基于景观敏感度的猴石森林公园保护区划

基于GIS技术，选取坡度、相对景点距离、相对游道距离、景点视觉几率和游道视觉几率5个指标分别对猴石森林公园进行敏感度评价，并建立了综合敏感度评价模型，运用层次分析法（AHP）确定各指标权重，进而确定了公园内各区域的综合敏感度等级，将公园相应地划分为4个等级的敏感区.结果表明：研究区Ⅲ级敏感区的面积最大，为495.80 hm²，占公园总面积的38.3%.这一区域在强调保护自然景观的同时，可进行适度开发，提倡利用人文景观美化和衬托自然景观.Ⅳ级敏感区的面积最小，为142.80 hm²，占研究区总面积的11.0%.这一区域的开发潜力最大，可开展大规模的综合性旅游设施和游道布设.Ⅰ、Ⅱ级敏感区的面积依次为297.24和359.72 hm²，分别占研究区总面积的22.9%和27.8%，Ⅰ级敏感区内景观应严格保护，禁止任何人为开发建设，维持自然景观的本色，Ⅱ级敏感区内除简易的林间小道和石阶山道外，严禁开山取石、破坏植被和水体.

Protection regionalization of Houshi Forest Park based on landscape sensitivity.

By using GIS technology, and selecting slope, relative distance to viewpoints, relative distance to tourism roads, visual probability of viewpoints, and visual probability of tourism roads as the indices, the landscape sensitivity of Houshi Forest Park was assessed, and an integrated assessment model was established. The AHP method was utilized to determine the weights of the indices, and further, to identify the integrated sensitivity class of the areas in the Park. Four classes of integrated sensitivity area were divided. Class I had an area of 29724 hm2, occupying 229% of the total area of the Park, which should be strictly protected to maintain natural landscape, and prohibited any exploitation or construction. Class II had an area of 35972 hm2, accounting for 278% of the total. The hills in this area should be kept from destroying to protect vegetation and water, but the simple byway and stone path could be built. Class III had an area reached up to 49580 hm2, occupying 383% of the total, which could be moderately exploited, and artificial landscape was advocated to beautify and set off natural landscape. Class IV had the smallest area (14280 hm2), accounting for 11% of the total, which had the greatest potential of exploitation, being possible to build large-scale integrated tourism facilities and travelling roads.
