【摘要】 土壤酶能够把高相对分子质量的有机化合物分解成为能够被生物利用的简单化合物,土壤酶的分解作用普遍被认为是生态系统中有机物质分解过程的限制性步骤,控制着湿地生态系统的物质循环.本文对湿地生态系统中土壤酶的时空格局、影响酶活性的环境因子、与全球变化的关系以及在湿地净化功能中的意义等几方面进行了综述,并强调应在人类活动影响下湿地土壤酶的作用方面加强研究.更多还原

【Abstract】 Soil enzyme can decompose high_molecular organic compounds into simple compounds that can be utilized by organism. The catalisis of soil enzyme is common to be thought as limiting step of decomposition of organic compounds, which comtrol the cycling of materials in wetland ecosystem. The paper summarized the recent progress on studies on soil enzymes in wetland ecosystem as below:temporal and spatial pattern, ecological factors affecting soil enzyme activities,relation between global change and soil enzyme, and function of soil enzyme in decontamination of wetland.The function of soil enzymes under human disturbance in wetland ecosystem need be studied emphatically.更多还原
