Sui And Tang Dynasties Qinghai Grasslands War And Ecological Environment

Sui and Tang dynasties were an important chapter in our history. The tactics of the dynasties extended territory at this time,and in the Northwest Territories distributed a few mature Minority forces,for example:TuYuhun, Tibet, Party items. In the early of Sui, TuYuhun often harass the North West Frontier of Sui,when the Sui could not think about it. During the reign of Sui emperor Yangdi,the Sui attacked Tuyuhun. Tuyuhun in the middle of the Tang Dynasty and Tibet,the important position is the main reason of the warfare.For the Tang Dynasty, controling Tuyuhun, which means controling the South Road of Silk Road(also known as the Qinghai Road, Tuyuhun Road), which keeps abreast with the North Road of Silk Road (also known as Hexi Road), lay the foundation for the further Western. More importantly is the defense, if the majority of the Tibet occupatied the region of TuYuhun, especially near Chiling,the Tibet can be reached Chang'an, with the speed of the Tang Dynasty cavalry,in six or seven days. So Tuyuhun is the barrier of the Tang Dynasty in northwest, losing Tuyuhun, the Longyou region could be facing a great threat.So to the Tibetan controls Tuyuhun also has important significance.The wars were quite frequently on Qinghai Grassland in Sui and Tang Dynasties.According to statistics records, there were 7 times Large-scale war between the Sui and Tang Dynasties and the Tuyuhun,3 times between Tibet and Tuyuhun,12 times between Tang and Tibet.ln war, armies and horses had caused tremendous damage on grassland. The pasture which was trampled by the military would go through a long period of time to recover.If the grass was severely damaged in the ecologically fragile grasslands of Qinghai,it would be even more difficult to recover,even it was possible to make the region sandy or desertification. Besides seting fire on the grasslands, farming on grasslands were very harmful to the grasslandes. Agriculture and animal husbandry frequent alternation, land reclamation, cultivation, abandoned, grazing, desertification, and then cultivated had affected the equilibrium of ecosystem.When farming peoples rule this region,they were farming, when the nomads dominate this region, they were grazing. The reclamation of land, once abandoned, would speed up the process of desertification.Although the Qinghai grasslands is vast and river cross-flow, but the high altitude, cold climate, vegetation, short growing season, Pasture, with a low temperature radiates and natural conditions of the group is generally low and animal husbandry, the conditions of relatively low. war, repeatedly, to the destruction of grassland productivity, in varying degrees on the environment here has had a negative impact. Cumulative impact of these destructive, agricultural cultivation of grassland in Qinghai with the rapid development of grasslands to increase the carrying capacity of grasslands in the region.The development of ancient Chinese society with a certain periodicity, influence of this cyclical factor was the great destruction of the ecological environment-to restore the cycle. Direct driving force for war, after complete the'ecological migration', people will to survive and develop in a new system of social organization and the natural environment. Following rapid population expansion, land lot development, and society progress were Deteriorating ecological environment, ecological resources, quality and decreased, people's living environment and resources are severely limited,catalytic role in the war, people were easily carried out under another new cycle of production.Historical period to immigrant settlement as the mode of development of the west are the extensive way. despite its military and political significance, economic and environmental significance is difficult to word. Such as the overlay of climate change, it is vulnerable to ecological degradation of the junction. And military activities related to the natural environment and agricultural production caused by the reaction, most destructive. We can see from military activities and eco-environment interaction, a better understanding of the marxist theory of alienation.Historical period of Western Development and ecological relationship between environmental change, inspired us in the future development policies formulated, must consider the characteristics of the local ecological environment changes, adapt to changes of environment, especially a scientific horizon to look at and judge all land development activities. The western region development of ecological conservation should be a long-term。...
