"2008年，开州区在城区下游乌杨坝区域建成水位调节坝，将汉丰湖水位落差从20多米缩减到5米以 内，消落带面积大大缩小。"开州区水利局副局长李培付指着远处的水位调节坝介绍，"这为后续的生态 修复提供了基础，创造了条件。" 在重庆开州区，汉丰湖国家湿地公园的8784吨碳汇资产以70.3万元的价格成交，达成全国首例水库水生 态碳汇交易。将水生态修复效益转化为可量化的碳资产，为全国水库水生态价值实现提供了可借鉴的案 例，也为长江经济带生态修复与碳汇能力提升开辟了新路径。 冬日，重庆开州汉丰湖国家湿地公园内，湖水波光粼粼，远处山峦薄雾笼罩，一幅山水画卷映入眼 帘。 "以前这里是一片荒滩，谁能想到现在竟然成了宝地，能产出'碳票'赚钱呢！"市民陈冠军感慨。 陈冠军口中的"碳票"，源于去年达成的全国首例水库水生态碳汇交易。2025年6月16日，汉丰湖国 家湿地公园的8784吨碳汇资产，以70.3万元的价格被三峡新能源淮南光伏发电有限公司认购，标志着水 利工程探索建立水生态产品价值实现机制迈出重要步伐。 水生态变现，为什么能在汉丰湖实现？这要先从持续了近20年的生态修复说起。 汉丰湖，三峡工程孕育出的内陆人工湖。15平方公里 ...

Core Viewpoint - The first water ecological carbon trading in Chongqing's Kaizhou District has successfully transformed ecological restoration benefits into quantifiable carbon assets, providing a replicable model for ecological value realization in water reservoirs across the country [3][6]. Group 1: Carbon Trading Details - The carbon asset of 8,784 tons from Hanfeng Lake National Wetland Park was sold for 703,000 yuan, marking the first water ecological carbon trading in China [3][4]. - The transaction was completed by Three Gorges New Energy Huainan Photovoltaic Power Co., which aims to alleviate future carbon emission control pressures during capacity expansion [7]. Group 2: Ecological Restoration Efforts - The ecological restoration efforts in Hanfeng Lake have been ongoing for nearly 20 years, with an investment of 2.49 billion yuan from the Three Gorges follow-up work special fund [4][5]. - The restoration includes the construction of water level regulation dams and the establishment of ecological restoration zones, which have significantly improved biodiversity and reduced soil erosion [4][5]. Group 3: Future Implications - The transaction is seen as a comprehensive value transformation model, integrating ecological restoration, carbon accounting, market trading, and funding reinvestment [7]. - The Ministry of Water Resources plans to develop guidelines for carbon monitoring, accounting, and assessment based on the Hanfeng Lake practice, aiming to enhance the carbon trading system for large and medium-sized reservoirs [7].
