摘　　要：选择昌黎黄金海岸作为研究区域,对刺槐林、杨树林和刺槐杨树混交林3种典型沿海防护林群落进行调查,采用物种丰富度指数、Shannon-Wiener指数、Simpson指数、Pielou指数和Margalef指数进行了生物多样性分析。结果表明:(1)调查共发现10种木本植物和13种草本植物,分属17科20属,其中优势乔木有刺槐、毛白杨、桑树等,优势灌木为紫穗槐;优势草本植物有茜草、鸭跖草、马唐草等;(2)对生态系统不同层次生物多样性进行比较得出,草本层明显高于灌木层和乔木层;(3)生物多样性水平排序为:混交林>杨树林>刺槐林,混交林具有较高的生物多样性水平,因此未来沿海防护林建设应以发展混交林为主。Three typical coastal shelterbelt communities of Robiniapseudoacacia forest, Populus forest, Robiniapseudoacacia and Populus mixed forest were investigated in Changli Gold Coast. Species richness index, Shannon-Wiener index, Simpson index, Pielou index and Margalef index are used to analyze biodiversity. The results showed that:(1) there were 10 species of woody plants and 13 species of herbaceous plants, which belonged to 17 families and 20 genera. The dominant herbaceous plants are Rubia cordifolia, Commelina communis, Digitariasanguinalis, etc.(2) The herb layer was significantly higher than shrub layer and tree layer.(3) The order of biodiversity level is mixed forest > Populus forest >Robiniapseudoacacia forest. Mixed forest has a high level of biodiversity, so the future construction of coastal shelterbelt should focus on the development of mixed forest.
