摘　　要：针对早期快速城镇化发展建设对生态自然资源关注不足,导致以堤防为代表的单纯工程手段严重影响滨水地区高品质空间建设的问题,结合基于自然的解决方案,提出通过有效协同滨河多元空间要素、多级空间尺度与多元功能需求,实现堤防工程的适应性转型,使其从“工程抑制自然”走向“工程成就自然”。同时,结合钱塘江堤防提升改造实践,根据流域基本情况,探讨基于自然解决方案的堤防提升改造规划路径,提出“纵向统筹区段,横向整合要素”“建构梯度分层的管控体系”“设计赋能落实场景”3大规划路径,以期补充基于自然的解决方案在具体操作框架上的不足,推进其在我国本土发展落地。Since ecological and natural resources were not paid due attention at the early stages of urbanization,pure engineering solutions represented by river dikes have hampered the quality development of waterfront spaces.Based on Nature-based Solutions(NbS),coordinating the multiple spatial elements,multilevel spatial scales and multiple functional needs for the adaptive transformation of river dikes from"engineering restrains nature"to"engineering makes nature"is proposed.Taking the practice of Qiantang river dike upgrading and reconstruction as an example,three planning paths are proposed:integrating horizontal elements and vertical sectors,establishing gradient governance system,design empowering implementation,in order to complement NbS in the specific operational framework of the deficiencies,and promote its implementation in China.
