biological assessment meaning in English
生物鉴定,生物评价
生物学判断；生物学评价
Examples
- Only the water at jiekou had been eutrophic . the result of biological assessment was that the average density of phytoplankton at all the sampling spots was more than 1 , 000 , 000 per litre , indicating that the lake was eutrophic going by the population density . but this density of phytoplankton was higher than that in similar lakes at the same pollution level
生物评价结果认为，千岛湖浮游藻类平均密度较同类营养水平的淡水水体高，其所有取样点浮游藻类平均密度都10 ~ 6个? l ，国内外一般认为当浮游植物平均密度10 ~ 6个? l时，其已经达到富营养化水平，因此单从浮游植物密度来看，可以认为千岛湖已达到水体富营养化。 - Qiandaohu lake was very famous for its clean water quality . but in recent years the water body has become seriously eutrophic especially during summer months in some areas of the lake and came to the attention of national , provincial and city environment protection agency . the main objective of this study involved the following : sampling and monitoring water from the lake ; water quality assessment and biological assessment ; ascertain the limiting factors for phytoplankton growth ; fuzzy cluster analyse of water pollution of all sampling points ; predicting total phosphorus concentration in the lake by using static models ; setting up regression models and their application ; setting up an eco - dynamic model and its simulation
本研究根据1998 - 2000年连续监测数据，对千岛湖进行了水质评价和生物评价；分析了千岛湖水体富营养化的限制性因子；同时根据千岛湖各个取样点的污染状况，对千岛湖进行水环境质量区划；利用前人的经验统计模型预测了千岛湖现有的磷浓度水平及治理所需要削减的污染物负荷量；并且组建了多个回归统计模型，运用这些模型预测千岛湖水体中的总磷浓度；最后根据多年水质、底质、生物等方面的监测数据以及千岛湖流域的气象和社会经济状况的资料组建机理性的千岛湖富营养化模拟模型。
