For discussing the cave-reservoir,development characteristic and its dominant factor of lower-middle Ordovician in Tahe Oilfield,analyzing some data in Ⅷ block,such as: core,well drilling,logging,and seismic systematically,by using identifying reservoir,comparing well tie,analyzing section of seismic,and covering paleo-physiognomy.

Based on the detailed investigation of geological hazard in Danba County and combined with its current status,this paper analyses the development characteristic and the occurrence cause of the hazards.

Study of development characteristics of carbinate reserevoirs in the Lower Pleaozoic Dongpu Depression;

The development characteristics of macro-topography of arid and semiarid areas in northern China;

Geologic structure patterns and development characteristics of population landslide;

The paper surmmarizes the development features and distribution rules of the exposed subsidence pillars in Caocong Coal Mine of Huozhou mine area and makes the prediction analysis in the virgin area.

On the basis of making systermaticaly study of historical materials and remote sensing and investigating informations, the developing characteristics of the infuencial factors to the sensitivity of landslide, rock and geological structure, geomorphology, climate and human activity etc.
