Abstract:
In the renewal and revitalization of historical and cultural blocks, green plants play an important role in improving the walking experience. How to strike a balance between better green view experience and less land occupation areas has attracted much academic attention. The existing researches are largely based on the evaluation of walkability around the subject, but lack analysis of walking visual perception from the perspective of the object. Taking Tongwen area of Zhongshan Road Historical and Cultural Block in Xiamen as an example, this paper measures green view rate of roads in the block, and draws the “green view attenuation curve” of greening modules, proposing a method for calculating the maximum green view range. The result shows: 1) Arbor-shrubs, arbor trees and street greening fit better with the power-law fitting model, while potted plants and vertical greening fit better with the exponential fitting model. The maximum green view range from high to low is arbor-shrubs, arbor trees, street greening, vertical greening and potted plants. 2) There is much room for improvement the green view along Zhongshan Road – Siming South Road, and the green view rate along Lujiang Avenue – Zhenhai Road is high. While Qingshi Lane, Tongwen Road and Taishan Road have good green view levels, Qianluhuicheng Lane, Diaozai Road, Shuixian Road and Ding’an Road have poor green view levels. 3) The layout of greening facilities reduces the attraction of heritage elements to visitors, while commercial atmosphere has weakened visitors’ perception of the block’s cultural elements. This paper aims to make green view rate two-dimensionalize, and provide a new perspective for quantitative research and application of green view rate.
