| The oil plant resources in Jinggang mountain nature reserve were investigated through field investigation, sample collection, sample indentification and literature review.The results showed that 286 species,belonging to 162 genera and 71 families, were distributed in Jinggang mountain nature reserve. There were 13 species,10 genera and 6 families of gymnosperms, 269 species,148 genera and 62 families of angiosperms，and 4 species, 4 genera and 3 families of monocotyledon, taking a ratio of 20.88%、16.27% and 8.97% respectively in Jinggang mountain oil plants,and taking a ratio of 65.74%、40.81% and 35.14% in Chinese oil plants. The dominant families which had 10 or more oil plant species included 8 families. The oil contents in 71 species,belonging to 36 genera, 25 families, were higher than 40%. Jinggang mountain nature reserve distribution types of the oil plants were various and origin of ancient, and the temperate types were dominant, among which the north temperate zone, East Asia and North America disjunction accounted for a large rate. |
