The results showed that 429 species of oil plants belonging to 239 genera and 90 families distributed in this area. There were eight dominant families of oil plants with more than fifteen species,which were Fabaceae, Rosaceae, Lauraceae, Euphorbiaceae, Caprifoliaceae, Liliaceae, Celastraceae and Rutaceae. There were two dominant genera of oil plants with more than ten species ,which were Viburnum and Lindera. The life-form of the oil plants was mainly woody. The distribution elements of the oil plants in this area were dominated by pantropical and cosmopolitan elements in the family level, pantropical and north temperate elements in the generic level,and mainly concentrated in East Asia and endemic to China at the species level. The oil plants in this region were abundant and versatile. There were 40 species belonging to 18 families and 22 genera with oil contents higher than 40%, which showed that the oil plants in Dehang scenic spot had great potential for resource development and utilization. Dehang scenic spot was consistent with Xiangxi in the characteristics of the oil plant resources, and was roughly the same with Wugongshan Region, Jinggang Mountain nature reserve, Lushan nature reserve and Huping Mountain national reserve in the distribution elements of the oil plants. |
