特色塑造下的汉中城市视线体系构建与优化

摘要

The paper takes Hanzhong as an example,constructs and optimizes urban sight system followed the "highlight the pattern of mountain and water,inherit the history and culture,and retain the nostalgia" ideas:firstly,creates 16 sight lines(seven lines of mountain and water,six lines of historical sites,three lines of culture) and 21 sight spots with sight environment evaluation and option distance optimization method;secondly,simulates and analyzes the sight lines with GIS technique,optimizes the sight system with "rule of thirds",sight analysis,and whole sight control,advances the construction of urban characteristic.%文章以汉中为研究对象,在“望山看水显格局、承袭历史筑文韵、沟通古今续乡愁”思想的指导下,对彰显城市特色的视线体系进行构建与优化.首先运用景观视觉环境评价及最佳视距校正法,构建出“七线望山与看水、六处史迹互相望、三条视廊延文脉”等1 6条城市视线及20处视点;其次结合GIS技术,对代表性视线的现状、相关规划等进行空间实景模拟与问题剖析,并运用“三分法则”、视线分析原理及纵横向视域控制等方法与要求,对视线体系进行调整优化,以指导城市特色建设.
