摘要 徐州市城市供水主要是地下水据计算,规划区917.86km^2范围内地下水可采资源总量为2.48×10~8m^3/a,其中大气降水入渗补给量约占70%,可见降水入渗补给量对地下水补给保证程度起决定性作用,亦是城市供水规划制订的重要参考依据。徐州市城市供水主要是地下水据计算,规划区917.86km^2范围内地下水可采资源总量为2.48×10~8m^3/a,其中大气降水入渗补给量约占70%,可见降水入渗补给量对地下水补给保证程度起决定性作用,亦是城市供水规划制订的重要参考依据。 Abstract: Groundwater is the main source of water supply in Xuzhou City. The total resources of workable groundwater is 2. 48 x108 m3/a, of which the infiltration recharge amount of precipitation occupies 70 per cent. The regression analysis and Fouries series are firstly used to calculate the precipitation in the area and to reveal the cyclic change regularity of precipitation. The change model of meteoric water has been set up and the precipitation has also been measured in the area. Thus , the analysis of the recharge amount of groundwater within the year of 2000 in the area shows that though the infiltration amount of precipitation will be smaller than present state by the end of 20th century, the water shortage can be compensated by an increase of lateral seepage and irrigation return flow amount of avaiable surface water. The recharge of groundwater in Xuzhou area can be compensated around the year of 2000.
