中文摘要	随着技术的进步与发展,国内外学者早已利用不同的技术手段对水质指标的评价与估算开展了大量研究,但是利用二维荧光峰值估算水质指标的方法尚不多见.以艾比湖流域地表水为研究对象,利用多元统计分析和逐步回归分析方法,对二维荧光峰值和水质指标建立估算模型以初步探究二者的相互关系.结果表明:(1)艾比湖流域不同河流的水质状况不同,博尔塔拉河(简称博河)的TN含量最高,水库及水渠的TP含量最高.(2)同一水样点有三个荧光峰(Peak1, Peak2和Peak3)且强度逐渐减弱,不同河流的荧光峰强度不同,其中博河、水库及水渠的荧光峰强度变幅最大.(3)经过荧光峰值与水质指标的相关分析发现Peak1与BOD_5,Peak2与BOD_5, Peak2与COD,Peak2与DO具有较好的相关性,相关系数分别为:0.479,0.371,0.655和0.618.将单荧光峰值和水质指标建立估算模型,经验证四组估算模型的精度较差,单峰值建模无法达到监测要求.因此,在单荧光峰值建模的基础上,将每个水样的三组荧光峰值和水质指标进行综合建模,建立多元回归方程,经模型验证得出三组荧光峰值与DO的综合模型效果最好,R=0.756, RMSE=1.001.因此二维荧光峰值与水质指标DO的综合估算模型是可行的,对干旱区水质指标监测具有一定的参考意义,为艾比湖流域水资源的开发、利用及保护提供科学依据.
英文摘要	With the progress and development of technology,domestic and foreign scholars have already made a lot of researches on the evaluation and estimation of water quality indexes by different technical means. However,the method of estimating water quality by using two-dimensional fluorescence peak value is still rare. The paper took the surface water of Ebinur Lake basin as the research object,using multivariate statistical analysis and stepwise regression analysis method,and explored the interrelationship of two-dimensional fluorescence peak value and water quality indexes by establishing an estimation model. The results showed that: (1)The water quality was different for the different river of Ebinur Lake basin,the total nitrogen(TN) content of Bortala River was the highest,and the total phosphorus (TP) content of reservoir and canal were the highest. (2) The same water sample has three fluorescence peaks (Peak1,Peak2,Peak3),and the fluorescence peak intensity gradually weakened. The intensity of two-dimensional fluorescence peak value in different rivers was different,among them,the variation range of fluorescence intensity in Bortala River,reservoir and canal were the highest. (3)The correlation analysis between two-dimensional fluorescence peak value and water quality indexes showed that Peak1 and five days biochemical oxygen demand(BOD_5),Peak2 and BOD_5,Peak2 and chemical oxygen demand (COD),Peak2 and dissolved oxygen(DO) both had good correlation,and the correlation coefficient was 0.479,0.371,0.655 and 0.618 respectively. The estimation model was established by the single fluorescence peak value and water quality indexes,which could not meet the monitoring requirements,because the poor accuracy of the four models were verified. Therefore,based on the single fluorescence peak value model,we established a integrated model of the three peaks and water quality indexes of each water sample for obtaining multiple regression equation. We found that the integrated model of the three groups of fluorescence peak and DO had the best effect through the model validation,the Correlation Coefficient was 0.756,and the Root Mean Square Error was 1.001. Therefore,the synthetic estimation model of two-dimensional fluorescence peak value and water quality indexes is feasible,which has a certain reference for the monitoring of water quality in arid area,and provides scientific basis for the development,utilization and protection of water resources in the Ebinur Lake basin.
