中文摘要:
      应用径流系数法分析了杨凌示范区城区雨水资源利用潜力。2007年可直接收集利用的雨水总量为123.91万m3,占该年杨凌城区总用水量的28.3%;可处理后回用的雨水总量为367.15万m3,但目前仅有占城区总面积1.98%的绿地利用雨水12.93万m3,其它均未予利用;预计到2020年,以枯水年计算,可直接收集利用的雨水总量为3 233.03万m3;可处理后回用的雨水潜力巨大。并进一步对杨凌城区实施雨水利用后可能产生的经济、社会和生态效益进行了评价分析。
英文摘要:
      Runoff coefficient method is used to analyze the potential amount of rainwater utilization in Yangling Agricultural Hi-tech Industries Demonstration Zone, and the results indicate that the total amount of recuperated rainwater from the urban area in 2007 is 1 239 100 m3, accounting for 28.3% of the zone's total water consumption.The total amount of runoff yield and possible water use is 3 671 500 m3, but only 129 300 m3 is now used for green land irrigation.It is predicted that by the year of 2020 year, the total amount of directly harvested rainwater is 32 330 300 m3, showing a huge potential of rainwater utilization.Evaluation and analysis is also made of the possible economic and social benefits resulted from rainwater utilization.
