摘　　要：针对常规定点水质监测方法无法完整再现水质指标的时空连续分布特征的问题,将船只搭载的水质实时监测设备与GPS同步形成基于GIS数据支撑的走航在线水质监测手段。通过与常规水质监测方法的对比,走航在线水质监测结果的可靠性得到了验证。在温瑞塘河河网选择部分河段进行的实地研究结果表明,走航在线水质监测能够较好地实现对较小尺度范围内水质指标空间分布细节的描绘及对分散点源污染的监测,是对常规定点水质监测的有益补充。Routine monitoring at fixed sites can not represent temporal and spatial water quality patterns of a river system thoroughly.An integration of GIS data and on-board real-time water quality monitoring might be useful to obtain detailed information of water pollution continuously.The water quality measurement results of standard method and real-time monitoring method were highly correlated in our study,so that validating the reliability of on-board monitoring.In situ investigation in a division of Wen-Rui Tang river network showed remarkable resolution of water quality characteristics has been described by on-board real-time water quality monitoring,so that facilitating monitor on dispersed point pollution sources.The integration of GIS data and on-board real-time water quality monitoring can be compensation to fixed sites routine monitoring.
