| 中文摘要: |
| 为了掌握极小种群川柿(Diospyros sutchuensis Yang)的种质资源现状并评估其濒危等级,对川柿资源历史发现地及现发地——华蓉山、缙云山、江津四面山保护区进行了系统野外调查。结果表明：(1)当前历史发生地华蓉山已无川柿野生植株,缙云山有疑是川柿1株,而在江津四面山保护区发现少量植物。(2)江津保护区有3个分布点,共计6株,均为成年植株。(3)依据IUCN全球物种濒危等级评估标准,川柿应当被评为(EN,B2a)。 |

The results are as followings: There is no wild plant of Diospyros sutchuensis in Huarong Mountain now, the current history occurred.
