内蒙古中西部地区城市硬化地面雨水高效利用研究

针对内蒙古师范大学盛乐校区水资源紧张、水费高的突出问题,提出采用硬化地面为集雨面、利用蓄水池储存的方法进行雨水的收集、储存与利用。结果表明,盛乐校区全年降雨量主要集中在5、6、7、8月;蒸发量除了1和12月之外,其他月份的蒸发量均较大;硬化地面有效降水量应大于4 mm;硬化地面全年平均可收集雨水为0.31 m3/m2,其中8月份最大,收集雨水约0.17 m3/m2。

Study on Rainwater Collection Efficient of the City Hardened Ground in the Central and Western Region of Inner Mongolia

In order to solve the problems of water shortage and high water price in Shengle Campus of Inner Mongolia Normal University,it was proposed that,with the hardened ground as the rainwater harvesting surface and by adopting the method of reservoir storage,the rainwater could be collected,storied and utilized.Results indicated that,the precipitation of Shengle Campus mainly concentrated in May,June,July and August;strong evaporation could be seen in the rest months except in January and December;the effective precipitation in the hardened ground was above 4mm;while the annual average rainwater to be collected is 0.31 m3/m2,especially in August with the maximum rainwater collection of 0.17 m3/m2.
