The dilemma which remained unsolved using Rao-Stirling diversity, namely of how variety and balance can be combined into "dual concept diversity" (Stirling in SPRU electronic working paper series no. 28. http://www.sussex.ac.uk/Units/spru/publications/imprint/sewps/sewp28/sewp28.pdf, 1998, p. 48f.) can be clarified by using Nijssen et al.'s (Coenoses 13(1):33-38 1998) argument that the Gini coefficient is a perfect indicator of balance. However, the Gini coefficient is not an indicator of variety; this latter term can be operationalized independently as relative variety. The three components of diversity-variety, balance, and disparity-can thus be clearly distinguished and independently operationalized as measures varying between zero and one. The new diversity indicator ranges with more resolving power in the empirical case.
使用饶 - 斯特林多样性仍未解决的困境，即如何将多样性和平衡性结合成“双重概念多样性”（斯特林，《SPRU电子工作论文系列》第28号。http://www.sussex.ac.uk/Units/spru/publications/imprint/sewps/sewp28/sewp28.pdf，1998年，第48页及以后），可以通过采用奈伊森等人（《群落》13(1):33 - 38，1998年）的观点来阐明，即基尼系数是平衡性的完美指标。然而，基尼系数不是多样性的指标；后一个术语可以独立地作为相对多样性来操作化。因此，多样性的三个组成部分——多样性、平衡性和差异度——可以清晰地区分，并作为在0到1之间变化的度量独立地进行操作化。在实证案例中，新的多样性指标具有更高的分辨能力。
