描述: ral environments make the cultural dissemination possible. In archeological materials we can see plenty of Neolithic culture and Bronze culture,which may be nomads. Ywati, Wusun, Hun were lived here.Befor Han Dynastie ,the area was regarded as wild and woolly place.the Hun sprang up during Qin and Han Dynastie, Gansu Corridor became more and more imporant in military and politics affairs.

After long time Interaction,the two change the hisroy of this area.Although some rejection and degradation happened,the new trail was certainty. Agricultural civilization took new tools to the area,and finally the Silk Road was freely.It made a contribution to culture dissemination.However,the aggressive e x p a n s i o n m a d e t h e immigrate and armies too huge,and led the crisis of ecologyand resource. Qiang civilians uprising during the Eastern Han Dynastie made the land desertificated. The process was not at one stroke,but a long time. Rely on force was to set up a unified ,multinational country.

描述: 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.

西部干旱地区农户旱地种植行为实证研究
作者: 叶晶晶   来源: 南京农业大学 年份: 2010 文献类型 : 学位论文 关键词: 农户   旱地   水资源   决策   干旱风险  
描述: ncentrated v}}ith 85% of the total dry lands. and it is important for the national economy and the countr<0's strategic agricultural growth. Northwest arid areas basically depend on natural precipitation. water shortage has seriously affected the farmers practices. The decision of farmers to plant dry land is a two-stage decision-making behavior: They first have to decide whether to plant dry land, and then decide what kind of crops planted in the dry lands. It is essential to find effective ways to raise the enthusiasm of farmers planting and reasonable arrangements for dry land crop structure. However. ver}} few people study dry land farming practice from the perspective of water shortages.
全文:旱地农业生产关系到我国的粮食安全,旱地占全国耕地面积的60%,集中有全国85%旱地的北方地区更是成为了国民经济和国家农业增长的战略要地。西北干旱地区旱地灌溉基本上是以自然降水为主,干旱严重影响了农户的旱地种植行为,农户的早地种植决策是两阶段决策行为:他们首先要决定是否种植旱地,然后再决定在旱地上种植何种作物。研究干旱地区影响农户种植旱地的因素有利于寻求有效的途径来提高农户种植积极性和合理安排旱地作物结构是十分必要的,但是很少有人从水资源短缺的角度对农户的旱地种植行为进行研究。 基于以上背景,本文选择了水资源短缺比较明显的甘肃省张掖市民乐县为研究区域。文章通过干旱条件下分析影响农户种植决策的影响因素,对农户是否种植旱地的初始决策和如何选择旱地作物种类的二次决策进行实证分析,从而为提高农户种植积极性和指导农户合理安排旱地作物种植结构提出有效的政策建议。 全文分为五章:第一章是绪论,首先介绍了研究背景和问题的提出,然后阐述了研究的目的和意义,以及研究方法和技术路线;第二章主要介绍了本文涉及的重要理论基础和相关文献回顾。理论基础主要包括农户风险投资行为理论。文献综述包括水资源风险相关研究、农民风险偏好的相关研究、农户投资决策行为和影响农户决策的相关因素等内容;第三章首先回顾了甘肃省农业生产自然条件,然后分析了研究区域张掖市民乐县的水资源利用情况,最后对该区域的调查资料做了一个简单的描述。第四章首先根据前人的理论成果经过提炼提出了本文的研究假说,然后介绍了模型的选择和变量的定义,分析了变量的预期影响效果,然后分别利用二元选择Probit模型和多元排序选择Ordered Probit模型对农户是否种植旱地的初始决策和如何选择旱地作物种类的二次决策进行实证分析。分析发现,非农收入、土地产权、人均耕地面积在两个模型中都是显著的。土地肥力只对农户初始决策产生显著影响,地块数量、农机具价值、户主文化和年龄、地区分类变量对农户选择旱地作物种类的影响是显著的。第五章在实证分析的基础上进行总结,并提出了相关的政策建议。
