摘　　要：土壤酶在生态系统的物质循环和能量转化过程中扮演重要的角色。对土壤酶活性的时空动态分布、酶活性对土壤水气热状况、土壤酸碱性、土壤有机质以及外源营养物质输入的响应研究进展进行了综述。进一步加深理解土壤酶在生态系统中的重要作用,并对湿地生态系统土壤酶活性的研究发展前景进行了展望。Soil enzymes play important roles in soil nutrient element circulation and energy exchange in the ecosystem. In this article, the study on ecological environment factors affecting soil enzyme activity was reviewed. Several aspects such as the space-time distribution of soil enzyme activity, the influence of soil temperature, moisture, pH value, soil fertility and nutrient matter on soil enzyme were included. At the same time, the study on soil enzyme activity in the wetland ecosystem in the future research was forecasted.
