白永年,现任山东省水利厅副厅长。1987年被授予“国家级有突出贡献的中青年专家”称号。做为科学家,他富有自信心。1963年在山东省水利科学研究所曹县除涝试验站工作期间,他就在大量调查分析中发现了发生旱、涝、碱灾都与地下水有关。经测试证明,地下水位下降1米,可蓄藏60毫米左右的降雨;地下水位下降5米,可蓄藏300毫米的涝水。如果把地下水位控制在2米以下,就可以有效地防止次生盐碱的发生。根据这一认识,他和他的同事们提出了以 Bai Yongnian, the current deputy director of Shandong Provincial Department of Water Resources. In 1987 was awarded the “national outstanding contributions of young and middle-aged expert” title. He is full of confidence as a scientist. In 1963 in Shandong Province Institute of Water Conservancy Institute of Caoxian waterlogging test station during his work in a large number of investigations found that the occurrence of drought, waterlogging, and alkali are associated with groundwater. The test proved that the groundwater level dropped 1 meter, about 60 millimeters of precipitation can be stored; groundwater level dropped 5 meters, can store 300 mm of waterlogging. If the groundwater level control in 2 meters below, you can effectively prevent the occurrence of secondary salt. Based on this understanding, he and his colleagues proposed
