摘要
玛曲县草原的主体类型是高寒草甸,这里是黄河重水源涵养区和补给区,是国家和甘肃省主体功能区规划确定的生态安全屏障重点区域,高寒草甸具有十分重要的特殊功能和生态地位。长期以来,由于地处高寒牧业地区,受自然和人为因素的影响,全县天然草场不同程度出现退化现象,草原生态功能得到削弱。轻度退化,作为草原退化的初始阶段,具有基础好、易恢复、能巩固的的显著特点,如能得到有效保护,对防止退化演替升级和维护现有生态功能具有重要的意义。本文针对轻度退化草原,采取不同恢复措施,通过对比研究,探索出经济而又便捷的模式作为实践应用指导。
The main type of grassland in Maqu County is alpine meadow,which is the conservation area and supply area of the Yellow River heavy water source,and is the key area of ecological security barrier determined by the national and Gansu Province main functional area planning.Alpine meadows have very important special functions and ecological status.For a long time,due to its location in the alpine animal husbandry area,due to the influence of natural and human factors,the natural grassland in the county has been degraded to varying degrees,and the ecological function of the grassland has been weakened.As the initial stage of grassland degradation,mild degradation has the remarkable characteristics of good foundation,easy recovery and consolidation.If it can be effectively protected,it is of great significance to prevent degradation,succession and upgrade and maintain existing ecological functions.This paper adopts different restoration measures for mildly degraded grassland,and explores an economical and convenient model as a practical application guide through comparative research.
