在机会集多样性评价中，基于机会项的空间分布状况建立评价模型是一类重要方法。与机会集多样性水平仅由机会项空间分布的范围大小决定的观点不同，提出了机会集多样性水平由机会项空间分布的范围大小和均匀状况共同决定。以机会项间距离的最大值代表机会项分布的范围大小，以机会项间距离序列的基尼系数代表机会项分布的均匀水平，并给出了基于两者构建的机会集多样性评价规则。
在機會集多樣性評價中，基于機會項的空間分佈狀況建立評價模型是一類重要方法。與機會集多樣性水平僅由機會項空間分佈的範圍大小決定的觀點不同，提齣瞭機會集多樣性水平由機會項空間分佈的範圍大小和均勻狀況共同決定。以機會項間距離的最大值代錶機會項分佈的範圍大小，以機會項間距離序列的基尼繫數代錶機會項分佈的均勻水平，併給齣瞭基于兩者構建的機會集多樣性評價規則。

Some diversity appraisal models of opportunity set are based on distribution of alternatives in the set. Different with views that diversity of opportunity set is determined only by rang size of the distribution, the article presented diversity of opportunity set is determined by range size and uniform condition of the distribution. The maximum distance between the alternatives represented the range of the distribution. The Gini coefficient of the distance series represented the uniform condition of the distribution. Two appraisal rules of diversity of opportunity set are presented based on the maximum distance and the Gini coefficient.
