查询词典 The Evergreen Tree

The species diversity of Dipentodon sinicus communities in Yushe National Forest Park of Guizhou province was studied based on the quadrate method. The results showed that Rosaceae, Ericaceae, Betulaceae, Fagaceae, Theaceae, Lauraceae, Caprifoliaceae, Cornaceae were the dominant families in D. sinicus communities of Yushe National Forest Park. In the 10 sample plots, there were 8 which were absolutely dominated with D. sinicus population, the importance value came up to 135.69 on average, and it was far higher than the others. For D. sinicus communities, the abundance index (2.847), Simpson index (0.601), Shannon-Wiener index (1.523), probability of inter-specific encounter (0.601) and species evenness (0.569) of the tree layer were lower than those of the shrub layer (5.580, 0.830, 2.377, 0.829, 0.672, respectively) on the whole. It markedly showed a species diversity characteristic of the mixed broadleaved evergreen and deciduous forest in middle subtropics. In the 10 sample plots, the species diversity level of Q1 was the highest, followed by Q3, Q5 and Q6 was the lowest.

摘要运用样方法对贵州省玉舍国家级森林公园稀有保护植物十齿花群落的物种多样性进行了研究，结果表明：玉舍国家级森林公园十齿花群落以蔷薇科、杜鹃花科、壳斗科、桦木科、山茶科、樟科、忍冬科、山茱萸科等为优势科；10个样地中有8个样地以十齿花种群占绝对优势，其平均重要值高达135.69，远远高于其它种群；十齿花群落乔木层物种丰富度为2.847、Simpson指数为0.601、Shannon-Wiener指数为1.523、种间相遇机率为0.601、均匀度指数为0.569，总体上均小于灌木层(分别为：5.580、0.830、2.377、0.829、0.672)，表现为较明显的亚热带常绿落叶阔叶混交林的物种多样性特征。10个样地中，Q1的物种多样性程度最高，Q3次之，Q5和Q6最小，多样性程度最低，10个样地的物种多样性排序为Q1＞Q3＞Q9＞Q7＞Q2＞Q4＞Q10＞Q8＞Q5＞Q6。

The study shows that: evergreen broad-leaved species during the middle and later period succession have better adaptability under the different light surroundings, such as Elaeocarpus glabripetalus, Ilex integra, Photinia prunifolia, Cinnamommum camphora. And Fluorescent Characteristics also verifies the above result. The experiment results indicate that: PSⅡreaction centers of majority tree species are not marked oxidized under the full light surroundings. Photosynthetic electron transport activity can maintain highly, in this way, it is helpful to enhance radiant energy dissipation and thus dissipate excess light energy. That is to say, the increase of non-photochemical quenching coefficient can conduce to protect PSⅡ, and mitigate the effect of high light on photosynthesis.

研究发现处于演替中后期的常绿阔叶树种幼苗，对光环境的变化均有着较强的适应能力，秃瓣杜英、全缘冬青、小叶铁冬青、桃叶石楠、香樟等树种的表现尤为突出；荧光特性的研究也应证了这一观点，测定结果表明多数树种的PSⅡ反应中心并未受到明显氧化破坏，在全光照条件下仍能维持较高的光合电子传递活性，能通过提高非辐射性热耗散，消耗PSⅡ吸收的过剩的光能，从而保护PSⅡ反应中心免受因吸收过多光能而引起的光氧化伤害。

The results were as follows: 1 There were 7 133 trees, belonging to 23 species and 18 genera and 13 families, and their average DBH, crown and height were respectively 27.59 cm, 4.10 m and 6.94 m. In general their average crown was relative small. 2 S, H (Shannon-Wiener index), and D of biodiversity index were small, and there were the obvious difference in those indexes among different streets, which suggested that there were certain monotone of the tree species and structure layer. 3 The dominant species mainly consisted of evergreen trees that were Ficus virens var. sublanveolata, Ficus benjamina, Roystonea regia, Terminalia hainanensis, T.

结果表明：1梅州城区行道树共有13科18属23种7133株，其平均胸径、平均冠幅、平均树高分别为27.59cm，4.10m，6.94m，总体上看，平均冠幅偏小；2物种丰富度指数S、Shannon-Wiener指数H和Simpson指数D偏小且各道路间差异明显，说明各道路行道树存在一定程度的物种单一性、层次的单调性；3梅州市城区行道树优势树种是大叶榕、垂榕、大王椰子，次优势种为海南榄仁、阿珍榄仁、阴香，它们是梅州城市街道绿化的好树种。

To investigate the spatial-dependence of heterogeneity at multiple scales for a community, we selected a representative plot of 100 m×100 m in the mountainous evergreen and deciduous mixed broad-leaved forest in Sichuan, southwest China (102°50'E, 30°02'N).The location of every tree was mapped by compass, and all-scale analysis of spatial structure of forest community was conducted by the method of PCNM (principal coordinates of neighbor matrices).

为了解植物群落在多尺度下的空间变异规律及其对空间尺度的依赖，以川西南山地阔叶混交林为对象，在有代表性的地段设立100m×100m样地，采用传统的罗盘仪对树体的相对空间位置进行定位，运用主轴邻距法(principal coordinates of neighbor matrices， PCNM)对群落空间结构的多尺度（100m内）特征进行了研究。
