汉唐时期长江中下游地区环境的优化——从“含沙射影”词义的演变谈起

Optimization of the Eco-environment in the Middle-Lower Yangtze Area during the Han and Tang Dynasties——Starting from the Change of the Meaning of “Hansha She Ying”

从汉至唐,"含沙射影"的含义,由含沙暗中攻击人的方式,演变为阴谋诬陷别人的行为。其词义的变化,反映了含沙社会影响力的减弱以及长江中下游地区生态环境的变迁。随着长江中下游地区经济的发展及其农业景观的建立,含沙的生存环境发生显著变化,其分布范围逐步缩小,这一地区的生态环境得到优化,更加适宜人们的居住。

From the Han Dynasty to the Tang Dynasty, the original meaning of ＂Hansha she ying＂ transtorms from the way that Hansha injures people stealthily into the behavior that one complots to frame and slander others. The variation of its meaning reflects the decrease of social influence power of Hansha and the changes of ecologi- cal environmental in the Middle-Lower Yangtze Area. The development of southern economy and the establish- ment of agricultural landscape have made the living environment of Hansha change fundamentally and its distribu- tion range has reduced gradually. The ecological environmental of the Middle-Lower Yangtze Area has been opti- mized, which makes it more livable.
