摘　　要：采用多元正交多项式回归分析方法 ,研究了黄河中游河口镇—潼关区间流域产沙与地理环境要素之间的耦合关系 ,在自然地带性、非地带性因子对流域产沙影响的响应机制和交互作用分析基础上 ,定量得到河潼区间流域产沙的极值区形成的环境要素复合临界。This paper studied interactions of environmental elements affecting sediment yield of drainage basins between Hekouzhen and Tongguan in the middle Yellow River by using the method of multi variant, polynomial formula regression analysis. Studies indicate that sediment yield in drainage basins is affected by compound interactions of natural zones environmental elements with other factors and complex actions. Based on the analysis of interactions of single and compound elements, the present paper quantitatively gives the compound threshold of environmental elements affecting sediment yield of drainage basins between Hekouzhen and Tongguan in the middle Yellow River by using the method of multi variant, polynomial formula regression analysis.
