| 摘 要： | 补贴措施是政府推广雨水利用的一种重要手段,合理地定量计算补贴金额是一项具有重要现实意义的工作.通过示范区雨水集蓄利用现场试验,观测不同降雨条件下集雨桶的储水量及特征气候条件下停车场的洗车需水量;并以该工程为例,对城市雨水集蓄利用的成本-综合效益进行评价.结果表明：城市雨水利用工程综合效益体现在生态、社会效益上,净收益率较低,需要政府扶持和激励.本项目10年的投资净收益率平均为7.05％,扣除物价上涨率4％,实际收益率仅约为3％,低于一般水利工程项目的收益率.结合大连市经济社会发展状况,提出根据可定量计算的生态效益进行现金补助的雨水利用激励措施,相对其他措施,这种补贴方法更加透明、合理.

| Abstract: | To quantitatively calculate the amount of subsidy is very important for the government, since cash incentive is an effective method to promote rainwater collection. In this study, we investigated the volume of collected water from the roof in different rainfall conditions and the amount of consumed water to wash cars in the representative climatic situations through field tests. Then we assessed the cost and benefit of the project. The calculation results show that the project could offer such a low net income ratio as to be encouraged and supported by the government although the ecological and social benefit was obvious. The average net benefit rate in 10 years was lower than those of other water conservancy projects, for it was only 7.05 % , and was so far as to 3% as the inflation rate 4% was subtracted. Combining with socio-economie development status in Dalian, this paper also presents several incentive measures, in which the amount of cash subsidy is counted according to the quantitatively calculated eeo- benefit. Compared to other means, the method mentioned above is more reasonable. |
