This article analyses the spatiotemporal evolution (spanning 1956 to 2016) of two large bays located on the Costa Brava coast: the Gulf of Roses and Bay of Pals (NW Mediterranean, Spain). This research demonstrates how the status of dunes is related to management measures. For this purpose, a matrix of 11 variables was used to assess the management procedures and geo‐environmental conservation status of each sector. The 12 beach‐dune systems assessed have been classified into four stages according to their degree of degradation over time: 1—systems in a natural state (two beaches), 2—very altered or disappeared dune systems (three beaches), 3—remaining systems (three beaches), and 4—systems in recovery state (four beaches). The results show that well‐conserved and recovered dunes are strongly associated with management measures such as rope off dunes, managed paths, and lack of mechanical cleaning. On the contrary, remaining and beaches where dunes have disappeared are located in urban or semiurban areas associated with a lack of management measures. The sustainable and soft management actions applied during the recent years in the studied area have led the dunes toward their recovery after degradation caused by visitors.

利用管理标准评估海滩-沙丘系统地貌状态的时空

本文分析了布拉瓦海岸沿岸的两个大型海湾（玫瑰湾和帕尔斯海湾）（西班牙西北地中海）的时空演变（从1956年到2016年）。这项研究表明了沙丘的状态与管理措施之间的关系。为此，使用11个变量的矩阵来评估每个部门的管理程序和地球环境保护状况。评估的12个海滩沙丘系统根据它们随时间的退化程度分为四个阶段：1-自然状态的系统（两个海滩），2-沙丘系统变化或消失的非常多（三个海滩），3-剩余的系统（三个海滩）和4个处于恢复状态的系统（四个海滩）。结果表明，保存完好的沙丘与诸如沙丘拉索，管理路径和缺乏机械清洁等管理措施密切相关。相反，沙丘消失的剩余和海滩位于缺乏管理措施的城市或半城市地区。近年来，在研究区采用的可持续和软管理措施使沙丘在游客造成的退化后得以恢复。
