乡村道路形态参数化解析与重构方法

摘要

为了精确传承乡村道路空间形态特征,提高规划的科学性,将具有精细尺度解析特征的参数化技术引入到道路形态规划之中.构建道路空间形态解析与重构的技术模型,提出控制道路生成的参数集、参数值的提取算法和道路形态重构方法.同时,从功能与形态2个维度提出相似度评价指标和评价模型对重构前后道路空间形态进行评价,以此验证解析与重构方法的合理性与有效性,并利用2个典型村落进行实证.结果表明:参数化解析与重构方法能够获得与原始空间形态相似度较高的道路空间方案,对于村庄道路形态设计具有一定的参考和辅助作用.%A parametric technology with fine sacle analysis was introduced into the road morphology planning to correctly inherit the character of road morphology and make the planning more scientific.A road morphology analysis and reconstruct technology model was formed.Parameter set to generate the road morphology, calculation of the parameters, and method to reconstruct road morphology was also put forward.At meantime, from the perspective of function and form, a evalution model and some evalution indexes were put forward to test and verify the validity and rationality of analysis and reconstruct method, also an empirical research of two classical villages was taken.Results show that the parametric analysis and reconstruction method can get the road morphology that is extremely similar to original texture shape, providing certain reference and auxiliary function to the road morphology design.
