In history;the central and local separatist all
valued the development of this area. During the Ming and Qing Dynasties,with the renewed
fighting in the northwest, coupled with the rapid growth of the national population, In order to
consolidating border defense and detenting Mainland population pressure,the land development of
this area resumevted,which impacted histoy development of this area very profoundly
Academic research in this area is more included in the academic research for the whole Hexi area
or the entire northwest region, special articles in this area are also mainly concentrated in the lower
reaches of Shiyang River, but these research the upper, middle and lower reaches of the river as a
whole rarely,the connection among the three is.very close essentially.So this object has larger space
to continue researching.
This text includes introduction and body text.the introduction introduces the writing
causes ,implication,and retrospects intellectual history, explains research objectives,Methods and
important and difficult points of this object at the same time.The body text divides into six
chapters.The first chapter analyzes the natural conditions and social infrastructure in this area.The
second chapter mainly deals with immigration status which Ming and Qing government organize
and encourage the population in the mainland move to this area,which provides manpower
resources for agricultural development in this area,and this chapter discusses effectiveness of the
immigration.The third chapter discusses construction of water conservancy which agricultural
development requires,and summarizes pearls and pitfalls of water conservancy construction in
this area during this period.The fourth chapter mainly deals with agricultural development in this
area during the Ming and Qing dynasties,This chapter begin by the reasons for agricultural
development and policies which the government urge and offer for, discusses region of agricultural
development, reclamation success and evolution of tonden in this area during this time.The fifth
chapter mainly discusses environmental problems that because of large-scale development in this
period,and analyzes performance, hazard and measures that local people inoder to protecting the
environment had taken.The sixth chapter summarizes experience and lessons those because of
large-scale development in this period during this time,and explains inspiration for today's
development.
Research of this object is primarily based on literature of the Ming and Qing Dynasties and local
records, and notes data that through field visits get, in order to make the discussion Speci.ficly and
reasonably.

y, military and culture in Ming Dynasty。The research on military
farming of the Ming Dynasty played the vital role of leading as to the
research on the outline the history of the Ming Dynasty. The Military
Farming in three states-- He Min and Tao-in Ming Dynasty, as the
epitome of the Ming Dynasty Northwest military Farming, has its
characteristics. He Min and Tao military farming not only has the
common characteristic of that period, but also has its unique distinguishes,
because which is located at the junction of the Han and other ethnic
groups, within the area lived many ethnic minorities. In this paper, the
author analyzes the relevant historical materials and uses theories and
methods of history and ethnology to explain the origin, development,
characteristics of the military farming. And the author discusses the
reasons why they declined in the later years and the impacts in a detailed
and intensive way. Based on local historical dates and combined with the
same period dates, the article analyze mainly the differences among the
three states from its preparation, operation, function and impact aspects
and deal with the military system of the Ming Dynasty, migration,
defense policy, minority administration and policy, economic strategies.

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.

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.

od of Warring States
(475-221 B.C.), attracting scholars' attention and becoming one of important schools then.
After Qin Dynasty, scholars determining to study agriculture carried forward good
traditions of Non自is in the Period of Warring States, enriched researching contents and
fields, and enabled Non自is to develop in depth. In finial, those determining to study
agriculture formed a group with researching agriculture as its distinguishing feature. What
the group researched included agricultural ideologies, techniques of farming and cropping,
methods of operation and management, measures of fighting and preventing agricultural
calamities. The whole group showed its own styles in valuing agriculture and concerning
people's livelihood. And those agricultural ideologies, science and technology, methods and
spirits composed Nongjia's culture, the cream of which can afford us lessons to solve
today's new problems.

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
affected farmers. By the six parts.
