| 摘 要： | 运用正交试验设计方案，考察了酸雨、重金属铜和农药莠去津复合污染情况下各因素的主效应及两两交互作用对土壤脲酶、转化酶和酸性磷酸酶活性的影响。结果表明，H^+、Cu^2+对酶活性影响显著且其对3种酶的抑制效应为H^+>Cu^2+；Al^3+仅对脲酶表现出一定的激活效应；而除磷酸酶外，莠去津对脲酶、转化酶活性无明显影响。交互作用试验表明：莠去津×Cu的协同作用主要表现为对磷酸酶活性的影响；而H×Cu对脲酶、转化酶均表现为颉抗作用；在本文所考察的浓度范围内，未见莠去津与氢有显著的交互作用存在3种酶中，以磷酸酶对外来污染物最为敏感。

| Abstract: | The effects of acid rain, Cu2+ and atrazine on the activities of soil urease, invertase and acid phosphatase were studied by means of orthogonal test. The results showed that the inhibition rate was H+ > Cu2+, and atrazine had no significant influence on urease and intertase. Interaction analysis revealed that Cu x atrazine exhibited synergism on soil acid phosphatase activity, Cu x H had antagonism on soil invertase and urease, but atrazine x H had no interaction within the investigated concentration range. Among the three enzymes, soil acid phosphatase was the most sensitive one to the contaminations. |
