枕头坝一级水电站对峡谷视觉景观影响分析

摘要

The construction of hydropower stations and dams will inevitably change the visual landscape of river valley. By adopting a series of measurable parameters, including the loss of vision, the visual impact range of dam and the loss of discrepancy in elevation, and by using GIS, the visual impact of the construction of Zhentouba Hydropower Station on the landscape of Dadu River Canyon are analyzed. The results show that the visual impact of Zhentouba Project on canyon's landscape is very small.%水电站大坝建设不可避免地会改变峡谷视觉景观.为此,通过采用可视域损失、大坝视觉影响范围、高差损失等一系列景观测度参数,并利用地理信息系统(GIS)进行模拟,分析枕头坝一级水电站建设对大渡河峡谷整体和局部景观的视觉影响.结果表明,处于典型高山峡谷区的枕头坝一级水电站对整个大峡谷视觉景观影响很小.
