摘要
为了更好的了解哈素海水体中营养盐的分布情况,进一步评估其富营养化程度,2019年4月采集哈素海水体10个水体样品,通过实验方法确定哈素海水体营养盐的空间分布情况,并采用营养状态指数法对水体富营养化程度进行评价。结果表明哈素海水体中总氮、总磷均有4点超标,超标率40%。通过计算营养状态指数发现有两个采样点属于中富营养程度,其余点位均呈轻富营养程度,且氮、磷均为水体的营养盐限制性因子。为防止哈素海水体进一步富营养化,应控制氮、磷的引入。
To know the distribution of the nutrient in water better and evaluate the eutrophication degree,10 sampling sites were set in April 2019 to determine the nutrients distribution.Trophic state index was used to evaluate the degree of eutrophication of Lake Hasuhai.The TN concentration results showed that 4 points of all exceeded the level of standard,and the rate was 40%.The TP concentration results showed that four points of all exceeded the standard.Water eutrophication degrees of Lake Hasuhai showed that two sampling points were at medium eutrophication degree,and the other points were light eutrophication degree,and nitrogen and phosphorus concentrations were the limiting factor of nutrients in Lake Hasuhai.In order to prevent further eutrophication of the lake,nitrogen and phosphorus should be controlled.
