Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.

结果表明：（1）氮素添加提高了土壤中NO3—- N等可利用资源的含量，增加了植物群落植被的盖度，减小了植被的透光率，随着施氮量的增加群落中物种丰富度显著降低（P 0.001）；（2）氮素添加显著改变了植物群落地上生产力（P 0.05），随着施氮量的增加地上生产力呈现先增加后降低的变化趋势，各功能群中禾草生物量显著增加，而杂草和豆科生物量随施氮量增加逐渐减少；（3）物种多样性与植被透光率呈线性正相关（P 0.05）；地上生产力与土壤NO3—- N含量呈线性正相关（P 0.05）；随着施氮量的增加物种丰富度与生产力之间呈负相关关系。

The results showed that the species richness,the speciesdiversity and its biomass of understorey vegetation decreased with the stand age in-creasing.There was the most significant negative-linear relationship between thiskind of changes and age.It is possible that the certain shading condition may benefit to understorey growing better.The richness,diversity index and biomass of thevegetation in eucalypt plantation decreased with CPR increasing,however,after ro-tating by watermelon one rotation,the richness,the diversity index and biomass ofunderstorey in CP stand increased,this result will provide the possibility of therestoration and reestablishment of vegetation in eucalypt plantations.The nutrientstorage of understorey decreased in accord with the productivity decreased withCPR increasing,this is the result which the stand enviroment became worse and thestand stratum competed with the vegetation for the water and fertility of soil.

结果表明，随着年龄的增长，桉树林下植被物种丰富度降低，多样性减少，生物量下降，这种变化趋势与年龄存在极显著的负线性关系；随着造林密度的增加物种丰富度降低，多样性也下降，但林下植被生物量尚有增加，可能是一定程度的庇荫有利于桉树林下植被的生长；随连栽代次的增加，桉树林下植被丰富度降低，多样性指数下降，生物量减少；但在轮作一茬西瓜后的林地，物种丰富度提高，多样性指数升高，生物量增加，为桉树林下植被的恢复与重建提供了可能性；随连栽代次增加，林下植被养分总量逐代下降，与生产力下降一致，这是林分环境恶化后上层乔木和林下植被对水肥竞争的结果。

richness：丰度

二、运用物种的丰度(richness)、歧异度(diversity)、或均匀度(evenness)的指标:物种丰度的调查采样,仍属「存在与否」类别的资讯,对反应整体群聚的代表性不足,且与样本数及采样点选择息息相关.

richness：丰富

指超越感官刺激的共鸣与感染力,是一些细致的感觉,亦或是不同感觉间的复杂交互作用,所造成的心理感动,其他常用的语汇还有芳香(aroma)、丰富(richness)、风味(flavor)、特色(varietal distinction or character)等等,

richness：丰[富]度

人们通常认为是媒介的交互性(interactivity)和丰富度(richness)产生了这种临场感(Klein 2001;Steuer 1992). 然而,在研究三维广告时,我们却发现媒介的交互性和丰富度并不能充分解释消费者体验模拟产品时的心理活动. 因此,

richness：丰富性

这一学派强调与自然的协调、和平交往、男女平等、考虑全球利益的有机相互依存等等,并创造性地运用了混饨学、过程哲学等思潮,提出了与"泰勒原理"相对的"4R"为标准的后现代课程设计理念,即"丰富性"(Richness)、"回归性"(Recursion)、"关联性"(Relations)和"严密性&qu
