TOPOGRAPHIC ANALYSES 
Space data is the main information sources 
for GIS/LIS. Land information system 
(LIS) in Zhenyun county were consisted of 
not only TM data but other georeferences 
data such as geology, soil, topography, 
transpotation, population, administrative 
boundary, land use inventory etc.. The 
GIS/LIS software South Karst set (SKset) 
for micro computor 486/66 was developed 
by authors group in the last decade with 
both raster and vector data structure in- 
cluding the functions of environment dy- 
724 
fication on the terminal using existing sur- 
vey data and other georeferenced data in 
the GIS/LIS. Then the accuracy of inven- 
tory could be increased ranging from 594 
to 10% again.

Zhenyun county is consisted of 12 villages. 
One of the biggest village is in the vicinity 
of town called Wuyan. The cropland (non- 
irrigated) distributed in the different eleva- 
tions and slopes in Wuyan village overlaied 
by topographic elements analysis and land 
use inventory (table. 2). The slopes of 
cropland exceeding 15 degree occur 36. 4% 
of total cropland. This parts are easy to be
