蓝色空间在缓解精神压力和恢复心理健康方面具有重要潜能。选取海口市滨海型蓝色空间，通过语义分割图像处理、场地评价、问卷调查等方法获取空间特征及公众心理健康恢复性评价数据，探讨不同蓝色空间恢复性评价以及空间特征因子对恢复性环境的影响效应。结果表明：植物、水体等空间自然元素丰富、休憩设施等空间特性要素完备的滨水空间恢复性效应更佳；蓝视率、植物丰富度、休憩设施对热带滨海蓝色空间恢复性效应具有显著影响。基于研究结果，提出优化热带滨海空间元素配置，提升热带城市蓝色空间品质，调整恢复性环境空间布局等优化策略。

Blue spaces have important potential in relieving mental stress and restoring psychological health. This paper selects coastal blue spaces in Haikou, obtains the spatial characteristics and public mental health restorative evaluation data through semantic segmentation image processing, site evaluation, questionnaire survey and other methods, and explores the restorative evaluation of different blue spaces as well as the influence effect of spatial characteristic factors on the restorative environment. The results show that the restorative effect of waterfront space is better when plants, water bodies and other spatial natural elements are abundant, and when spatial characteristics such as resting facilities are complete. Meanwhile, blue vision rate, plant richness and resting facilities have significant effects on the restorative effect of tropical coastal blue space. Based on the research results, optimisation strategies are proposed to optimize the configuration of tropical coastal spatial elements, improve the quality of blue space in tropical city, and adjust the spatial layout of restorative environment.
