气候对人们的心理、生理各方面都有微妙的影响。秋季是天气变化较为活跃的季节,而且秋天的气候有它的双重性,既有金风送爽、凉爽宜人的有利方面,又有乍热乍冷、气候干燥的不利方面。特别是深秋,昼短夜长,秋风萧瑟、万木凋零、景物肃杀的自然环境和秋雨绵绵、阴霾冷湿的天气,会给人们尤其是中老年人,带来凄凉、郁闷和迟暮的感触,使人悲哀、忧虑和伤感。这就是千百年来文人骚客吟唱的“悲秋”情绪。 Climate has a subtle influence on people’s psychology and physiology. Autumn is a season in which the weather changes more actively. Moreover, the climate in autumn has its duality. It has both the golden wind and the cool, pleasant and favorable aspects, as well as the unfavorable aspects of cold weather and dry climate. Especially in late autumn, long days and short nights, bleak autumn winds, wow wood dying, the scene of the natural environment and the autumn rain, hazy haze of the weather, will give people, especially the elderly, bring bleak, depressed and late feeling, People sad, worried and sad. This is the “sad autumn” mood sung by the literati poets for thousands of years.
