摘要/Abstract

摘要： 通过野外调查和实验分析,研究了芜湖火力发电厂灰渣场土壤蔗糖酶、过氧化氢酶和脲酶活性与土壤污染物及植被的关系.结果表明,灰渣场植被多以单种植物组成的斑块零散分布,以草本植物为主,且多为1～2年生.同时,灰渣场3种土壤酶活性和渣场的自然环境条件具有较强的相关性,其中3种酶活性对环境胁迫的敏感性依次为脲酶>蔗糖酶>过氧化氢酶,3种酶活性与环境中因子的相关性整体表现为蔗糖酶>脲酶>过氧化氢酶.由于对环境胁迫最为敏感,而且其活性与植被状况和土壤化学性质具有显著或极显著相关性,建议用脲酶活性作为废弃地复垦的一个指示指标.

Abstract: From field investigation and laboratory analysis, the relationships among soil enzyme activities,vegetation state and soil chemical properties of coal cinder yard in thermal power station were studied. The results showed that vegetation on coal cinder yard was distributed in scattered patch mainly with single species of plant, and herbs were the dominant species.At the same time, the activity of three soil enzymes had a stronger relativity to environment conditions, such as vegetation state and soil chemical properties.The sensitivity of three soil enzymes to environmental stress was in order of urease >sucrase>catalase. The relativity of three soil enzymes to environmental factor was in order of sucrase> urease > catalase. Because of urease being the most susceptible enzyme to environmental conditions, and it was marked or utmost marked interrelated with vegetation state and soil chemical properties, urease activity could be used as an indicator for the reclamation of wasteland.
