Speciality researching on water quality of the Jing River and the Wei River;

According to hydrographic data, the average runoff volume of Jing River (from 1932 to 1997)is only half of that of Wei River (from 1950 to 1997), but the suspended sediment of Jing River is 2.

This paper puts forward some solutions to the serious disasters of landslides visiting the southern-bank of the lower reaches of the Jinghe river,which is based on an introduction to the characteristics of landslides,the classification of tableland slopes through calculating the stability coefficient,and a through analysis on the paroxysmal and short-term variable causes for landslides.

In the next place,on the basis of dynamic water balance simulation of Jin river basin based on the GRID,the natural water renewability .
