中文摘要
为了深入了解和合理评价气候变化背景下湿地土壤碳、氮等物质循环过程的动态变化。本研究通过对土壤酶在湿地生态系统中的作用及其时空分布特征归纳总结,探讨温度升高、降水变化、温室气体排放增加以及湿地氮营养环境变化等对土壤酶活性的影响。通过总结,认为土壤酶在湿地生态系统中发挥着重要而复杂的作用,气候变化显著影响了其活性,进一步影响湿地土壤碳、氮等循环过程。
英文摘要
In order to understand and evaluate the dynamic changes of soil carbon and nitrogen cycling in wetland under the background of climate change. We reviewed the role of soil enzymes in wetland ecosystem and their spatial and temporal distribution characteristics, and discussed the effects of temperature rise, precipitation change, greenhouse gas emissions increase, and nitrogen nutrient environment change on soil enzyme activities. Based on this, it is concluded that soil enzymes play an important and complex role in wetland ecosystem; climate change significantly affects soil enzyme activities, and further affects the cycling process of carbon and nitrogen in wetland soil.
