利用中国524个站的高质量降水资料，分析了1961 - 2008年中国不同气候区主汛期（5 - 9月）降水量的变化趋势。但在我国不同地区表现出不同的特点。在大多数温带季风区（中国东北），雨季总降水量和降水日数呈减少趋势;但该区域大多数站点的降水强度呈上升趋势。结果表明，中国东北地区雨季降水量减少主要与降水日数减少和干旱化有关，从而影响了温带季风区的水资源利用。在大多数亚热带和热带季风气候区（中国东南部），雨季降水量和降水日数（11-50，>50毫米）呈略正趋势。然而，降水日数与
Using high-quality precipitation data from 524 stations, the trends of a set of precipitation variables during the main rain season (May-September) from 1961 to 2008 for different climate regions in China were analysed. However, different characteristics were displayed in different regions of China. In most temperate monsoon regions (north-eastern China), total rain-season precipitation and precipitation days showed decreasing trends; positive tendencies in precipitation intensity were, however, noted for most stations in this region. It is suggested that the decrease in rain-season precipitation is mainly related to there being fewer rain days and a change towards drier conditions in north-eastern China, and as a result, the available water resources have been negatively affected in the temperate monsoon regions. In most subtropical and tropical monsoon climate regions (south-eastern China), the rain-season precipitation and precipitation days (11-50, with >50 mm) showed slightly positive trends. However, precipitation days with
