| 摘 要： | 对黄河三角洲冲积平原湿地酶活性与土壤养分相关性做了研究。结果表明,随着离海距离的增加,土壤有机质及各养分表现出有规律的变化,土壤脲酶、过氧化氢酶活性沿湿地演替的方向活性升高,过氧化物酶活性降低。土壤有机质和各养分与酶活性相关性达极显著和显著水平,不同土壤酶活性之间也有显著的相关性。三种酶可以作为评价黄河三角洲冲积平原湿地土壤肥力的指标。

| Abstract: | Correlative research was made on the activity of enzyme and soil nutrient of different wetlands in Yellow River Delta. The results show that soil organic content and great nutrient content change regularity as it far away from the sea. The enzyme activities of urease and catalase in wetland soils were almost in the same order, but the activity of soil peroxidase was on the contrary. Enzyme activities of soil were significantly related to soil nutrients. There were also correlations among different enzyme activities. So enzyme activities could be used as an index for soil fertility evaluation of wetlands covered with different vegetation in Yellow River Delta. |
