水源地生态补偿标准动态测算模型及其应用

为响应政府号召、提供水源地保护环境经济手段支撑，在对现有生态补偿标准核算方法研究总结的基础上，提出水源地生态补偿标准动态测算模型，并应用于鹤地水库水源地生态补偿标准测算中.水源地生态补偿标准动态测算模型是把生态补偿过程分为试行?修复?稳定3个阶段，根据阶段特点及目标的不同，采用相应的测算方法：试行阶段采用条件价值评估法，修复阶段采用基于总成本修正模型和水资源价值法的博弈模型，稳定阶段采用水质污染赔偿法.结果显示，鹤地水库生态补偿试行阶段期限为2015年~2017年，补偿标准总额为14.4亿元；修复阶段期限为2018~2020年，补偿标准总额为89.4亿元；稳定阶段为2021年后，需每年计算补偿标准.水源地生态补偿标准动态测算模型实现了生态补偿标准核算的动态化，且该模型采用的具体核算方法认可度高?应用广泛?计算简单，便于推广.

Development and application of the dynamic calculation model for proposing a water source eco-compensation standard

To follow the government policy and provide environmental-economic measures for protecting the environment at water source regions, the Dynamic Calculation Model was developed for proposing a water source eco-compensation standard by studying and summarizing existing eco-compensation standard accounting methods. The model was applied to establish the standard of water source eco-compensation policy for the Crane Reservoir. The Dynamic Calculation Model divided the ecological compensation process into three stages:trial stage, restoration stage, and stable stage. Depending on the phase characteristics and targets in each stage, respective calculation methods were adopted:the trial stage uses the Contingent Valuation Method, the restoration stage used the Game Model based on the Correction Total Cost Model and the Water Resources Value Method, and the stable stage adopts the Water Pollution Compensation Method. The results show that the trial period of crane reservoir eco-compensation was from 2015 to 2017, and the eco-compensation standard was 1.44billion yuan. The restoration period was 2018~2020, with an eco-compensation standard of 8.94 billion yuan. The eco-compensation standard of stable stage could be calculated annually after 2021. Since the Dynamic Calculation Model proposes water source eco-compensation standards by the dynamic accounting that were with highly recognition, widely application, and simply calculation, this model could be easily promoted.
