1世界山地:21世纪脆弱的“水塔”显示文摘山地作为'天然水塔'在周围低地的生存和发展中扮演者重要的角色。对于世界上的很多干旱和半干旱地区更是如此,因为那里的山区来水可以占到径流总量的50%~90%。然而在这些水资源日益紧缺(特别是农业用水紧缺)的地区,利用我们现有的山区水文方面的知识来进行可持续的水资源管理与脆弱性评价仍面临着很大的困难。IPCC报告中指出,如果大气中的CO_2增加1倍,那么全球增温幅度最大的地区将会包括从北极和亚北极的低海拔地区到热带亚热带的高山区的广大区域。计划中的GCOS气候站点并未达到这样的高度,尽管这里温度变化较大,拥有许多生态系统敏感而脆弱的高峰。全球范围内,山区居民超过了7亿,其中有6.25亿是在发展中国家。而这6.25亿人中约有一半人,当食物供给没有保障时是非常脆弱的,其后果可能会是向外移民或者对山地生态系统进行过度开发。而这些生态系统的过度开发最终会对自然环境,特别是水资源,产生负面的效应。迫切需要开展一些新的研究项目,建立高山观测站点,以深入了解各种正在发生的自然过程和人文过程及其对相邻低地所产生的影响。Bruno Messerli Daniel Viviroli Rolf Weingartner 韩海东 2004AMBIO-人类环境杂志2004,0,S1:2
