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。

Shannon-Weiner index、 Simpson index and Species evenness index were 2.13, 0.85 and 0.81 of frigid grassland, which were 1.36, 0.65 and 0.65 of upland brushy grassland.

高寒草原Shannon-Weiner指数、Simpson多样性指数和均匀度指数分别为2.13、0.85和0.81，山地灌丛草原则最低只有1.36、0.65和0.65。

A total of 10 species of Chiroptera, belonging to 4 families and 6 genera, were recorded in the area, which takes 32.3% of the 31 Chiroptera species in whole Hainan Island. The Shannon-Weiner index is 2.734, Index of evenness is 0.823, and Simpson index is 0.817. The fauna characteristics was analyzed.

结果显示，马鞍岭火山口地区共有翼手目动物10种，隶属4科7属，占海南岛已知翼手目种类（31种）的32.3%，具有较高的翼手目物种多样性，其香农－维纳指数为2.734、均匀性指数为0.823、辛普森指数为0.817。

For A-early F type MS stars, stellar chromospheric activity decrease with stellar rotation period, but increase with Rossby number; For M type MS stars, stellar chromospheric activity increase with stellar rotation period and Rossby number, and stellar chromospheric activity reach saturation at large color index; For the MS stars between mid-F to M type, stellar chromospheric activity decrease with stellar rotation period and Rossby number.

在第五章中，我们采用不同的磁活动指数研究了晚型恒星磁活动与恒星自转参量(自转周期、Rossby数)、磁活动与恒星色指数以及恒星磁活动指数之间的相关性。大样本分析显示晚型主序恒星的色球活动与恒星自转参量的研究晚型主序恒星的色球活动与恒星自转参量间的关系表现出对恒星光谱型的依赖。

Responses of different genera of collembola to the heavy metal pollution are different. The Sinella is insensitive to Cu pollution, while Onychiurus and Isotomurus are sensitive to Cu pollution.

研究结果表明，种类数和均匀度指数都与CU的污染浓度（包括全铜含量、刊值、有效铜含量）之间的相关性达到显著或极显著水平，多样性指数与CU污染指数之间相关系数R为 A.892＊，达到了显著水平。

The least is in the meadow.The diversity index of soil collembolan is closely correlated with the group number and individual number.

土壤虫的多样性指数与类群数和个体数密切相关，多样性指数与均匀度指数基本成正相关。

In this paper,studied on the soil collembolan in the Liangshui National Natural Conserve.Adopt diversity index,evenness index and common index to analyze.In the 10 habitats,the number of soil collembolan in the manmade Korean pine forest is the most.

对凉水国家自然保护区土壤虫的生态分布进行了研究，采用多样性指数、均匀度指数、共同性指数进行了分析。10个生境中土壤虫数量最多的是人工红松林，最少的是草甸。

With a study of plant community succession on 5 stocking rates,herbage utilizational efficiency and risk-benefit balance,it is suggested the sustainable development should follow:(1)no degradational principle of rangeland,(2)the maximum herbage utilizational efficiency,(3)the risk-benefit balance,When stocking rate was no more than 2.67 sheep/hm2,the proportion of grasses and plant biodiversity index and evenness were increased based on Artemisia frigida and short-grass rangeland.

草地畜牧业可持续发展的三大生物经济原则为草场不退化原则、最大生物学效率原则和风险-利润权衡原则：(1)草场不退化原则。在冷蒿小禾草退化草原上，暖季期间1.33～2.67羊/hm\+2的放牧率下可使其发生恢复演替，禾草的比例增大，植物多样性指数和均匀度指数均有所提高，从而达到利用式改良的目的；相反，若继续重牧或过牧，放牧绵羊喜食的植物种类将进一步减少，植物多样性指数也有所降低。
