摘要
甘、青、宁三省区位于黄河上游,深处西北内陆,生态环境较为脆弱,因此对气候之冷暖干湿变化极为敏感。根据历史文献中的相关记载,并辅以自然科学领域的相关研究结果,分析认为10—13世纪黄河上游地区的气候经历了由寒冷期至温暖期再到寒冷期的大周期循环变化过程,同时也完成了由相对湿润气候向持久干旱气候过渡的渐进式转变。气候变化并不以人的意志为转移,因而黄河上游地区的气候在百年尺度的大周期循环过程中,依然会存在一些小幅度的气候波动和季节特征。这能为我们应对全球气候变化提供些许借鉴。
The provinces of Gansu,Qinghai,and Ningxia are situated in the upper reaches of the Yellow River within the deep inland region of northwest China.Due to their delicate ecological environment,they exhibit a high sensitivity towards climate variations encompassing cold,warm,dry,and wet conditions.By analyzing relevant historical literature records and complementing them with research findings from natural sciences fieldwork,it is determined that the climate in the upper reaches of the Yellow River underwent significant cyclic changes from the 10th to 13th century.These changes involved transitioning from a cold period to a warm period and then returning back to a cold period.Simultaneously,there was also an evident shift from relatively humid climatic conditions towards persistently arid ones.It should be noted that climate change is not influenced by human willpower alone;hence even within large-scale century cycles,small fluctuations and seasonal characteristics continue to manifest in the climate patterns observed in this region.
