长江经济带是我国区域经济发展的重要增长极。党的十八大以来，习近平总书记多次召开座谈会，为长 江经济带发展谋篇布局、把脉定向。沿江省市探索生态优先、绿色发展新路径，推动生态环境保护和修 复取得重大成就，发展方式发生重大变革，区域协同联动不断加强。"十五五"规划建议提出"持续推进 长江经济带发展"。如何推动长江经济带高质量发展不断取得新进展？本期特邀专家围绕相关问题进行 研讨。 推动长江经济带发展，生态优先是前提。长江经济带生态状况如何？生态环境保护和修复取得了怎样的 成效？ 董战峰（生态环境部环境规划院生态环境管理与政策研究所所长）：长江经济带横跨我国东中西三大板 块，覆盖沿江11省市，生态地位突出。长江流域拥有全国1/3水资源和3/5水能资源储备总量，河湖、水 库、湿地面积约占全国的20%，森林覆盖率达41.3%，分布有全国约51%的国家级水产种质资源保护 区、33%的淡水鱼类以及39.7%的珍稀濒危植物。长江经济带覆盖约21%的国土面积，经济总量占全国 比重超46%，是我国经济重心所在、活力所在。 然而，长期粗放式发展曾使得长江不堪重负，生态环境透支问题凸显。从长远来看，推动长江经济带高 质量发展，根本上依 ...

三是把强化区域协同融通作为着力点，下好流域治理"一盘棋"。长江经济带区域空间回旋余地大，沿江 省市要坚持省际共商、生态共治、全域共建、发展共享，增强区域交通互联性、政策统一性、规则一致 性、执行协同性，推动上中下游之间产业合作互动，不断拓展区域发展新空间，形成溯江而上梯次发展 态势，着力增强绿色低碳高质量发展的韧性和可持续性。发挥长江串联长江三角洲城市群、长江中游城 市群和成渝城市群"三极"的作用，构建以中心城市引领城市群发展、城市群带动区域发展的新模式，激 发区域联动发展内生动力。完善区域一体化发展机制，构建跨行政区合作发展新机制，健全区际利益补 偿机制，推动建立跨行政区合作的规划统筹、产业协作、成本共担、利益共享机制，稳步推进生态共同 体和利益共同体建设，在协同联动中"握指成拳"，携手加强生态保护治理，共同促进全流域高质量发 展，联合改善民生福祉，让长江成为造福人民的幸福河。 （作者系中国宏观经济研究院国土开发与地区经济研究所综合研究室主任、研究员） （文章来源：经济日报） 面向"十五五"，要在高水平保护上下更大功夫，在绿色转型中加快孕育生成新质生产力，不断以生 态"含绿量"提高经济发展"含金量"，确保一 ...
