城市型风景区边界街道空间品质测度研究——以承德避暑山庄外八庙风景名胜区为例

Type City Scenic Area Boundary Street Space Quality Measure Research:Taking Chengde Summer Resort Outside Eight Temple Scenic Area as an Example

针对城市型风景区边界城市空间较少考虑观景效果、利用率低、活动不便、吸引力差等问题,以承德避暑山庄外八庙风景名胜区为例,采用主客观相结合的方法对风景区周边具有观景价值的城市街道空间进行量化研究。首先,通过SegNet图像语义分割技术对边界街道空间要素客观构成进行分析;其次,通过线上问卷打分测量公众的审美态度;最后,通过SPSS统计分析对公众主观评价与客观要素的测量值进行相关性分析,即测定心理量和物理量之间的关系,确定哪些空间特征对空间品质产生影响及其影响大小,该研究以期为城市型风景区边界街道空间设计精细化提供参考。

In view of the problems of less consideration of viewing effect,low utilization rate,inconvenient activities and poor attraction in the boundary urban space of urban scenic spots,taking Chengde summer resort outside eight temple scenic area as an example,this paper makes a quantitative study on the urban street space with viewing value around the scenic spot by combining subjective and objective methods.Firstly,the objective composition of boundary street space elements is analyzed by SegNet image semantic segmentation technology;secondly,the aesthetic attitude of the public is measured by Internet scoring;finally,the correlation between the public subjective evaluation and the measured value of objective elements is analyzed by SPSS statistical analysis,that is,the relationship between psychological quantity and physical quantity is measured to determine which spatial characteristics have an impact on the space quality.This study provides a reference for the refinement of space design.
