| 摘 要： | 全球气候变化对自然生态系统和人类社会系统的各个方面产生了很重要的直接影响,其中冰冻圈由于其脆弱性与灵敏性而首当其冲.同样,气候变化通过影响冰冻罔而对自然生态系统和人类社会系统产生很重要的间接影响.通过论述冰冻圈变化的影响,选取较为典型的领域,在时空尺度、作用机制以及影响过程等方面,对气候变化背景下我国冰冻圈变化的具体影响进行了识别.结果表明,气候变化的正面或者负面影响通过冰冻圈变化的作用之后可以加强或者削弱,从而为制定冰冻圈变化的适应对策提供科学依据.

| Abstract: | Climate Change has some great impacts directly on natural ecosystem and human society,of which the cryosphere is most easily affected because of its vulnerable and sensitivity.Similarly,cryosphere change has a lot of impacts on natural ecosystem and human society,which may look as an indirect influence of climate change.These two kinds of impacts in some typical fields are distinguished in some space-time scales,effective mechanisms and processes.Climate change has positive and negative impacts on some syst... |
