INTERGRATED ANALYSES 
The rangeland in Zhenyun county occured 
more than one — third of total area due to 
deforestation in the past three decades. It 
is interested for goverment to find out by 
LIS where the rangeland is suitable for 
farming coincided with five conditions as 
following: 
1. The elevation is less than 1000 me- 
ter above sea level. 
2. The slope is less than 20 degree. 
3. The slope exposed to the sun. 
4. The soil beyongs to the alumo — 
725 
siliceous and iron —siliceous yellow soil. 
5. Non karst area. 
In this case, analysis was concerned multi- 
ple spatial and non —spatial data sets in an 
integrated manner by LIS deferring to the 
function of Automap or CAD. As a result, 
27 thousand Mu (15Mu = 1Hectare) of 
rangeland is suitable for farming in Wuyan 
village which corresponds 11% of total 
rangeland.
