基于GIS的输变电项目对风景名胜区景观的影响研究

Landscape impact caused by transmission projects in scenic area based on GIS

基于ArcGIS三维空间分析,以穿越贡嘎山风景名胜区的110千伏异地重建输变电工程为例,运用景观生态学原理分析了输变电项目对风景名胜区景观的影响。分析认为:输变电工程施工期永久侵占现有斑块将会长期干扰景观体系,该工程在异地重建远离了田湾河和令牌山景点,对景观资源的影响有所减少;按照近景带、中景带、远景带、不可见区域的划分原则,异地重建减少了对景观敏感度的影响。

Taking a 110 kV reconstruction transmission project across Minya Konka Mountain as an example,landscape impacts of transmission projects in scenic area were studied using the principles of landscape ecology based on ArcGIS 3D analysis.It was considered that occupying existing patches permanently during the construction period of transmission projects will affect the landscape system for a long time.This 110 kV transmission project caused less impact than others because it was rebuilt far away from Tianwan River and Lingpai Mountain.Thus,rebuilding in other place reduced the impacts of transmission projects on landscape according to the division principle of close-shot,mid-shot,long-shot and invisible area.
