香港新区中的“街墙”问题及其成因

"Street Wall" in Hong Kong's New Towns

与香港许多旧城区富有活力的街道界面相比,某些新区中出现了相对封闭的街道界面,就像一道"街墙"那样在人行道旁延伸,导致街道活力很大程度上被削弱。在前人的研究以及调研的基础上,本文中运用首层功能的多样性、建筑入口的密度、活动的混合性以及人行道的品质这四个评价标准来比较香港六个调研地点的街道界面,从而探讨建筑类型的演变、机动化主导的街道以及当地政府相关规范条例这三要素是如何相互作用并共同影响着街道界面的。

Today, compared with vital street interfaces in the old district, a number of relatively isolated street interfaces in the new towns present the aspect of a＇street wail＇beside the sidewalk. This kind of new street interface is taking away the vibrancy of the neighbourhood and providing fewer pleasant street experiences for the pedestrian. Furthermore, this design seems to be increasingly prevalent in new towns in Hong Kong. Based on the site research and precedent, new criteria will be created to assess the quality of the existing street interface in Hong Kong, which includes assessment of the diversity of functions, the density of building entrances, the mixture of activities and the physical quality of the sidewalk. The building typology, vehicle-orientated streets and relevant governmental policies in Hong Kong have had a significant impact on this passive street interface, not only working cooperatively but also interplaying with each other at the same time.
