拉萨江苏大道城市设计中建筑高度的控制

景观视线的控制是城市设计中经常遇到的问题，在拉萨市江苏大道的设计中，针对大道的位置特点，将其与布达拉宫的视线关系确立为城市设计的原则之一，通过建筑高度的精确控制，确保布达拉宫成为江苏大道的对景。分别采用GlS和AutoCAD编程对建筑控高进行计算，并介绍了控高计算的思路和方法。分析了各自的优缺点，希望为相关研究提供参考。

Building Height Control Based on Sight Line in the Urban Design of Jiangsu Avenue,Lhasa

Sometimes the control of sight line plays a key role in urban design.In the urban design of Jiangsu Avenue of Lhasa,one of the goals was to ensure Potala Palace as the scenic focal point along the avenue through the precise control of building height.For this we respectively used GIS and AutoLISP programming to calculate.This paper introduces the principle and method of our calculation, and compares the merits and demerits of the different means,hoping to offer a reference for similar researches.
