七里海古泻湖湿地植被特征及其植物物种多样性研究

Study on Vegetation Characteristics and Plants Diversity in Qilihai Ancient Lagoon Wetlands

为了更好的了解七里海古泻湖湿地植被的现状,有效保护植物资源,采用样方法调查和分析了湿地植物的物种和区系组成、生活型构成、群落结构及其多样性特征.结果表明:(1)七里海湿地植物较为丰富,共69科、200属、290种,以草本植物占优势;(2)地理成分多样,除去世界分布属后,泛热带成分和北温带、旧世界温带成分占极大优势,湿地植物属的区系地理成分为显著的温带性质和一定数量的热带性质;(3)群落复杂多样,划分为5种植被型,计有22个典型群落,农作物、人工林、部分野生灌木和草本群落的多样性水平普遍高于野生藤本植物群落和水生植物群落,人工干扰改变了湿地植物多样性性质.

In order to understand more about the current situation of vegetation in Qilihai wetland and protect the plant resources effectively,the wetland plant species and their flora composition,life forms and community structure,and their diversity were surveyed and analyzed by the quadrat method. There were a total of 290 species of plants belonging to 69 families and 200 genus geographical compositions were abundant. Pantropic in Qilihai wetland,and the herbage were dominant. The elements, the North temperate elements and the Old World temperate accounted for a great advantage （excluding the Cosmopolitan elements ）,with the characteristics of the temperate zone and the trophic. The wetland vegetation could he classified into 5 vegetation types, and 22 typical communities. The diversity of crops ,artificial forest ,some wild shrubs and herbaceous communities were generally higher than the wild vine communities and aquatic communities. Artificial interference changed the nature of wetland plant diversity.
