基于视听景感的大连滨海步道景观风貌研究

Research on Landscape Feature of Dalian Coastal Trail Based on Audiovisual Perception

城市滨海步行空间是海滨城市重要的开放空间。目前城市滨海步行空间的滨海风貌特色缺失及声环境恶化等问题仍待解决,视听环境质量是影响城市滨海空间品质的重要因素。本研究将大连市6个典型的滨海旅游景区步道划分为四种步行空间类型,主要通过视听景感问卷调查、层次分析法(AHP)等确定旅游者对各类型滨海步道景观风貌的评价因子与感知差别。结果表明:海景纵深层次、步道植物绿化、亲水设施配置、自然声源感知四个景观风貌因子权重最高;盘山型步道的景观风貌综合评价最低,亲水型步道景观风貌得分最高。相关结论可以为城市滨海景观风貌质量提升和步行游观空间设计优化提供参考。

The urban coastal pedestrian space is an important open space in coastal cities.At present,the lack of coastal features and the deterioration of acoustic environment in urban coastal pedestrian spaces still need to be addressed.The quality of audiovisual environment is an important factor affecting the quality of urban coastal spaces.In this paper,the 6 typical coastal scenic walks in Dalian are divided into 4 different types of walking space.The evaluation factors and perception differences of the tourists towards various types of coastal walk landscape features are determined by audiovisual landscape perception questionnaire investigation and analytic hierarchy process(AHP).The results show that the evaluation factors of skyline depth levels,walk plant greening,hydrophilic facilities,and natural sound sources have the highest weight.The landscape quality score of the coastal trail is the lowest for the hilly walk,and the highest for the hydrophilic type trail.The relevant conclusions can provide a reference for improving the quality of urban coastal landscape and for optimizing the design of pedestrian tourism space.
