| Abstract: | Based on survey of site factors and biological productivity of fire proof belt of ridge of Cangwu county, Guangxi province, the dominant factors affecting the biological productivity were screened by progressive regression analysis, and the mathematical model of biological productivity was constructed. The results showed that the dominant factors affecting the biological productivity of fireproof belt of ridge were elevation, soil thickness, content of stone and slope position. The sites were incorporated into three groups according to the mathematical model constructed, and the qualities of the sites were evaluated as well. The research provided a basis for tree species selection of fireproof belt of ridge. |
