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：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

甘肃省黄河沿岸地区水资源承载能力分析: 作者： 刘建兰 来源： 兰州大学 年份： 2010 文献类型： 学位论文 关键词： 甘肃省沿黄地区 水资源 承载能力系统动力学; 描述： th, the demand of water resource is continuously increasing. That is to say water shortage has become a global problem. Water resources carrying capacity is the basis and prerequisite of regional socio-economic development, which is significant to realize the coordinated development of regional "water resources- ecological environment-socio-economy" composite system. So it has become the focus and hot topic in water science field nowdays.; 全文：水资源是人类生存和社会发展最重要的基础资源,随着世界各国经济和人口的增长,水资源的需求量不断增加,水资源短缺已经成为全球性问题。水资源承载能力对于实现区域“水资源一生态环境一社会经济”复合系统
