摘要
生态补偿对维护生态系统服务功能、促进区域绿色发展具有重大意义。本研究提出基于水资源格局和保险增益的区域横向生态补偿标准模型,用于解决研究区补偿方式单一、补偿效率低下的问题。以京津冀地区为例,分析研究区2000—2019年水足迹和水资源生态承载力情况,同时依据生态保护投入成本和分摊系数明确补偿主客体和水足迹补偿额;引入保险定价模型厘定生态保险费率,确定保险补偿额及生态补偿标准,测算了不同类型的生态系统服务价值。结果表明:2000—2019年,京津冀地区整体处于水生态赤字状态,农业水足迹占比高达94.5%;从补偿主客体来看,京津两地作为补偿主体,平均每年应分别向河北省支付水足迹补偿额4.02亿元和3.96亿元;河北省应获得保险费率为1.4%的生态保险金额2.28亿元,平均每年应获得京津两地支付生态补偿标准8.10亿元;水文调节为区域核心生态系统服务功能,多年平均价值为1879.74亿元。引入生态保险机制,对研究区构建横向生态补偿机制、完善生态系统服务功能以及提升生态系统服务价值具有重要的战略意义。
Ecological compensation plays an important role in maintaining ecosystem services and promoting regional green development.We built a regional horizontal ecological compensation model based on water resources pattern and insurance gain,and which was used to solve the problems of single compensation method and low compensation efficiency.Taking the Beijing-Tianjin-Hebei region as an example,we analyzed water footprint and water ecological carrying capacity from 2000 to 2019.The compensation subject and object and water footprint compensation amount were determined according to the input cost of ecological protection and allocation factor.Then,the insurance pricing model was introduced to determine ecological insurance premium rate.We calculated insurance compensation,ecological compensation standard and different types of ecosystem service value.Results showed that the whole region was at a state of water ecological deficit,with the agricultural water footprint accounting for 94.5%.From the perspective of the compensation subject and object,Beijing and Tianjin,as the compensation subject,needed to pay 0.402 billon yuan and 0.396 billion yuan(the amount of compensation)to Hebei Province each year.Hebei Province obtained a total of 0.228 billion yuan of ecological insurance with an insurance premium rate of 1.4%,and should receive an average annual ecological compensation standard of 0.81 billion yuan from Beijing and Tianjin.Hydrological regulation was the core ecosystem service in the region,with an average value of 187.974 billion yuan.It was of strategic significance to introduce ecological insurance mechanism to construct horizontal ecological compensation mechanism,improve ecosystem service function,and enhance the value of ecosystem services in the study area.
