摘  要:
为分析封育对亚高山草甸植物的影响,2012年至2014年每年9月下旬,测定青藏高原东南边缘云南省西北部香格里拉县封育草地植物学组成。结果表明,与退化区相比较,封育1~3a期间,草地植物数量增加了1~11种。4个试验点中的两个点(拉杂坝和肯公)植物种类分别从29种、35种持续上升到37种、46种。

摘  要:
From April 2012 to September 2014,the responses of degraded sub-alpine meadow to continuous enclosing were tested in shangri-la county which located at the southeast margine of Tibeten in the northwest of Yunnan province. The degraded sub-alpine meadows were enclosed in April 2012,and botanical composition in both degraded pasture and enclosed pasture were monitored in each end of September from 2012 to 2014. The resulrs showed that the enclosed pastures have 1 or 11 more plant species during three years enclosing period compared with the degraded pasture,plant species continued to rise from 29 and 35 in degraded pasture to 37 and 46in enclosed plots at two of four test areas,respectively.
