摘要
在野外调查的基础上分析了青海省西藏嵩草Kobresia tibetica沼泽化草甸的分布、群落结构及其退化特征。气候的干暖化和人类不合理的生产经营活动是西藏嵩草沼泽化草甸退化的主要原因。并以退化成因为依据,结合当地实际提出了实施生态保护工程、改变草地利用目的与方式,围栏封育退化草地、冲沟治理和加强科学研究等措施,以达到保护和恢复西藏嵩草沼泽化草甸的目的。
According to field investigation, the distribution, structure of community and degradation characteristics of Kobresia tibetica grassland in Qinghai were analyzed; the degradation of K. tibetica swamping grassland was caused by both climate warming and human＇s unreasonable production and operation activities. Basis on the causes of degradation and local actual situations, some measures were suggested that ecological protection engineering should be implemented, purpose and style of grassland utilization should be changed, enclosure should be carried out, rushing gully should be controlled and research should be strengthened in order to protect and recover K. tibetica swamping grassland.
