黄河流域多尺度区域界定及其应用选择

黄河流域涉及区域广阔、问题复杂多样，相应的研究内容较为丰富，存在空间研究范围和分区不一致的问题。立足于黄河重大国家战略目标任务和不同研究需求，考虑流域与沿黄行政区在资源利用-经济发展-生态保护等方面的关联性，将黄河流域空间研究范围界定为黄河流域区、黄河干流流经区、黄河流域涉及区和黄河全行政区，并对其他研究范围及分区进行了说明；从空间范围、研究内容、行政管理3个方面对比分析4种区域界定方案，明确了不同方案之间的联系和区别；依据针对性和目的性等原则，系统梳理了不同研究内容对空间范围的选择情况，解决了什么情况下可以或应该选择某个特定空间范围的问题。研究成果可为后续黄河流域相关研究提供统一标准和参考依据。

Multi-scale regional definition and its application selection in the Yellow River Basin

The Yellow River Basin involves a vast area, complex and diverse issues, and the corresponding research contents are relatively rich. There is a problem of inconsistency in the scope and partition of spatial research. Based on the Yellow River’s major national strategic objectives, tasks and different research needs, considering the relevance of the river basin and administrative regions in terms of resources utilization, economic development and ecological protection, the defined spatial research scope of the Yellow River Basin covers the Yellow River Basin, the administrative regions that the Yellow River mainstream flows through, prefectural regions involved in the Yellow River Basin, and the entire provincial regions that the Yellow River flows through, and other research scopes and divisions are also expounded. Then, four regional definition schemes are compared and analyzed from multiple aspects (i.e., spatial scope, research object and content, administrative management), and the relationship between different schemes is further clarified. According to the principles of pertinence and purpose, we systematically sort out the selection of different research contents on the spatial scale, and solve the problem of under what circumstances a spatial scale can or should be selected. The research results can provide a unified standard and reference basis for subsequent studies in the Yellow River Basin.
