生态产品能够实现价值转化的前提,是拥有扎实、可衡量的生态本底。沂源县龙子峪小流域的"绿色碳 库"则源自一场近30年的"生态治理行动"。 龙子峪小流域位于沂源县西部,总面积28.93平方公里,涉及7个行政村。上世纪90年代综合治理前,这里水 土流失面积达23.14平方公里,占总面积的79.99%。荒山裸露、植被稀疏,是北方土石山区水力侵蚀类型 区,属于沂蒙山泰山国家级水土流失重点治理区。"晴天一身土、雨天一身泥"是当地百姓最深刻的记 忆。 面对严峻形势,沂源开启了水土保持综合治理系统工程。"自1998年以来,累计投资1983.9万元实施了4轮 水土保持工程,通过实施坡改梯、退耕还林、人工抚育管护、拦沙蓄水工程等水土保持措施,全面开展水 土流失综合治理。"沂源县水利事业服务中心主任李爱学介绍,沂源还建立起了政府主导、部门协作、全 社会参与的水土流失防治机制,引导社会资本投入3000余万元,对该小流域进行配套提升。 一份价值150万元的交易合同,将沂源县龙子峪小流域积攒了二十余年的"绿色碳库"转化成真金白银。 2024年11月,山东省首单水土保持碳汇交易在淄博市沂源县正式签约。沂源县龙子峪小流域通过水土流 失综合治 ...
