土壤酶及其生态指示作用研究进展

Research Progress on Soil Enzymes and Their Functioning as Ecosystem Indicators

土壤酶催化土壤生物地球化学反应,推动土壤生态系统中的物质循环和能量流动。从土壤酶的来源、存在状态及功能、土壤酶活性的分布特征及时空动态变化进行了概述,强调了土壤酶活性对土地利用方式、耕作管理、施肥、农药和地膜的使用及重金属污染等的生态指示作用,为更好地利用土壤酶来及时了解土壤生态系统功能的运行状况及采取适当管理措施提供支持。

Soil enzymes catalyze biogeochemical reactions in soil and drive material circulation and energy flow in the ecosystem.This paper summarized soil enzyme sources,status,functions,distribution characteristics and spatiotemporal dynamics,emphasizing that soil enzyme activities indicate changes in land use type,tillage and management,fertilization,pesticide application,plastic film use and heavy metal pollution in ecosystem.This paper was expected to provide support for better learning soil ecosystem function changes so that proper management measures can be taken as soon as possible.
