| 摘 要： | 对广东韶关铅锌矿冶区植被恢复地的土壤酶活性进行了测定.结果表明,自然植被恢复地(ZR)的脲酶、蛋白酶、过氧化氢酶、蔗糖酶活性高于人工植被恢复地(RG)和无植被覆盖地(GB),其中脲酶、蛋白酶在ZR的活性极显著高于其在RG和GB的活性(P<0.01).脲酶、蛋白酶、过氧化氢酶活性与植被盖度、生物量等特征呈较高相关性.建议用土壤脲酶、蛋白酶活性作为Pb/Zn矿冶区植被自然恢复的指示指标,过氧化氢酶作为参考指标.图1表1参18

| Abstract: | The activities of selected soil enzymes, including urease, proteinase, catalase and sucrase, were determined in vegetation naturally restored area (ZR), artificially restored area (RG) and barren area (GB) of lead-zinc mining and smelting circumjacet districts. The results showed that the activities of the four soil enzymes in ZR were higher than those in RC and GB; and the activities of urease and proteinase in ZR were most significiantly higher than those in the others (P<0.01). The activities of urease, proteinase and catalase had a higher positive correlation with vegetation coverage and biomass. It is suggested that the activities of urease and proteinase could be used as primary indicators for the restoration of lead-zinc mining and smelting circumjacent districts, while catalase could be used as secondary indicator.
