| Huoshan county,which is located at the north side of Dabie Mountains and the upper reaches of Pi River which is the first grade tributary flowing of Huai River,has a graceful environment and contains a great number of valuable natural resources.In this condition,it has a reputation of “great places filled with medicine and precious tea,lovely country insists of bamboo and white mulberry”.According to the Geographical Analysis of Chinese Medicinal Materials in Huoshan County in Qing Dynasty,there are 42 kinds of Chinese medicines in Huoshan county in Qing dynasty,which had a particular advantage over other countries such as Luan state,Yingshan county,Qianshan county,Shucheng county,Taihu county,Shangcheng county in geographical environment.A large number of Mountains and rivers distributed in the west-south of Huoshan county,meets the needs of illumination,quantity of heat,hydrology and soil in the growing of Chinese medicine in Huoshan county.Contributed to this superior situation,the medicine of Huoshan usually distributed in the west-south of this county.Dendrobium huoshanense and Poria cocos,which are both the traditional and genuine medicine of Huoshan county in Qing dynasty,are facing a rough fate of being in imminent danger.The number of the local wild Dendrobium huoshanense had suffered four times of abrupt decreasing during the period of last days of south-song dynasty,Wanli period of Ming dynasty,Qianlong and Guangxu period of Qing.The reason of Dendrobium huoshanense’s disappearing in the time of Qing dynasty is that the wilding Dendrobium have a long growth period,once being exploited,the growing of a new generation may continue in hundred years.Besides,the main reason of this disappearing is the pursuit of profits.In the stimulate of interests,local people overexploitacted the medicine without proper protection.The way of planting large amount of genuine Poria cocos medicine comes from Yunnan province,discovered by predecessors and was planted massively.In the stimulate of interests,the phenomenon of abandoning farming and reclaiming mountains to plant Poria cocos had became even more violent in Huoshan.The main way of Poria cocos cultivation is “guide by woods”,so the pine tree is indispensable.However,with the upsurge of Poria cocos planting,the local residents who chop down the trees and without proper skills of planting Poria cocos always suffered a high loss,leaving the mountains ruined and environmental disruption.This kind of outcome is inescapable.The abundant of natural resources does not equal to endless using of them.The Huoshan residents’ s behavior of overexploitaction without any consideration of foresight should be prohibit.The paper analysis the change of Dendrobium and Poria cocos in Qing dynasty.With some landscaping in small places,The aim of this is to be a light sleeper to take history as a mirror and in the presupposition of keep a balanced relationship between human being and the environment to utilize the natural resources in a proper and scientific way,and do not follow the same old disastrous road.This concept should be advocated especially in the background of “hot-topic of medicine” nowadays. |
