| 摘 要： | 通过不同年限的野外调查和土壤理化特性的分析,揭示了随着时间的演替变化、磷矿废弃地植被的群落结构和生物多样性、土壤肥力、土壤酶活性的变化规律。结果显示,随磷矿废弃地时间的演替,磷矿废弃地植被群落结构相对丰富,均匀度增大,生物多样性提高;酸性磷酸酶、脲酶随着磷矿废弃地时间的演替,上下层含量相对于对照都有所增加;而过氧化氢酶却随着磷矿废弃地时间的演替减小。

| Abstract: | The field investigation and the soil chemical properties in the different year were analyzed.The research revealed the rule of plant community,biodiversity soil fertility and soil enzyme with the time succession.The results showed that with the time changed,community and biodiversity increased,the evenness was improved.Acid phosphatase and urease value also increased compared with control group.However,the catalase was reduced with the development of time. |
