利用三维荧光光谱法（3D-EEM ）研究了保定府河溶解性有机质（DOM ）的荧光特性，根据三维荧光光谱图中荧光峰的位置、数量及强度变化，荧光峰之间的相关性，初步判断荧光物质的类别、分布和来源。府河水体溶解性有机质主要有类蛋白质和类溶解性微生物代谢产物两类，类蛋白荧光峰 Ex/Em＝225～230/340 nm（A）；类溶解性微生物代谢产物荧光峰Ex/Em＝275/340～350 nm（B）。不同采样时间和采样点，府河水体基本上都存在类蛋白荧光峰和类溶解性微生物代谢产物荧光峰。分析各荧光峰强度与水质指标相关性发现，两荧光峰之间呈显著性相关，表明研究区域中类蛋白质和类溶解性微生物代谢产物具有同源性；DOM两类荧光峰与COD ，T N ，T P ，N H3-N呈显著正相关，表明通过两类荧光峰强度可推测府河污染程度，为府河污染防治和沿河流域生态环境治理提供参考。

The fluorescence properties of dissolved organic matter (DOM ) in Fu River in Baoding were investi-gated by three-dimensional fluorescence spectrometry .The type ,distribution and origin of the DOM were esti-mated on basis of the position ,number and intensity of fluorescence peaks in the spectra .Two types of fluo-rescence peaks were detected from Fu River .There are protein-like fluorescence peaks A with Ex/Em=225~230/340 nm and soluble microbial metabolites peaks B with Ex/Em=275/340~350 nm .The protein-like fluo-rescence peaks and soluble microbial metabolites peaks were founded in different times and stations in Fu Riv-er .Certain correlation was observed between the fluorescence intensity of DOM and the water quality parame-ters of Fu River .Good correlation of different fluorescence peaks showed the same of source .The fluorescence intensity of the two types had a significant positive relationship with COD ,TN ,TP and NH3-N concentration , this phenomenon indicating that the fluorescence peaks can speculate the level of pollution of Fu River .These results provided a reference for the pollution control in Fu River .
