| 摘 要： | 为确定污水、污泥的农田施用标准，使用正交试验表L9（34）研究了4种重金属铜、镍、铅和锌在低、中、高3种浓度下对土壤藻类的数量和种类的影响。混合重金属使土壤藻类的种群结构发生改变，使蓝藻数量减少，硅藻数量或减少或增加，视条件而定，裸藻成为优势种。在土壤－藻类体系中重金属临界值铜为50mg/kg，镍为50mg/kg，铅为150mg/kg，锌为300mg/kg。

| Abstract: | Orthogonal test table L9(34)is used for studying the effect of heavy metals-copper, nickel, lead and zinc at three different levels on the composition of algae in paddy soil.The mixed heavy metals affect the structure of soil algal communitiesi e.g.the number of blue algae (cyanobacteria) decreases,and the number of diatom increases or decreases. The genus Eugleo becomes the dominant species.The critical levels of the heavy metalsare discussed. |
