| 摘 要： | 深圳湾经过近三十年的围填海活动，沿岸动力条件发生较大变化，如今自然状态下难以发育沙滩。从构建高品质游憩空间、防护海岸和提升旅游开发价值来看，沙滩是深圳湾急需的资源。为了加强人和海洋的联系、激发深圳湾的活力，建立城市自然缓冲区、化解极端风暴的威胁，以此达到防护海岸和满足居民休闲游赏需求的目的，本研究以近岸海洋要素的自然属性为主，海洋开发活动等社会属性为辅进行综合分析，并辅以数值模型进行验证，在深圳湾内选择适宜开展沙滩修复的海岸。沙滩修复选址时考虑了波浪、潮流、地形、地貌、沉积物等近岸海洋要素；数值模型包括潮流场模型、波浪模型和沙滩长期的平面演化模型。本研究案例对岸线动态变迁较大，自然状态难以发育沙滩的海岸的人造沙滩选址和设计方案提供示范与借鉴。

| Abstract: | After 30 years reclamations on the sea beach in Shenzhen Bay the beach development is retarding under natural conditions due to the weakening dynamic changes along the coast areas. In perspective of high-quality recreational space, tourism values and the coast protection, the beach areas are urgently needed in Shenzhen Bay. In order to strengthen the relation between human and the sea for the vitality of Shenzhen Bay, it is necessary to establish an urban natural buffer zone and ward off the threat of extreme storms in view of coastal protection and entertainments of residents. Therefore, we select a coastal area more suitable for beach nourishment in Shenzhen Bay based on natural attributes of near shore marine elements and social attributes such as marine development activities for verification with numerical models. The coastal marine elements considered in the beach restoration include waves, tidal currents, topographic features, sediments, etc. The numerical models used include velocity change, wave and long-term spatiotemporal evolution of the beach. This paper provides demonstration and reference for the site selection of beach nourishment and the restoration scheme of artificial beach in coastline where much dynamic change occurred and was unable to develop under natural conditions. |
