the spring,autumn and winter,followed by NH4-N and NO2-N.Nutrient structure changed in the summer,the proportion of the NO3-N reduced remarkably and the proportion of the NO2-N exceed NH4-N.The annual variation of the nutrients of the NO3-N concentration:winter > autumn > spring > summer,the concentration of NO2-N:summer > autumn > spring > winter;the concentration of the NH4-N is lower in summer and autumn,higher in spring and winter;but for the PO4-P,the concentration in winter is equal to that in spring and higher than autumn or summer.The annual variation of the water column DO value as follows:winter = spring > autumn = summer,the annual variation of pH change is:spring > winter > summer > autumn.All these data indicated that the moderate nutritional status of the four breeding points anniversary in Sandu'ao.
