门头沟区泉水资源生态产品价值核算

Ecological product value accounting of spring water resources of Mentougou District in Beijing

北京市门头沟区泉水资源优势突出,在首都供水及生态系统中处于重要地位。研判北京市门头沟区实施“百泉复涌”后泉水资源的实际情况,采用市场价值、代替成本、旅行费用等方法,围绕物质产品服务、调节服务、文化服务等三大类7项生态系统服务功能,对门头沟区范围内的泉眼进行生态产品价值初步核算(GEP)。结果表明,“百泉复涌”实施将新增泉水资源GEP总值为34.87亿元/年,水源涵养功能发挥巨大生态价值,将为促进门头沟区经济社会与生态环境保护协调发展以及生态产品价值转化提供技术支撑,践行“两山”理论。

The unique advantages of spring water resources of Mentougou District in Beijing play an important role in the water supply and ecological system of the capital.To study and judge the actual situation of spring resources after the“Hundreds of Springs Resurgence”in Mentougou District,,adopt the methods of market value,substitution cost,travel expense,etc.,and focus on 3 categories of 7 ecosystem service functions,including material product services,regulatory services,and cultural services,to conduct preliminary accounting of gross ecosystem product(GEP)for springs in the whole Mentougou District.The results show that the total value of GEP for newly added spring water resources in the whole district will be 3.487 billion yuan/year,and the water conservation function plays a huge ecological value.It will provide technical support for promoting the coordinated development of economic society and ecological environmental protection and the value transformation of ecological products in Mentougou District and practice the“two mountains”theory.
