| 1. | Rarity is not merely determined by the number of individuals in a species , it is also about how unusual that species is
稀缺性不仅仅由某个物种所包含的个体数量决定，还和物种的数量有关。 |
| 2. | Thus , when the population is small multiplication is slow , but as the population gets larger , the rate of multiplication also increases
因此，个体数量基数小时，增长慢，而数量越大时，增长数量也越快。 |
| 3. | The changes of spider community structure in transitional zone has important effect on the changes in cotton field
荒漠过渡带蜘蛛群落的物种数、个体数量、多样性、均匀度、稳定性都高于棉田蜘蛛群落的对应特征。 |
| 4. | Exponential growth a type of growth in which the rate of increase in numbers at a given time is proportional to the number of individuals present
指数生长：指定时间内，增长速率与个体数量的增长呈一定比例的生长类型。 |
| 5. | A total of 445 species belonging to 24 families was collected , among which noctuidae and geometridae are dominant groups and 13 species are common to every forest zone
随海拔的升高类蛾的多样性指数明显降低，其中红松阔叶林带蛾类的物种丰富度、个体数量和多样性指数都最高。 |
| 6. | Number of species and individuals , species diversity index and evenness , and proportion of wader birds decreased from bay - mouth to bay - head , and was lowest in midbay
其中湾口的水鸟物种数、个体数量、多样性指数、均匀度指数以及涉禽所占比例均为最高，湾底次之，湾中部最低。 |
| 7. | Although the species is widely distributed in tropical and subtropical regions , it has a special habitat requirement and in recent years its distribution area and population size are decreasing
本种分布虽广，但其生长环境很特殊，目前在世界各分布区的范围正不断缩小，个体数量亦日趋减少。 |
| 8. | The individual number of terrestrial mollusca is continuously reducing with the rise of altitudes in mangshan nature reserve , but it sems no apparent change in babaoshan area
莽山自然保护区陆生贝类的个体数量随着海拔高度的增加而减少，八宝山陆生贝类的个体数量随海拔高度的变化表现不出明显的变化规律。 |
| 9. | Thus with citing these results we separatedly and thoroughly examined all possible dynamical manners of the changing of the ; populations when the species were developing under the function of catching efforts in three different areas departed by the size relation between the intrisic rates of the system and the values of the harvesting efforts . so we could give out - righter qualitative analysis to this system and the scope of catching efforts which make the species sustainable and the asymptotical properties of the corresponding system were also clear
于是，本文在引用已有结论的基础上，根据给定捕获努力量与系统内禀增长率之间的大小关系分三部分考虑了在不同的捕获努力量作用之下，种群发展过程中其个体数量变化可能出现的全部动力学行为，从而对系统给予了较完整全面的定性分析，求出了使生态系统持续发展的捕获努力量的范围及相应的系统的渐近性质 |
