以福州市5个具防护、游憩、观赏三个典型功能特征的公园为调查对象,对公园植物群落分布特点及多样性进行系统的调查,分别应用物种丰富度指数(Richness index)、多样性指数(Shannon-Wiener index)、优势度指数(Simpson index)、均匀度指数(Pielou index)对调查结果进行分析。结果表明:在调查范围内,共记录56科81属108种,其中乔木59种,灌木27种,草本22种。公园植物物种多样性特征总体表现为乔木层>灌木>草本层。公园作为城市绿化建设的重要组成部分,建议在提高公园植物多样性建设方面应借鉴自然群落、模拟自然生态系统。
Taking five parks with typical functions of protection, recreation and ornamentation in Fuzhou as the investigation objects, the distribution and diversity of plant community in the park were systematically investigated. The species richness index, diversity index Shannon-Wiener index, Simpson index and Pielou index were used to analyze the survey results. The results showed that a total of 108 species belonging to 81 genera and 56 families were recorded in the survey area, of which 59 were arbors, 27 were shrubs and 22 were herbs. The characteristics of plant species diversity in the park are as follows: arbor layer> shrub> herb layer. As an important part of urban afforestation construction, it is suggested that the park should learn from natural communities and simulate natural ecosystems in improving the plant diversity in the park.
