摘要: 景观敏戚度是景观被注意到的程度的量度,景观阀值是景观对外界干扰的抵御能力的量度,它们是风景旅游区景观保护规划的基本依据。以南太行山峡谷景观为例,文章探讨了景观敏感度和景观阀值的评价原理与方法,以及基于达两项评价的景观保护规划。

关键词: 景观敏感度, 景观阀值

Abstract: Landscape sensitivity is a measure of the probability of a landscape being noticed. It is a function mainly of the following factors, slope relative to the observer, distance from the view point, probability that the landscape could be seen and visual contrast level of the landscape with its surroundings, A landscape as a visual system and an ecosystem has some capacity to absorb, assimilate, and recover from, visual and ecological .mpact caused especially by human activity, and this capacity of landscape is measured by impact resista-bility which can be effectively assessed according to slope, aspect and other landform characteristics. The assessment of landscape sensitivity and impact resistability, together with the assessment of landscape quality, are the bases of landscape preservation planning.
