南京市植物物种多样性现状及保护对策

通过对南京市域植被资料的搜集与实地调查,分析了南京市植物物种多样性。结果表明:南京地区高等植物共有2073种(含种以下等级),隶属221科、899属;其中乡土植物158科、609属、1 333种;资源植物中观赏植物1068种,药用植物760种,油料植物90种,纤维植物89种;国家Ⅲ级以上保护的濒危物种64种。整体上南京植物资源较为丰富,有许多具有很好的开发利用前景,植物物种多样性的保护需进一步融入生态环境建设,挖掘乡土植物资源,合理利用资源植物,研究利用重要濒危植物。

Current Situation of Plant Species Diversity in Nanjing and Its Conservation Strategy

In this paper,the authors made a full data collection and field investigation on vegetations in Nanjing City,and analyzed plant species diversity in Nanjing.The results showed that there were 2073 species（including subspecies） of higher plants,belonging to 899 genera and 221 families,including 1 333 species,609 genera and 158 families of indigenous plants.There were 1 068 species of ornamental plants,760 species of medicinal plants,90 species of oil plants,89 species of fiber plants.The endangered species under the national Ⅲ or above protection was 64 species.Generally,the plant resources are abundant in Nanjing and a large number of species have potentially higher development and utilization value.The protection of plant species diversity needs further integration into ecological environment amelioration,and it is supposed to tap native plant resources,rationalize the use of these plants and study and utilize important endangered plants.
