【摘要】：以九寨溝自然保護區(qū)為例,基于生物物理因素,提出景觀視覺吸收力評價體系(VAC)。運用Delphi法建立各指標(biāo)權(quán)重,分析了景觀基底中坡度、坡向、地形起伏度、植被豐富度、植被格局和土壤穩(wěn)定性六要素對景觀視覺吸收力的影響。結(jié)果發(fā)現(xiàn),保護區(qū)不同區(qū)域帶給游客的視覺感受差異很大,其中以納西寨和樹正寨區(qū)域VAC最好;公路沿線的中景范圍不同路段VAC變化較為穩(wěn)定,且較近景范圍的值高。景觀視覺吸收力最直接的影響因素是植被豐富度,植物群落成分越豐富、結(jié)構(gòu)越復(fù)雜,VAC也越高�？陀^評估景觀視覺吸收力可以指導(dǎo)相關(guān)部門更好地進行景觀規(guī)劃和開發(fā)決策。
[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.
