山东省当地水资源来源于大气降水,1956～1995年40年系列,全省多年平均降雨量为684.3mm,径流量为22.7亿m~3,20％、50％、75％、95％不同保证率径流量分别是323.5亿、203.4亿、132.2亿和63.4亿m~3。50％、75％、95％不同保证率地表水资源可利用量分别是83.88亿、63.83亿和22.08亿m~3。根据40年实测资料分析计算,全省多年平均地下水资源量为153.50亿m~3,可开采量为125.93亿m~3。扣除地表水资源与地下水资源相互转化的重复计算量, The local water resources in Shandong Province are derived from the atmospheric precipitation and the series from 1956 to 1995 were 40 years. The average annual rainfall in the province is 684.3mm and the runoff is 2.27 billion m 3, 20%, 50%, 75% and 95% respectively The rate of surface water resources utilization is 32.38 billion yuan, 6.383 billion yuan and 2.208 billion yuan respectively, with flow rates of 32.35 billion yuan, 20.34 billion yuan, 13.22 billion yuan, and 6.34 billion yuan to 3.50%, 75% and 95% respectively . According to 40 years of measured data analysis and calculation, the province’s average annual groundwater resources amount to 15.35 billion m ~ 3, recoverable amount of 125.93 million m ~ 3. Deducting the surface water and groundwater resources, mutual conversion of the calculation,
