常见的水质评价只反映污染强度，而忽略了污染历时及范围；概率法兼顾了这3方面的因素，评价结果更符合实际水质情况。应用概率法对邕江3个监测断面进行分析，认为水文站断面水质尚好，而豹子头及蒲庙断面的水质已有50%以上的污染机率，且污染历时长。

The common water quality evaluation method only reflects the pollution intensity and ignores pollution duration and range. Probability method takes account for the three factors and its evaluation results conform more to the practical water quality condition. The three sections' water quality of the Yongjiang river were analyzed by probability method, the results indicated that the water quality of hydrologic station section were better and the other two have 50% pollution frequency and pollution duration are longer.
