The material sources of the Zhangxia Loess which is exposed on the terraces in Zhangxia of Changqing region of Jinan are complicated,including materials transported by northwestern current and eastern Bohai Bay current and the local pluvial sediments.

The probability curves of alluvial fan conglomerate reservoir have the characteristics of coarse-grained, wide-range and low-slope.

Based on the study of different hierarchical bounding surfaces and the transplantation of the Miall\'s idea in the complex reservoir of alluvial fans,a hierarchy analysis method is established,which is suited for the development precision on the inner structure of the alluvial fans.

On Nitrogen transform and hydro-geochemical characteristics of the Hun river alluvial and flood fan;
