摘要:
[目的] 对重要饮用水源地密云水库水生态服务功能的动态变化及其受南水北调工程的影响进行分析,为该水库生态系统平衡和水资源保护提供依据。[方法] 运用市场价值法、替代工程法、替代成本法、碳交易法、支付意愿法、比例折算法和成果参照法,定量研究密云水库水资源供给,提供水产品,调蓄洪水,增加湿度,夏季降温,净化水质,涵养水源,固定CO2,释放O2,保护生物多样性,旅游休闲和科研教育等生态服务价值的变化情况。[结果] 2008—2019年密云水库水生态服务价值介于709.96~1 003.60亿元之间,呈先小幅波动后增大的趋势,其中,支持服务价值(尤其是保护生物多样性)占主导地位(64%~80%);调节服务价值处于次要地位(18%~33%),主要表现为涵养水源、增加湿度、夏季降温和调蓄洪水;供给服务价值和文化服务价值合计比例不足5%。南水北调工程使密云水库的增加湿度价值、夏季降温价值、涵养水源价值、净化水质价值、旅游休闲价值、科研教育价值和水生态服务总价值极显著提升(p<0.01),调蓄洪水价值极显著下降(p<0.01)。[结论] 密云水库水生态服务功能除了取决于气候等自然因素外,还受南水北调工程、交通便利程度等人为因素的影响。建议加强密云水库水量水质监测和文化生态潜能开发,以保障北京市饮用水储备安全可靠。

Abstract:
[Objective] The dynamics of water-related ecosystem services and its influences by south-to-north water diversion project were analyzed, in order to protect water resources and ecosystem balance of Miyun Reservoir. [Methods] The methods of market value, alternating engineering, alternative cost, carbon trading, willingness to pay, proportion apportionment and benefit transfer were used to evaluate the water-related ecosystem services of water resources supply, aquatic product provision, flood regulation and reservation, air humidity improvement, summer heat amelioration, water purification, water conservation, CO2 sequestration, O2 release, biodiversity protection, tourism and leisure and scientific research and education of Miyun Reservoir. [Results] The water-related ecosystem service values of Miyun Reservoir ranged from 70.996 to 100.360 billion during 2008—2019, which fluctuated slightly at first and then increased. As for components of water-related ecosystem services, the value of supporting services, especially biodiversity protection, played a dominant role (64%~80%). The value of regulating services was in the secondary position (18%~33%), which was mainly manifested in water conservation, humidity improvement, summer heat amelioration and flood regulation and reservation. The value of provisioning services and cultural services together accounted for less than 5%. Moreover, the south-to-north water diversion project significantly increased the values of air humidity improvement, summer heat amelioration, water conservation, water purification, tourism and leisure, scientific research and education and total ecosystem services (p<0.01), while significantly decreased the value of flood regulation and reservation (p<0.01). [Conclusion] The water ecological service function of Miyun Reservoir is affected not only by natural factors such as climate, but also by human factors such as south to north water diversion project and traffic convenience. The monitoring of water volume and quality and the development of cultural and ecological potential of Miyun Reservoir should be strengthened, so as to guarantee the security and reliability of drinking water reserves for Beijing City.
