量形适配,精细管控——三分法则高度控制在南京幕府山天际线风貌保护中的实践探索

The Delicacy Control of Building Height in Consideration of Mountain Landscape and Development Capacity A Practical Exploration of One-Third Height Control Rule in Preserving the Mufu Mountain Skyline in Nanjing

三分法则是我国山景天际线塑造中应用最广泛的建筑高度控制方法,但也面临着高度可视标准多变、水平适用范围不明的问题。理论部分指出三分法则的本质在于风貌保护与建设开发的均衡,从“纵向可视高度”与“横向控制区间”两方面做出精细设计。实践部分针对南京幕府山天际线展开项目实证探索,尝试对控制区间与可视高度做出量形适配下的统筹考虑,并对其中涉及的多类别风貌展示、现状建筑影响等个案问题做出应对。

One-third height control rule is the most widely used method in mountain skyline design for building height control in China,despite problems of variable height-visible standards and unclear horizontal application range.In the theoretical part of this paper,it contends for the essence of the rule as to match mountain landscape with development capacity,hence the delicacy design resulted from both height visible standard from vertical direction and application range from horizontal direction.In the practical part,it carries out an empirical study on Mufu mountain skyline in Nanjing,which systematically tries to complete the design aiming at the matching goal stated above,with solutions to individual cases as affected by presenting various kinds of landscapes and current architectural conditions.
