| 摘 要： | 为了使内蒙古自治区的水文分区更加合理,本文根据全部水文因子表现的"集体效应",按照"从主、从众、从源"的原则,以能够集中反映能量、水分的分配与组合并相互转化的干旱指数为主要指标,划分大区;按地形、地貌、土壤、植被等下垫面因素的相似与相异的程度,划分小区.作出的成果,较之用单项指标进行分区,有了明显的进步,从而提高了分区的合理性.

| Abstract: | This paper gives new principle of hydrological area division in Inner Mongolia according to "collective effects of hydrological factors ".The big hydrological areas are divided mainly according to draught indexes that are able to reflect energy,water distribution and transformation.The small areas are divided according to similarity or difference of the factors such as topography,soil and vegetation.The division of hydrology areas by using the principles is more reasonable than one factor division principle... |
