武汉月湖水体营养物质的分布与硅藻的生态指示

Distribution of nutrients and ecological indexes of Diatom about Moon Lake in Wuhan

研究了模拟水生生态系统中沉水植物对水体营养物质消减的影响。

Effect of submerged plants on nutrient removal was studied in small model aquatic eco-systems consisting of water , sediment and submerged plants .

得出结论：在微生物处理下，水体的营养物质浓度不断降低，水体的浊度下降，透明度升高，使得实验水体的水质得到了明显的改善。

It is concluded that the density of nutriment of the water body is reduced constantly , turbid degree of the water body dropped and the transparency risen , making the water quality of experiment water body get obvious improvement .

应用藻类大规模培养改善水质，去除污水以及富营养化水体中的营养物质和有害金属至今已得到深入研究。

Heretofore , algal biotechnology has been extensively studied and applied in improving water quality and removing nutrients and metals from eutrophic or contaminated waters .

富营养化水体中胶体有机营养物质研究由血液作为全部营养物的培养基。

Study on the Colloidal Nutritious Material in Eutrophic Seawater ; a culture medium containing whole blood as the nutrient .

水体富营养化是指天然水体中由于过量营养物质的排入，引起各种水生生物、植物异常繁殖和生长的现象，富营养化的水体往往伴随着藻类的大量繁殖。

Eutrophication refers to the phenomenons that there are a variety of aquatic animals and plants reproducing and growing abnormally due to the discharge of excessive nutrients , and often accompanied by algae blooms .
