An assessment index system of land use suitability in the Shanghuang experimental area was established based on the characteristics of the area and the experts'advices

and the quantitative grade and weight of each index for the land suitability assessment were acquired using expert scoring method.The experimental area was divided into 185units

and the spatial and attributive database of the 185units were established using ArcView 3.2software.The land use suitability of each unit was analyzed using spatial overlay analysis function and comprehensive index method.Results showed that the largest area in the experimental area was the land suitable for grassland

about 419.04hm2(52.31%);the second

for agriculture

about 195.35hm2(24.39%);and the smallest

for woodland

about 46.8hm2(5.84%).the area of the land suitable for both grassland and woodland was 139.86hm2(17.46%).Result from the assessment could provide a data basis for determining the best land use plan of the experimental area.
