Abstract: Based on the optimal structure analysis and optimal growing model curve estimation of the Jianhu shelterbelts, three scale scheme aiming at the study area was brought out. Applying the spatial analysis and statistics function of GIS, the spatial arrangement of shelterbelts of study area was accomplished. The result shows that the forest cover percent of study area was improved distinctly under the condition of optimization arrangement. The application of optimization arrangement of shelterbelts using GIS technology provides the straight and scientific foundation in shelterbelts management,
