| 摘 要： | 在多点源影响条件下,结合河流水质空间变化规律,根据地质统计学中构造变量空间统计结构的方法,利用迭加原理,建立点污染源对河流水质影响的评价方法。在该方法中,水流断面流速不作为参变量出现。实例研究表明,在流速实际测验精度不能满足经典水质模型的条件下,该方法可取得令人满意的效果。

| Abstract: | Based on the spatial distribution rule of water quality in rivers, a method to evaluate the influence of multi point sources on river water quality was established using geostatistical method for constructing spatial statistic structure of variables and superposition principle. The velocity of cross section is not listed as a parameter in the model. Case studies show that the result of the model is satisfactory even though the accuracy of the measured velocity cannot meet the requirement of classic water quality models. |
