【摘要】：以九寨沟自然保护区为例,基于生物物理因素,提出景观视觉吸收力评价体系(VAC)。运用Delphi法建立各指标权重,分析了景观基底中坡度、坡向、地形起伏度、植被丰富度、植被格局和土壤稳定性六要素对景观视觉吸收力的影响。结果发现,保护区不同区域带给游客的视觉感受差异很大,其中以纳西寨和树正寨区域VAC最好;公路沿线的中景范围不同路段VAC变化较为稳定,且较近景范围的值高。景观视觉吸收力最直接的影响因素是植被丰富度,植物群落成分越丰富、结构越复杂,VAC也越高。客观评估景观视觉吸收力可以指导相关部门更好地进行景观规划和开发决策。
[Abstract]:Taking Jiuzhaigou Nature Reserve as an example, based on biophysical factors, the evaluation system of landscape visual absorbability is put forward. The weight of each index is established by using Delphi method, and the slope, slope direction, topographic fluctuation and vegetation richness in the base of landscape are analyzed. The influence of six factors of vegetation pattern and soil stability on the visual absorbability of landscape was found. The results showed that there were great differences in the visual perception of tourists in different areas of the reserve, among which the VAC of Naxi village and Shunzheng village was the best. The variation of VAC in different sections along the highway is more stable and higher than that in the close-range. The most direct influence factor of landscape visual absorbability is vegetation richness, and the more abundant the plant community is, the more the plant community is. The more complex the structure, the higher the VAC. Objective evaluation of the visual absorbability of the landscape can guide the relevant departments to make better landscape planning and development decisions.
