【摘要】：黄河流域所属的诸省区均为粮食主产区和粮食平衡区,沿黄省区粮食生产事关流域乃至全国的粮食安全。从国家对黄河流域粮食安全定位出发,分别分析了现状和人口高峰时期流域粮食生产情况,研究了粮食安全存在的问题及解决粮食缺口的对策,提出了保障流域粮食安全必须立足流域自身解决的结论。从气候条件、水土资源条件等多个方面分析了黄河流域后备耕地资源潜力,并利用遥感、GIS解疑与现状典型调查等技术方法,研究确定了不同高程条件下可新增耕地规模,为黄河流域未来一定时期土地资源开发和保障流域粮食安全提供了技术依据。
[Abstract]:All the provinces and regions of the the Yellow River basin are the main grain producing areas and the grain balance areas. The grain production along the Yellow province is related to the grain safety of the valley and even the whole country. From the national food security in the Yellow River basin are analyzed respectively. The orientation of the grain production situation in present and in the peak period of population, food security problems and Countermeasures of the food gap, the food security must be based on watershed basin itself to solve the conclusion. From the aspects of climate, soil and water resources condition analysis of reserve cultivated land resources in the Yellow River River Basin using remote sensing and GIS potential, and questions and current situation of typical survey methods, research to determine the different height under the condition of new arable land scale, provide the technical basis for food safety in the Yellow River basin in the future a certain period of land resources development and protection basin.
