清代以前,云南境内的金沙江流域河谷地带森林茂密、草原丰美、气候湿润,并未呈现干热河谷灾变景观。入清后,随着移民的增加,开发管理的无序,加之引入的经营模式与当地生态系统不相兼容,经长期积累后,毁损了多样并存的森林生态系统,诱发了干热河谷生态灾变的扩大化,危害了人类的生存和发展。要根治今天云南境内金沙江流域干热河谷灾变,应借鉴历史的经验,充分发掘、利用原生地各民族的传统生态知识和技能,这一地区干热河谷灾变救治才可望收到理想成效。
Before the Qing Dynasty, the Jinsha River Valley in Yunnan Province had dense forests, rich grasslands and humid climates, and did not show the landscape of dry-hot valleys. After entering the Qing Dynasty, with the increase of immigrants, the disorder of development and management and the incompatibility of the introduced management mode with the local ecosystem, the long-term accumulation has destroyed diverse forest ecosystems and induced the ecological catastrophe of dry-hot valley The magnification has jeopardized the survival and development of mankind. In order to cure the catastrophe of the dry-hot valley in the Jinsha River valley in Yunnan today, we should draw lessons from the experience of history and fully exploit and utilize the traditional ecological knowledge and skills of the native peoples. Only in this way can we expect the dry-hot valley catastrophe treatment to achieve the desired result.
