摘　　要：水质监测结果是水质评价与水污染防治的重要依据。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数据支撑的连续纵向水质监测方法。重点对水质监测仪及GPS空间数据集成问题进行了分析讨论,并在温瑞塘河流域进行了实验论证。结果表明,连续性纵向水质监测不但能进行连续时空水质监测,还能与GPS、GIS结合进行连续性时空分布特征的分析。Water quality monitoring results are the basis for evaluating water quality impairments and controlling water contamination. Routine monitoring at fixed sites cannot fully represent temporal and spatial water quality patterns in many river systems. An integration of GPS data and real-time water quality monitoring while traveling in a boat presents a means to collect continuous longitudinal water quality data that can be subsequently analyzed using GIS. The paper examines changes in water quality using a water quality sonde coupled with GPS location data in the Wenruitang River. The results indicate that continuous longitudinal water quality monitoring not only can monitor fast-changing and continuous water quality, but can also be combined with GPS for GIS analysis.
