| 摘 要： | 利用青藏高原河南县典型高寒草甸生态系统群落结构、地上生物量、发育期及其气候、冻土环境观测资料,系统研究了高寒草甸植被生长发育特征及其对气候变化和冻土退化的响应机理.研究表明：20世纪80年代后期以来,随年代进程高寒草甸植被出现了牧草返青初期无明显变化,而黄枯初期显著延迟,致使生长期延长,覆盖度总体下降,但自2004后开...

| Abstract: | Based on the data of permafrost environment,climate,growth period and ground biomass,as well as colony structure,of typical plateau meadow ecological system in Henan Mongol Autonomous County,Qinghai Province,the evolution characteristics of plateau meadow vegetation and its response to climate change,together with permafrost degeneration,is studied systematically.It is found that the initial reviving period has not significant change but the initial scorch period has postponed markedly,resulting in the grow... |
