| Abstract: |
| Based on the demands of precious legume forest species，such as Ormosia henryi，O. hosiea and
Dalbergia odorifera habit and taking the woodland，orchard，meadow，and some unused land in Fujian as the research
object，a suitability evaluation index system of precious legume forest species was established. The index system
included 14 relevant factors form four aspects: topography，climate，soil and social economic. Suitable land resources for
precious legume forest species were assessed by GIS technology，integrated with correctional weighting-multiplication
model. On this basis，non-planting areas were extracted from the land-use map，the layout of precious legume forest
species in Fujian was optimized based on the principle of＂suitable trees plantation on land＂with integrated technology
of the advantages of index method and K means clustering analysis method. The results of regionalization included three
grades of preferential planting area，secondary preferential planting area and general planting area. The results of above
partitions were analyzed and optimizing arrangement map of precious Legume species plantation in Fujian was drew by
GIS technology. |
