摘　　要：城市水源是一个城市的生命线,源水水质的变化直接影响城市供水的调度和运行管理。采用小波分析等方法对昆明市松华坝水源地的三个典型断面的营养盐时空变化特征进行了分析,结果表明,总氮、总磷浓度的空间变化不大,各断面变化趋势相近;总氮和总磷浓度年内变化具有明显的季节性,年际变化差异明显,具有准18个月左右的变化周期。研究结果可为供水厂的调度和运行管理提供依据。Urban water sources are the lifeline of a city, and changes of source water quality di- rectly affect scheduling and operation management of urban water supply. The methods of wavelet analysis were used to analyze the spatiotemporal changes of main nutrients at three different sections of Songhuaba water source in Kunming City. The main results show that spatial variation of total nitrogen and total phosphorus is not obvious, and the change range is similar at each section. The intra-annual variation of total nitrogen and total phosphorus shows remarkable seasonality, the inter-annual variation of total nitro- gen and total phosphorus is very obvious, and there is an 18 month quasi-periodic oscillation. The re- search results can provide basis for scheduling and operation management of water treatment plants.
