摘要
作为土壤生态系统中的重要组成部分及生物元素循环的积极参与者,土壤酶在陆地生态系统地下生态过程中扮演着十分重要的角色。升高温度和(或)大气CO2浓度可能直接或者间接影响其活性。但目前对温度和(或)大气CO2浓度升高对土壤酶的影响机理、过程及土壤酶对其的响应机制研究相对薄弱。本文初步总结了国内外关于温度和(或)大气CO2浓度升高对土壤酶活性影响研究的现状,并指出了目前研究中存在的不足。
Being an important component of the soil ecosystem and an active participator of material cycling, soil enzymes play a key role in underground ecological process in the terrestrial ecosystem. Elevation of temperature and/or atmospheric CO2 concentration may impact the activity of soil enzymes directly or indirectly. However, studies on influences of enhanced temperature and/or CO2 concentrations on feedback mechanism and process of soil enzymes are inadequate. Advancements and progresses of the studies on soil enzymes in relation to temperature and CO2 are reviewed, and recommendations presented for further systematic researches on relations between soil enzymes and factors of global changes.
