摘 要:休牧是治理退化草地,实现近自然恢复的有效且成本投入较低的途径,对我国退化草地的恢复工作十分重要。本文采用文献综述法,对春季休牧、夏季休牧和秋季休牧对退化草地生态恢复的影响、休牧时间和年限的选择以及休牧促进退化草地生态恢复的机理进行了综述,明确春季休牧是休牧措施中的首选,休牧时间多推荐为60天,休牧年限在10年内越长越好。本文可为休牧措施的实施及进一步的调控机理研究提供理论依据。Grazing exclusion is an effective and low cost way to restore degraded grassland.It is of importance for the restoration of degraded grassland in China.In this paper,the influences of grazing exclusion conducted on spring,summer or autumn on ecological restoration of degraded grassland,the optimal time and years,and the mechanism of promoting function of grazing exclusion on ecological restoration of degraded grassland were analyzed through literature review.Among the three different seasons,spring was the best choice of grazing exclusion measures.The best grazing exclusion duration was recommended to be 60 days,and the longer,the better within 10 years.This paper can provide a theoretical basis for the further implementation of the measures of grazing exclusion and further research on the promotion mechanism.
