唐代沙尘灾害研究

Research on the sand and dust calamities of the Tang Dynasty

通过大量文献资料和现代科技研究成果,试图说明唐代历史上发生的各种类型的沙尘灾害不仅史不绝书,且有频繁发生之势,并给人们的社会生活带来了严重危害。认为导致沙尘灾害发生的原因,除当时中国西北、北部和东北地区分布着辽阔的天然沙漠、沙滩、沙尘等原始的沙化源地及其受到反厄尔尼诺事件的影响以外,唐代统治者的大兴土木,城乡居民把炭薪作为日常生活资料,手工业多种部门以木材作为原料和燃料,以及逃户和移民对原始植被的大量焚烧垦种,导致地表植被的日益萎缩,原始生态环境的日益恶化,新的沙化源地的不断扩大,也是加剧沙尘灾害频繁发生的主要因素。

Almost all kinds of sand and dust calamities have happened in the Tang Dynasty and the reasons of which were the extensive sources of desertification,such as natural deserts,sand beaches,ect. Another reason is the inflence of EINino. Besides, the rulers of the Tang Dynasty as well as the people in rural and urban areas caused sand and dust calamities to happen more frequently.
