| 摘 要： | 在藻型富营养化的湖泊水体中应用有效微生物群菌剂的结果表明，有效微生物群对水体的透明度，叶绿素ａ含量的改善有明显的效果，可有效抑制藻类的生长，防止水华的发生，改善景观，在投入有效微生物群后，透明度迅速提高，２个月后，透明度提高了４３３％；水体表面的叶绿素ａ含量在１个月后下降了９６．５％并维持在１３７．９ｍｇ／ｍ＾３以下；水深０．５ｍ处的叶绿素ａ含量在投放菌剂期间及之后１个月保持在１００ｍｇ／ｍ＾３以

| Abstract: | Effects of effective microorganisms(simplified as EM) on control of algae bloom in eutrophic water were studied in a small lake in South China Botanic Garden of Chinese Science Academy where algae bloom frequently occurred The results showed that content of Chl a both on the water surface and 0 5 m below the water surface,total N and P, and COD Mn decreased after the spraying of EM, while the content of DO and water transparency increased accordingly The very remarkable decrement of Chl a on water surface indicated that the algae bloom had been completely controlled, and it contributed directly to the increase of the water transparency The decrements of the content of total N and P, and organic matter seemed to be the main factors which caused the decreasing of algae However, it is difficult to explain why the BOD 5 increased The period that EM keeps active in controlling algae is estimated to be about one and half a month |
