Research On The Historical Changes Of Qinghai Region Forestry

Human from simple to use fire, the invention and the use of fire, the agriculture is arisenwith development, to the rise of industry, improve productivity, enhance the ability ofutilizing natural resources, population increase, corresponding to forest destruction,especially contemporary, local economic development, along with the only damage to theenvironment, and the pollution of the environment.Forest as the renewable natural resourcesand the main body of the terrestrial ecosystem, environmental protection has a very big role,and Qinghai is the Yangtze River, the Yellow River River, the birthplace of Lancang, knownas the "river source","the towers", therefore, the protection of the area of the forest industry,to protect environment, it is particularly important.Qinghai is located in the northwest region of China, Qinghai natural condition isastringent, bitter cold climate, drought and little rain, forestry development is facing greatdifficulties, but Qinghai has a vast territory, the territory of complex and diverse topography,terrain height disparity, thus forming a "eight different gas, thousands of miles of specialweather" local climate and microclimate.It is forestry development provides certain favorableconditions.Qinghai in ancient times had a rich forest resources.Himalaya movement caused theuplift of the plateau, ice age coming, climate change, forest occurs several times and finallydisappeared, a large area of.Historical period, ancient Qinghai ancestors living in this land,the development of animal husbandry, agriculture.With the increase of population, agriculture,animal husbandry development, and alternately, a variety of war and frequent, while on forestuse, make limited forest was greatly upset.In particular, the Han, Tang, song, Ming and QingDynasties, in order to enrich cling to these areas, immigrants, the development of agriculture,deforestation, destruction of forest, grassland, grassland cause great damage, ultimately affectthe environment.The late Qing Dynasty to the Ma Bufang family ruled Qinghai, Qinghaiforest is almost gone.Qinghai forest destruction, the serious soil erosion, land desertification trend, waterconservation capacity decreased, caused the aggravation of zoology environment, forming a "bleak hills irrigation, Aji Chisato, boundless" status, therefore, forest water conservation,soil conservation, windbreak and sand fixation effects of ecological benefit get deeperunderstanding, therefore, to protect the forest is a pressing matter of the moment.The templeof forestry and the environment protection, and the constant, the ecological protectionfunction is everybody’s consensus, Qinghai multi-ethnic, multi-religious, many temples infavorable conditions, no doubt on the forestry and environmental protection will play agreater role.Through the understanding of Qinghai geographical environmental changes affect forests,lush and degenerative change, so we must have a profound understanding to the forces ofnature is infinite.While the forest, in addition to natural effect, historical period, the role ofhuman activity is the main results, the results in that era, is on the whole the destruction of theforest, to the forest restoration, must reduce population, less human activities, but also to helprepair the ecological, returning farmland to forests and grasslands, exit not suitable forplanting agricultural hillside, grass and tree planting.At the same time, to recognize humanlife, the production activity, is influenced by the local natural conditions, human should beinvolved in adaptation to the local natural environment of production activities, and todevelop and adapt to living habits, to Chinese ancient agriculture "to" theory as a guide, inancient China "the unity of heaven and man" under the guidance of the ideology, traditionalregression, for human life and production can be recycled, walking the road of sustainabledevelopment.
