邢台市宁晋县汪洋沟公园植物调查及多样性分析

摘要植物调查是研究植物群落及植物应用的重要环节，通过调查、分析、研究可以得出相应的特征现状，为植物的应用保护等方面提供基础支撑。本文调查研究对象为宁晋县汪洋沟公园植物，以宁晋县汪洋沟公园为研究区域，通过前期大量查阅文献并运用实地考察，运用数据整理分析法来对公园植物进行具体分析。随机选取公园样地4处，面积均为20m×20m的样地作为研究对象。结果表明：(1)调查统计中汪洋沟公园4块样地植物总共26种，分别隶属于16科24属。其中乔木类植物11种，灌木类植物9种，草本类植物6种。其中，观干类植物和观果类植物较少。汪洋沟公园重要值排名前三的木本和草本植物分别为连翘、大叶黄杨球、悬铃木、鼠尾草、白车轴草和美女樱。(2)对公园绿地的26种植物进行多样性分析。通过多度、相对多度、频度、相对频度、重要值来体现每种植物。并通过以上数据计算出乔木层、灌木层、草本层的物种多样性等等。四块样地的Shannon-Wiener多样性指数的排序为：样地三>样地二>样地一>样地四。公园四块样地总体木本植物种类应用较多，群落稳定性较高。关键词：植物群落；数据分析；园林绿地；多样性分析ABSTRACTPlant investigation is an important part of the study of plant communities and plantapplications,and the corresponding characteristics and status quo can be obtained throughinvestigation,analysis and research,which provides basic support for the application andprotection of plants.Taking Wangyanggou Park in Ningjin County as the research area,this paper used datacollation and analysis to analyze the plants in the park through a large number of literaturereviews and field investigations.Four sample plots of park plots,all with an area of 20m x 20m,were randomly selected as the research objects.The results showed that:(1)In the survey statistics,there are a total of 26 species of plants in the 4 plots ofWangyanggou Park,which belong to 16 families and 24 genera.Among them,there are 11species of arbors,9 species of shrubs and 6 species of herbaceous plants.Among them,there arefewer dry plants and fruit plants.The top three woody and herbaceous plants in WangyanggouPark are Forsythia,Boxwood Bulb,Suzuki,Sage,White Axle and Cherry Blossom.(2)Diversity analysis of 26 species of plants in the park's green space.Each plant isrepresented by multidegree,relative degree,frequency,relative frequency,important value.Fromthe above data,the species diversity of the arbor layer,shrub layer,herbaceous layer and so onwas calculated.The Shannon-Wiener diversity index for the four plots is ranked as follows:plots3>plots two>plots 1>4.The four plots in the park have more woody plant species and highcommunity stability.Keywords:Plant communities;Data analysis;landscaped green spaces;Diversity analysis目录第一章绪论…1.1研究背景.1.2研究目的和意义......1.2.1研究目的，1.2.2研究意义…21.3国内外研究现状.……2第二章研究对象及研究方法.32.1研究对象32.2研究方法….32.2.1实地考查法。32.2.2文献查阅法42.2.3数据分析法.…52.3结果与分析..5第三章汪洋沟公园植物的综合分析.63.1群落物种的组成。.63.2植物数量特征及重要值分析.3.3植物多样性分析.83.4最终结果与分析…9第四章结论与讨论..165.1结论..165.2讨论…。175.2.1研究不足175.2.2未来展望.17参考文献….18致谢.19
