摘要

对南京市珍稀濒危植物的种类、分布、生境及濒危原因进行了调查和分析,并对主要种类进行了就地保存、迁地保存或就地-迁地保存实验。调查发现,南京市共有珍稀濒危植物17种1变种,隶属9科17属,主要分布在丘陵山地;人为因素是其濒危的主要原因。对明党参(Changium smyrnioides H.Wolff.)、短穗竹〔Brachystachyum densiflorum(Rendle)Keng〕及秤锤树(Sinojackia xylocarpa Hu)等种类的保护研究结果表明,采取一定的人为干预措施,可使南京市珍稀濒危植物的种群数量得到有效的保存和恢复。

Abstract

The species, distribution, habitation and reasons for rarity and danger of rare and endangered plants in Nanjing were investigated, in-situ, ex-situ or in-situ and ex-situ conservation experiments on some important species were also conducted. The results showed that there were seventeen species and one variety of rare and endangered plants belonging to nine families and seventeen genera, which mainly distributed on hill and mountain regionin Nanjing. The human disturbance factors were the main reasons for leading these plants to danger. The results of conservation researches on some important species, such as Changium smyrnioides H. Wolff., Brachystachyum densiflorum (Rendle)Keng and Sinojackia xylocarpa Hu, showed that the population size of rare and endangered plants in Nanjing could be effectively protected and restored by means of artificial intervention measures.
