中文摘要:

      推进长江流域绿色发展是贯彻落实习近平生态文明思想的重要举措，是新发展阶段贯彻新发展理念的现行实践。本研究解析新时期流域绿色发展内涵，基于“三水”协同理念构建DPSR评估模型，诊断不同流域分区绿色发展水平，分析各评估维度指标灵敏度，开展流域分区类型识别与差异化问题分析，并据此提出差异化环境管理策略。结果表明：①长江流域绿色发展水平呈现W型曲线，上游嘉陵江流域、中游汉江流域的绿色发展水平较低，干流中下游流域绿色发展水平较高。②基于各流域分区指标灵敏度与关键制约不同，可分为保护导向型、治理引导型、协同调控型、效率约束型、提质增效型5种类型，为流域绿色发展差异化环境管理策略提供重要依据。③金沙江等保护导向型流域应重点统筹水资源合理开发利用与经济社会适度发展，岷沱江等治理引导型流域应统筹“三水”协同治理与经济社会高质量发展，汉江等协同调控型流域应协同促进水生态环境保护与经济社会绿色转型发展，洞庭湖等效率约束型流域应统筹水资源利用效率与经济社会跨越式发展，干流中下游等提质增效型流域应协同促进资源循环高效与经济社会绿色低碳发展。

英文摘要:

      Promoting the green development of the Yangtze River Basin is a significant measure for implementing Xi Jinping’ s Thoughts on Ecological Civilization and the current practice of realizing the new development concept in the new stage. This study analyzes the connotation of green development of watersheds in the new period, constructs the DPSR assessment model based on the conception of ‘Three Waters’ overall planning, evaluates the green development level of different watershed zoning, analyzes the sensitivity of indicators in each assessment dimension, then conducts watershed zoning type identification and differentiated problem analysis, accordingly propose differentiated environmental management strategies. The results show that: ①The green development level of the Yangtze River Basin presents a W-shaped curve, and the green development level of the Jialing River in the upper reaches of the Yangtze River and the Han River in the middle reaches is relatively low, while the green development level in the middle and lower reaches of the main river basin is relatively high. ②Based on the different sensitivities and key constraints of the zoning indicators in each river basin, they can be divided into five types: protection-oriented, governance-led, coordinated regulation-led, efficiency-constrained, and quality enhancement-led, which provide an essential basis for differentiated environmental management strategies for green development in the Yangtze River Basin. ③The Jinsha River and other protection-oriented watersheds should focus on coordinating the rational utilization of water resources with moderate economic and social development, the Min River and other governance-led watersheds should integrate the management of ‘Three Waters’ with high-quality economic and social development, the Han River and other coordinated regulation-led watersheds should collaboratively promote the water ecological environment protection and green transformation of economic development, the Dongting River and other efficiency-constrained watersheds should integrate the water resource utilization efficiency with leapfrog development of economy and society, the middle and lower reaches of the mainstream and other quality enhancement-led watersheds should collaboratively promote the efficient recycling of water resources in coordination with the green and low-carbon development of economy and society.
