季风强度影响中国史上朝代更替

论文作者:Pingzhong Zhang 期刊:《科学》 发布时间:2008-11-7 13:54:23

据11月7日的《科学》(Science)杂志报道说,从中国的万象洞(Wanxiang Cave)中发现的一根石笋所重新构建的一个长达1810年的有关亚洲季风的纪录,为人们就季风强度如何与北半球气温、冰川周期及太阳的波动发生联系提供了独特的一瞥。Pingzhong Zhang及其同事的分析还突显了季风与数个中国朝代的兴亡之间的关系。

几个世纪以来,亚洲的季风为农作物的灌溉提供了十分需要的水源。在季风强烈的时期,如北宋等王朝,它们享有稻米耕作增加以及人口急速发展的美好时光。Zhang及其同事说,后来的干旱季风时期与唐、元及明朝的衰亡在时间上一致。他们注意到,在1960年前后,气温和亚洲季风变化之间的相关性表明,温室气体和悬浮颗粒可能是现在处于支配地位的对季风的影响力。(来源:EurekAlert!中文版)

有这一说,但仅这一说,又把问题简单化,庸俗化了。
