made for economic prosperity. At the same time, some
man-made natural disasters have been paid more and more attentions , so the research on hydraulic
characteristics of the river in recent years has been put on the agenda. Considering the ecological
environment, flood control, pollution prevention and control method, and in view of the perspective of
the urban landscape as well as the national strategic plan for sustainable development, the research the
hydraulic characteristics of river and making river reasonably repair and ecological reconstruction will
become a general trend, because that is a kind of remediation measure for human to be done
unreasonable exploitation, and it also will be the strong protection of river resources and sustainable
model for better using river resources in the future.

Group headed by
Cao Cao, Shuzhong Group led by Liu Bei, Jiangdong Group led by Sun Quan. The
political bloc led by Cao Cao had the most abundant strength and talents came forth in
large numbers. During the long-term expedition two major factions within formed:
Ru一Ying Group and Qiao Pei Group. Ru-Ying Group charged civil service mainly and
Qiao Pei Group was mainly made up of generals. These two groups had a long-term
punitive expedition since Cao Cao fought against Dong Zhuo. Finally they unified
vast areas of Northern China and carried out fruitful management, which avoided
serious damage in the region by a long war and laid a good economic, political and
military foundation for the unification of China in the future.
Cao Cao fought against Dong Zhuo at the beginning, seizing Yanzhou, Zhangxiu,
Xuhuai, Guandu, the four states, Wuhuan and Jingzhou, beat the seemingly invincible
powerful opponents one after another. His forces got stronger and stronger. The two
major political groups of Cao Wei supported Caocao on political and military aspects.
Because these two groups represented the interests of their own, inevitably
buried hidden dangers of can get on well with in adversity but can not share wealth.
Ru-Ying Group is represented by the family of Han who was in the name of
safeguarding the rule of the Eastern Han dynasty but to protect their interests. They
can support Cao Cao's domination, but resolutely oppose his taking over Han dynasty.
Qiao Pei Group on behalf of Cao Cao's family numbers who wished to gain greater
benefits through Cao Cao's taking over Han dynasty.
AD 209 years, The Battle of Red Cliff, which was Cao Cao's great cause of
reunification of the most important ended in failure. As the highest strategic staff
groups, Ru Ying Group throughout the campaign process simultaneously
inconceivable aphasia, and the army of Cao Cao was defeated. Cao Cao became
unable to dominate the country again in the rest of his life. This result was what Sun
Quan, Liu Bei would like to see, Ru Ying Group was also willing to see it. From the
historical records there was no record of staff at the Advanced Medium's death to give
people the impression that Ru-Ying Group seemed to have known the defeat in advance.
When Cao Cao was still alive, Qiao Pei Group holded the upper hand. But after
the death of Cao Cao, Ru-Ying Group strongly supported Cao Pi to be the king.
Finally Chen Qun put forward "Jiupinzhongzheng system", which established the
family of Han's political monopoly. The two major political groups gradually moved
towards a balance.
After the death of Wei Ming King, the two major political groups split from
co-operation, eventually formed a situation of endless immortality. Cao Shuang and
He Yan of Qiao Pei Group were launched by Sima Yi through Gaopingling case when
the situation was good. Sima Yi killed Cao Shuang and holded military and political
power in the country. He cruelly blowed members of the Group Qiao Pei through a
series of charges against them. Then, Jin Dynasty took place Wei. Ru-Ying Group
obtained a comprehensive win. While Qiao Pei Group after its three generations with
a heavy heart exit stage of history.

e distinctive features in Western and Eastern of
Qinghai's natural disaster in history which based on the historical materials and studied the
Interaction Relationship Between the natural disasters and social-economic development, we
used the theory and analysis method from the research area of disaster history and agricultural
history, try to have a comprehensive investigation between the natural disasters and
social-economic development in the history of Qinghai.
Firstly, we divided Qinghai into two parts: the eastern and the western, under the study of
the geographical features of Qinghai. We summarized the natural disaster of the eastern part
mainly as flood, drought, hailstone and frost with distinctive features of variety, continuity
and growth accompany while the western is mainly as earthquake and snow disaster with
distinctive features of unexpected and severity.
Secondly
,
as the great influence on agriculture and the resulting changement in
agriculture is most profound, so the progress in agriculture sciences is related to withstand the
natural disaster in some ways. The paper discussed the natural disasters affected Qinghai's
agriculture in history, from the aspect of seed selection
、
production
、
processing and storage
to invest the development of mitigation techniques in this area. And for the livestock we
investigated in two sides bred of livestock and prevention of livestock, furthermore we
invested the mitigation techniques which full of geographical characteristics.
Thirdly, the article investigated the relationship between natural disasters and the
economic fluctuation in Qinghai from the perspective of the change in population and grain
price. And then, we analyzed the influence on regional industrial structure from the aspect of
expansion in rural areas, the relationship between agriculture and animal husbandry,
disaster-relief crop introduction and the structure of animal species. In the view of pastoral
economic exchange, we studied the interaction relationship between the natural disasters and
economic development.
Finally, we studied the interaction relationship between the natural disasters and social
development in Qinghai. What is more, we analyzed the policy which includes grain storage,
relieved and help the people in disaster , reduced taxes to control the disaster in history. We
wish these could be helpful to the prevention and control of natural disasters in Qinghai today.
