| 摘要: |
| 选择分布在不同流域的15个与自动监测站位置一致性较好的断面，对其进行为期1年的“同时同点位”对比监测。分析数据发现：由于采样时间和位置的偏差，自动监测月均值与常规手工监测数据的可比性并不理想。采用以下4种方法评价水质：自动5项、手动5项、手动21项、自动5项+手动16项。比较第1和第2种方法，水质评价类别相同与变化一类（发生一个水质类别变化）的占比之和在85%左右；比较第1和第3种方法，类别相同与变化一类的占比之和在80%左右；比较第3和第4种方法，类别相同与变化一类的占比之和接近90%，因此该组合是更合理的地表水水质评价方法。 |

| Abstract: |
| 15 conventional monitoring sections, which were located in the same location with automatic monitoring stations, distributed in different river basins, were selected to compare the data obtained by both manual monitoring and automatic monitoring. The results showed that the monthly mean values of automatic monitoring were not comparable to the data of manual monitoring due to the deviation of sampling time and sampling location. In terms of water quality evaluation, at least 4 methods were available: evaluated by 5 parameters obtained from automatic monitoring, evaluated by 5 parameters obtained from manual monitoring, evaluated by 21 parameters obtained from manual monitoring, and evaluated by the integrated 5 automatic parameters and 16 manual parameters. Compared with method one and method two, the sum of same class and one class varied accounted for about 85%, compared with method one and method three, it accounted for about 80%, and compared with method three and method four, it accounted for about 90%.Therefore,this is a more reasonable method of surface water quality evaluation. |
