选择南京近郊2处自然湿地为研究对象,采用GPS定位、野外标本采集、Braun-Blanquet多盖度等级法和Shannon-Wiener物种多样性、Simpson生态优势度和群落均匀度指数研究南京湿地植物群落的种类组成、群落类型及其数量特征。结果表明南京湿... 选择南京近郊2处自然湿地为研究对象,采用GPS定位、野外标本采集、Braun-Blanquet多盖度等级法和Shannon-Wiener物种多样性、Simpson生态优势度和群落均匀度指数研究南京湿地植物群落的种类组成、群落类型及其数量特征。结果表明南京湿地有维管植物104种,隶属于93属45科,其中有国家Ⅱ级保护植物4种,包括水蕨、野大豆、野菱和莲;属和种的地理成分分析表明,该区维管植物区系以温带成分为主,同时热带成分也占一定的比例;该区湿地植被分为3个植被型,3个植被亚型,16个群系;湿地植物群落的物种多样性指数偏低,其中七里河湿地的物种多样性高于滁河入江口。根据南京湿地维管植物群落的特征,并结合当前存在的问题,提出南京近郊自然湿地的保护对策。 展开更多

Status and trends of biodiversity components in Republic of Macedonia are presented in this article. The monitoring of biodiversity components is conducted according to the criteria of SEBI 2010 (Streamlining European 2010 Biodiversity Indicators) for establishment of consistency at global, regional, EU and national indicator level. Two core segments of the Biodiversity Strategy and Action Plan of Republic of Macedonia are presented as well as the draft list of biodiversity indicators. Ecosystems and biotopes (presented with plant communities) are explained from which 30 Corine habitat classes are identified for the Republic of Macedonia. The number of endemic and endangered species from different taxonomic groups of vascular plants, fungi, fauna, and Emerald species with European importance are presented. Agro-biodiversity, structure of agriculture land, autochthonic breeds of domestic animals as well as the network of protected areas in Republic of Macedonia are presented. At the end conclusion remarks are given for future necessary activities at national and international level regarding monitoring and conservation of the biodiversity. 展开更多
