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.
