摘要
1996年11月—1998年11月，对鄱阳湖等长江中下游若干浅水湖泊进行了水化学分析，并进行了主要水质指标(包括透明度、pH值、总氮、总磷、氨氮和硝酸盐等)的季节变动规律，并对这些指标进行了方差分析。结果表明：不同利用方式的水体间除硬度、碱度和T-N在几个湖区间的差异较小外，其它各项指标的差异均较显著；季节间除硬度、碱度、Ca、Mg和T-P外，其余各项指标在季节间的差异均较显著，说明其季节变动均不稳定。
Aquatic-chemistry of the lakes including Poyang Lake, Niushanhu Lake, Liangzihu Lake, East Tangsunhu Lake, Longganhu Lake and Huanghu Lake were analyzed from Nov., 1996 to Nov., 1998. On the bases of water quality mornitoring, the seasonal dynamics of main water quality indices (such as transparency, pH, total-nitrogen, total-phosphorus, ammonia nitrogen and nitrate-nitrogen, etc.) and variance analysis of those indices were determined out. The results showed that the difference of the some indices among several lakes with different exploitation models was quite significant except hardness, alkalinity and T-P. The differences of some indices among seasons were also quite significant except hardness, alkalinity, Ca, Mg and T-P. It is implied that the seasonal dynamics at these lakes were quite unstable.
