张衡的《南都赋》中记载有汉代南阳地区的自然生态情况 ,如丰饶的山林、金丝猴的生存状况、甘蔗和甘橘的栽植等 ,但后来都不见于记载了。其原因除了人类活动的影响之外 ,气候变迁又也是重要因素。通过对《南郁赋》中自然生态史料的研究 ,有助于推动历史时期自然生态变化研究。 Zhang Heng’s “Nandu Fu” records the Nanyang area in the Han Dynasty, the natural ecological conditions, such as abundance of forest, golden monkey survival conditions, planting sugar cane and tangerine, but later not seen in the record. The reason is that in addition to the impact of human activities, climate change is also an important factor. Through the study of the natural ecological materials in “Nan Yu Fu”, it helps to promote the study of the natural ecological changes in the historical period.
