文山州砚平高速公路造林景观提升策略研究

Research on the Promotion Strategy of Afforestation Landscape along Yanping Expressway in Wenshan Prefecture,Yunnan

文章以云南省文山州砚山—平远段高速公路为研究对象,结合山地造林与景观设计思维,探索喀斯特地貌特征下的高速公路两侧重点可视范围内造林景观的提升策略。研究通过现场调研,结合卫星影像图及GIS矢量数据的方式,区划现状景观斑块,分析现状景观特征及问题;在此基础上对应“面”“线”“点”结合的空间布局形式提出相应的提升策略。针对“面”,制定基础配置模型,并分区段确定景观主题及配置组合;以“点”形成景观提升示范节点,并引导区域建设;以“线”形成景观林带,将现状破碎化的景观进行有机联系,最终实现沿线景观的提升。

This paper takes the expressway from Yanshan to Pingyuan in Wenshan Prefecture,Yunnan to explores the strategy for afforestation landscape improvement along the expressway in Karst area within the key visual range from the perspective of afforestation in hilly area and landscape design. The satellite image,GIS data and site survey are adopted to determine the landscape patches for landscape characteristics analysis and problems identification. On this basis,the corresponding strategies for improving spatial layout forms of"point","line"and"surface"are proposed.In the strategy for"surface",the basic configuration model should be developed for identifying landscape theme and model combination pertinently for different sections of the expressway. "Line " is used to link the fragmented landscape into a landscape forest belt. "point"is taken as the demonstration of landscape improvement and used for guiding regional construction.
