摘要
为保护公园绿地的物种多样性和生态平衡,根据金银湖公园植物多样性植物现状,制定实地调查等方案,利用现有资源对武汉市金银湖湿地公园植物群落的多样性进行调查。调查选取8个样方,利用典型样方法,实地踏查,记录样方内植物的情况。并计算出物种的丰富度指数、多样性指数、均匀度指数、频度以及重要值指数。研究发现:全园植物共61科102属120种。其中乔木26科42属49种,灌木23科29属32种,草本21科32属36种,竹类1科2属2种,藤本1科1属1种。Pielou均匀度指数草本层>乔木层>灌木层;Margalef丰富度指数乔木层>灌木层;Shannon-Winner多样性指数乔木层>草本层>灌木层,说明公园中草本层均匀度高,乔木层物种丰富高,灌木层物种丰富度和均匀度均较差。栾树为公园乔木层的优势树种,是武汉市优良的园林乡土树种,建议在武汉市各大公园运用推广。
In order to protect the species diversity and ecological balance of park green space,according to the current situation of plant diversity plants in Jinyinhu Park,a field survey and other programs were developed to investigate the diversity of plant communities in Jinyinhu Wetland Park in Wuhan using existing resources.The survey selected eight sample squares and used the typical method to conduct on-the-spot investigations to record the situation of the plants in the sample.The species richness index,diversity index,evenness index,frequency and important value index were calculated.The study found that there are a total of 120 species in 102 genera and 61 families in the whole park.There are 49 species of 42 genera and 26 families of arbor,23 families,29 genera and 32 species of shrubs,36 families,32 genera and 36 species of herbaceous plants,1 family,2 genera and 2 species of bamboo,and genus genus.Pielou evenness index herb layer>tree layer>shrug layer;Margalef richness index arbor layer>shrub layer;Shannon-Winner diversity index arbor layer>herb layer>shrub layer,indicating high uniformity of herb layer in park,arbor layer species Rich and high,shrub layer species are poor in species richness and uniformity.Eucalyptus is the dominant tree species in the park arbor layer.It is an excellent garden native tree species in Wuhan.It is recommended to be promoted in major parks in Wuhan.
