| 摘 要： | 本文是Ｊｅｎｋｓ和Ｃａｓｐａｌｌ工作的基础上，提出了一个量度分级总体精度的统计量，它不仅可以反映各个等级内部数值的紧密程度，而且可以反映各个等级之间的相差程度。这为专题要素的合理分级提供了一种更为客观可靠的方法。

| Abstract: | bstract:On the basis of Jenks and Caspall's research statistic has been put forward as a measure for total classifying precision. It can reflect not only the close degree of internal values within a grade, but also the disparity between diffe rent grades. Thus a more objective and reliable method has been provide for grading of thematic elements. |
