基于美景度评价的沈阳市城市绿道设计优化研究

Research on Design Optimization of Urban Greenway in Shenyang Based on Scenic Beauty Estimation

摘要:

城市绿道的建设对于提升城市景观质量和居民生活品质具有重要意义，而视觉质量评价是研究者们获取绿道景观价值最直接迅速的方式。以沈阳市沈水湾绿道、五里河绿道、环丁香湖绿道和南 湖公园绿道为研究对象，通过美景度评价对研究区段景观效果进行量化，运用相关性分析及线性回归分析挖掘公众审美与相关景观指标因子的关系。研究结果表明，13 项景观指标均与美景度值 存在正相关关系，景观指标的变化会影响公众对于景观效果的评价，并且集中在安全感、植物景观层次、游憩设施、整洁度 4 项指标。最后，将美景度评价结果应用到城市绿道设计实践中，从 公众核心需求出发，进行多层次植物景观配置，确保视线通透，同时增设场地内部照明设施和游憩设施，做好后期的养护管理工作。

Abstract:

The construction of urban greenway is of great significance to improve the quality of urban landscape and residents' life, and visual quality evaluation is the most direct and rapid way for researchers to obtain the value of greenway landscape. Taking Shenshui Bay Greenway, Wuli River Greenway, Ring Clove Lake Greenway and South Lake Park Greenway in Shenyang City as the objects, this paper quantifies the landscape effect of the study section through the Scenic Beauty Estimation, and mines the relationship between the public's aesthetics and relevant landscape index factors. The results show that 13 landscape indicators are positively correlated with the beauty degree, and the change of landscape indicators can affect the public's evaluation of landscape effect, and focus on the sense of security, the level of plant landscapes, open space facilities, and the degree of cleanliness of the four indicators. Finally, the results of the evaluation of the degree of beauty are applied to the design practice of urban greenways, starting from the core needs of the public, multilevel plant landscape configuration, to ensure that the line of sight is permeable and to increase the site of internal lighting facilities and recreational facilities, as well as to do a good job in the later stages of the maintenance and management work.
