摘　　要：2016年1月对洱海湖滨缓冲带内的植被进行了详细调查,结合现有资料和调查结果,运用植物地理学手段将结果进行多样性计算和聚类模型等,量化分析了洱海湖滨缓冲带内植物群落结构和多样性。结果表明:共采集鉴定到维管植物56科144属199种;包括挺水植物、浮叶植物、漂浮植物、沉水植物、湿生草本和乔灌木6个群落类型;有柳-叶子花-紫茎泽兰群从(Salix sp.-Bougainvillea spectabilis-Ageratina adenophora)、池杉-鹅掌柴-芦苇群从(Taxodium distichum var.imbricatum-Anemone flaccida-Phragmites australis)、麦冬-紫茎泽兰群从(Ophiopogon japonicas-Ageratina adenophora)等7个群丛;有12个分布型和10个变型,植物地理分布和组成的复杂程度较高。Based on an investigation of vegetation in the Erhai lakeside and buffer zone in January 2016 and other available data, the plant community structure and diversity within that area are quantitatively analyzed using the theory of plant geography and plot survey. The results show the followings. 199 species belonging to 144 genera in 56 families are found in the Erhai lakeside and buffer zone. There are 6 community types, including emergent macrophytes, floating-leaved plants, floating plants, submergrd macrophytes, wetland plants, arbor, and frute. The wetland holds 7 associations, such as Salix sp.-Bougainvillea spectabilis-Ageratina adenophora, Taxodium distichum var. imbricatum- Anemone flaccida- Phragmites australis, Taxodium distichum var. imbricatum- Anemone flaccida- Phragmites australis. Ophiopogon japonicas-Ageratina adenophora. There are 12 distribution patterns and 10 variants. The distribution and composition of plants are complex.
