[目的
]
对城市海绵小区雨水利用措施的经济、环境及社会效益进行识别计算并与其成本进行对比分析,为海绵小区建设评估提供参考。[方法
]
以第二批试点宁夏回族自治区固原市西南新区6个海绵小区为研究对象,采用水量平衡法、替代工程法、影子工程法、市场价值法、碳税法、造林成本法等,对海绵小区产生的雨水资源利用、固碳释氧、降噪、调蓄径流、文化教育等3大类共10项效益进行定量计算并采用效益费用比进行静态和动态成本效益分析。[结果
]
固原市西南新区6个海绵小区的总效益为2.91×10
5
元/a,其中雨水花园的效益为1.03×10
5
元/a,下沉式绿地的效益为7.99×10
4
元/a,植草沟的效益为6.15×10
4
元/a,经济、环境和社会效益比例分别为22.84%,76.89%和0.27%。[结论
]
海绵小区雨水利用有较好的投资效益,固原市海绵小区的建设产生了良好的经济、环境和社会效益,值得进一步研究推广。
[Objective] The economic
environmental
and social benefits of rainwater utilization at urban sponge community were evaluated and the cost comparative analysis were conducted in order to establish a reference for the evaluation of the construction of a sponge community.[Methods] The second batch of six sponge communities was obtained as the research object; this was sourced from the Southwest New District of Guyuan City in Ningxia Hui Autonomous Region. The water balance method
alternative engineering method
shadow engineering method
market value method
carbon tax method and afforestation cost method were used to generate the sponge community. The rainwater resource utilization
carbon sequestration
oxygen reduction
noise reduction
storage runoff
culture and education
etc
the ten benefits in three categories were quantitatively calculated. Further
the cost-benefit ratio was used for the static and dynamic cost-benefit analysis.[Results] The total benefit of the six sponge communities in the southwest of the New District of Guyuan City was 2.91×105 yuan/year. Moreover
the benefits of the rain garden
sinking green land
and planting grass were 1.03×105
7.99×104
and 6.15×104 yuan/year
respectively. The economic
environmental and social benefits accounted for 22.84%
76.89%
and 0.27%
respectively.[Conclusion] Therefore
the use of rainwater in the sponge community has noteworthy investment benefits. Accordingly
the construction of the sponge community in Guyuan City has produced good economic
environmental
and social benefits
which deserves further research and promotion.
