The compensation of upstream protective area should be determined carefully. This paper provides a comprehensive evaluation framework for economic assessments on the treatment of wastewater discharged into a river basin. We explore the rational costs of compensation and the funding allocation in the Xin'an River basin based on rate agreements. The compensation is determined in accordance with the total compensation model based on the opportunity cost method and allocated by the method of information entropy. In this study, we identify the total compensation payment and distribution of funds in each district and county in the upstream area (Huangshan). Results show that the She county can receive the highest compensation, and the Tunxi district deserves the lowest compensation. In addition, this paper demonstrates that the existing compensation is insufficient for the reduction of water pollutants in the upstream area. Our findings contribute to the existing schemes of ecosystem services payment and improve the environmental decision-making.

上游保护区的补偿应谨慎确定。本文为排放到流域的废水的处理提供了经济评估的综合评估框架。我们基于费率协议探讨了新安河流域的合理补偿成本和资金分配。根据总补偿模型，基于机会成本法确定补偿，并通过信息熵方法进行分配。在本研究中，我们确定了上游地区（黄山）每个县和县的总补偿金支付和资金分配。结果表明，She县的补偿水平最高，屯溪地区的补偿水平最低。此外，本文证明了现有的补偿不足以减少上游地区的水污染物。我们的发现有助于现有的生态系统服务支付计划，并改善环境决策。
