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.

Northwest Territories are important constraints, the reduction of agricultural land, agriculture,
the substantial loss of population, agriculture, infrastructure damage, agricultural ecological
environment and the poor. Based on this, the north-west areas of the process of agricultural
drought introduced varieties, select a variety of agricultural disaster mitigation technology. In
this paper, the Northwest Territories to explore the Ming and Qing Dynasties of natural
disasters on agricultural production hazards, damage the rural economy and livelihood of the

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.
