摘　　要：由华南区15、42个测站构成了相互独立的低、高密度两种站网。用1958—2000年5—6月逐日降水资料,分析了两种站网华南前汛期降水量场特征的异同。统计表明:1)两种站网给出的华南区域平均季、月降水量无显著差异,候、日降水量有显著差异;2)两种站网给出的逐日气候及其异常场均存在显著差异。Two independent station networks are selected in South China. The low-density one includes 15 stations, while the high-density one contains 42 stations. The similarities and differences of precipitation fields of the pre-flood season of South China obtained from the two networks are analyzed based on their May-June daily precipitation data from 1958 to 2000. Statistical results show that：1）the regionally averaged precipitation of the seasonal and monthly scales obtained from the two networks has no notable difference, but one of pentadly and daily scales has ; 2） both the daily climatological mean and anomaly fields obtained from the two station networks have notable differences.
