Countermeasures and genesis of water and soil erosion at Emuer River Valley;

Hydraulic and thermodynamics factors analysis on ice dam formation in Emuer River;

Content of Air-borne Microbes Above Xining, Qinghai Lake and Geermu in Qinghai Provence;

The Throat of Entering Tibet: Research of Orienting City Position of Geermu;

The climatic characteristics were analysised base on meteorology observational data of Geermu and the purple cortex garlic growth s agriculture meterology conditions were analysised on the basis of it s growth characteristic,and suitable climate under the suitable climate the scientfic manage model were put forward.

With regard to the Ge Ermu city which has become a start point of the new line,opening the whole line of Qingzang railway is taking and will take grave effect on its resource exploitation、city development and industrial layout,in this paper researches about it.

The local earthquake wave velocity,mean wave velocity ratio and imaginary wave velocity are calculated according to the seismic data recorded by Ge ermu station from 1991 to 1999,and the crustal thickness is determined in Ge ermu area.
