摘　　要：在我国高密度历史文化街区更新改造过程中,道路的规划与生成是非常重要的问题。作者以西安碑林历史街区为例,研究探讨了高密度历史文化街区更新改造中的道路生成方法。在根据场地建筑状况得到二维栅格地图后,利用A*寻径算法,得到游客、居民道路的较优解法,并通过不同方式将两种道路在形式上编织,最终形成点、线、面多维编织的局面。本文希望借助软件和程序,为高密度历史街区更新改造中不同类型道路的生成提供更理性的方法,并期待这一成果能在更大尺度、更多类似的项目中有推广的价值。In the process of renovation of high-density historical and cultural blocks in China,the planning and generation of roads are very important issues.Taking Xi’an Beilin historical block as an example,the author studies and discusses the road generation method in the renovation of high-density historical and cultural blocks.After the two-dimensional raster map is obtained according to the site construction condition,the A*path finding algorithm is used to obtain the better solution of the tourist and resident roads.And then these two kinds of roads are weaved in different styles to form a multidimensional weaving situation of point,line and surface.With the help of software and program,this paper hopes to provide a more rational method for the generation of different types of roads in the renovation of high-density historical blocks and expects that this achievement can be popularized in larger scale or more similar projects.
