干扰对草地植物物种多样性的影响研究

Effects of disturbance on species diversity of grassland plants

分析干扰与物种多样性的关系,不同干扰方式、不同干扰强度、不同干扰历史对草地植物群落物种多样性的影响不同,有时也存在自然与人为干扰的复合作用。对其研究,以期为水土保持、植被恢复、退耕还林还草等工程实践和相关研究提供参考。

The relationship between disturbance and species diversity is analyzed.Different disturbance modes,intensity and history have different impacts on species diversity of grassland plant communities.Sometimes,natural and man-made disturbances also have complex effects.It makes research on this subject,and it provides reference for engineering practice and related research on soil and water conservation,vegetation restoration,conversion of farmland to forest and grassland,etc.
