| Abstract: | The closely reciprocal feedback between cryosphere and biosphere has constantly been intensified by global change, which strongly affects global management for environment and sustainable development of human-being. From the perspective of basic pattern and function of cryosphere ecosystems, and their response process and adaptive strategy to changing environment, we fully specified distribution patterns of cryosphere ecosystems and how it functioned for earth ecosystems and contributed to human well-being, briefly stated how it is most sensitive, thereby as an indicator to climate change, also pointed out cryosphere ecosystems as barrier function for maintaining biodiversity and increasing productivity, and finally put forward an effective way to facilitate ecosystems health in cryosphere. Totally, the common contents and corresponding study processes in cryosphere ecology were better to be introduced, even essential prospective of cryosphere ecology was included in this paper. |
