草原啮齿类动物生态作用及生存威胁

The ecological role of and survival threats to grassland rodents

草原啮齿类动物是草原生态系统中不可或缺的重要组成部分,对于维持和优化草原生态系统的功能具有重要作用。但是,草原管理部门往往重点关注草原啮齿类动物所带来的消极负面影响,却忽视或严重低估其发挥的生态作用,造成草原啮齿类动物的生存受到了威胁。因此,本文通过介绍草原啮齿类动物所起的生态作用-草原生态系统工程师和关键种,并对其现阶段所面临的威胁-栖息地丧失、种群灭杀、疾病和外来物种入侵以及气候变化带来的影响做总结,以期为草原啮齿类动物管理及保护提供参考。

Grassland rodents are an indispensable part of grassland ecosystems and play an important role in maintaining and optimizing the function of grassland ecosystems.However,these rodents are threatened by the grassland management departments that often focus on the negative effects of grassland rodents and ignore or seriously underestimate the ecological role that they play.Therefore,this paper describes the key grassland rodent species and their ecological role in grassland ecosystem engineering,and summarizes the threats that they are currently facing(including the effect of habitat loss,population killing,disease and alien species invasion and climate change),thus providing a reference for grassland rodent management and protection.
