Landslips in Sanchuanhe watershed in Shanxi Province aro classifiedand named by three indices of "slipbed". "stability"

and "slip volunme". Inthe investigation

the color synthesized landsat images in scale of 1:100

000maps in scale of 1: 50

000 and 1: 100

000

and the maps of geology

geomorphology

water system

plantation and soil erosion etc.

are taken asthe major resource of information. Then

by visual judgment the landslipsare determined in existence

type

stability and scale. The result showsthat the area of landslip are highly correlated with their lengthes and widthes. If the concerned data from the classification map of landslips distrition transformed in net of landslip is input to computer

controlled withmanage system of DBASE Ⅲ data base

the number

area and volume ofthe slips could be calculated

and ten special maps such as that of distribution intensity could be obtained

which would provide the information needed for the regional renovation and development.
