摘要
文章在查阅相关文献的基础上,开展实地考察、咨询专家学者和有关管理部门,对西藏高原草地研究进行梳理归纳形成了4个时段;同时评析了不同调查结果的西藏草地面积,认为第二次西藏草原普查的8820.15×104 hm2比较符合现状;对西藏高原草地生态系统目前面临的最大问题—草地退化进行了探究,截至2012年,西藏天然草地退化面积达2355.54×104 hm2,占全区可利用草地面积的30.53%,其中草地退化以轻度退化为主;同时为更好地保护高寒特殊地区草地生态系统、确保其可持续发展,从现代生态修复学原理,提出几点生态修复技术措施的建议,为有关决策和研究提供参考。
According to the literatures,the field survey,consulting the experts and relevant administrative departments,the research history of the Tibetan Plateau grassland could be divided into four stages.The grassland area reported by various researchers was also analyzed.8820.15×104 hm2 of the grassland area reported by the second grassland census was believed in constant with the current status.In addition,the grassland degradation was also studied.The area of the natural grassland degradation in Tibet was 2355.54×104 hm2 accounting for 30.53%of the total available grassland area by 2012.It mainly belonged to a mildly degradation.In order to better protect the grassland ecosystem in alpine areas and ensure its sustainable development,this paper proposed several ecological restoration technical measures based on the principles of the modern ecological restoration and aimed to provide references for the relevant decision and research.
