摘　　要：在环境空气监测点位优化中，为反映优化后点位的整体代表性，需要在允许的测定误差内以最少的测点反映区域内较长时期的整体 污染水平、污染分布状况和污染趋势。本文以博山城区为例，利用地理变异系数法和 Fisher 最优分割法对所布设点位进行数理统计。该方法 使用简便，分级自然，避免了诸多人为因素的影响，同时，优选结果具有较强的整体代表性。While monitoring the position and optimizing in the surrounding air, the whole repoesentativeness of the position after optimize in order to reflect, need it with examining some the whole level of pollution of longer period , pollution distribution state while reflecting the area and polluting the trend at least in the survey error of allowing. This text takes urban area of Boshan as an example, utilize the law of geographical coefficient of variation and Fisher optimum split method to carry on mathematical statistics to the position laid. This method is used simply and conveniently, grade it naturally , has avoided the influence of a great deal of human factors , meanwhile, the optimum seeking result has stronger whole representativeness.
