我省现有委托雨量站368个（其中自记187个），比全省水文气象站降水总数还多一倍。这是准确计算水资源不可替代的重要依据，也是记录气候变化具有永久意义的珍贵资料。八十年代以前这部分资料的精度质量基本没有问题，九十年代以来在经济效益的冲击下，一部分资料动摇下滑。因 There are currently 368 rainfall stations (187 self-recorded) in our province, more than double the total rainfall of hydrometeorological stations across the province. This is an important basis for accurately calculating the irreplaceable use of water resources and is also a valuable resource for documenting the permanent significance of climate change. Before the 1980s, the accuracy and quality of this part of the data were basically free of problems. Since the 1990s, part of the data has been swayed by the economic impact. because
