北宋时期气候变化及其对应社会影响

The climate change and its social impact during the North Song dynasty

气候变化的社会影响是当前全球变化影响研究的重要领域之一。从历史角度上研究气候变化及其社会影响可以为当前人类应对以全球变暖为突出标志的气候变化挑战提供宝贵的借鉴。对北宋时期世界各地的气候变化和我国气候变化进行了总结归纳,指出我国独特的自然环境,在北宋时期,前期温暖、后期变冷,处于唐末冷期以及明清小冰期的气候变化敏感的转折时期,气候波动明显,且降水变率大。在北宋时期气候变化影响下,我国洪水灾害发生频率高,对我国的农业生产、社会和经济发展等均造成了极大影响。其研究结果对了解过去气候变化及其影响有重要意义。

The social impact of global climate change is currently one of the important fields of global change research. Studying the historical climate change and its social impact from historical perspective could provide the valuable references for current human response to the global warming. Based on the previous studies, the climate changes in the world and in China during the North Song dynasty were summed up. The study results pointed out that the climate during the North Song dynasty changed from warm in the early stage to cold and dry in the late stage because of the unique natural environment in China, which just lied between the turning period of the late Tang dynasty and the little ice age of Ming and Qing dynasties. The obvious climate fluctuation and the great change rate of precipitation caused the higher frequency of flood disaster during the North Song dynasty, which has caused the great influence on agriculture production, social and economic development. The study results have very important implications to understanding the past climate change and its impact.
