摘  要:
通过将一组原始调查数据使用4种数据处理方式,分别对5个常用均匀度指数进行计算。结果显示,Sheldon指数受物种数量的影响更大,而其他指数则是更多地受物种个体数量的影响。而不同数据处理方式也存在侧重点,适用于不同情况。

摘  要:
By using four data treatment models on the original investigation data,it was calculated the five common evenness indexes respectively.The results show that the Sheldon index has the more impact by the species quantities,while the other indexes are affected more by the species individual quantities.Different data treatment models also have different emphasis points that are applicable to the different situations.
