生态旅游开发对世界双遗产地植被景观的影响

 采用景观视觉敏感度、植被景观优势度倒数、平均分维数的倒数、景观斑块数量破碎度、景观聚合度倒数、景观多样性指数倒数、建筑面积比及道路廊道密度指数8个指标构建了生态旅游干扰评价模型，评价分析了生态旅游对武夷山世界自然遗产地植被景观的干扰，并首次利用改进单纯形投影寻踪法来对8个模型指标因子进行聚类分级和检验其贡献度水平。结果表明：生态旅游对武夷山世界自然遗产地中大竹岚、先峰岭、挂敦、双溪口景区景观系统干扰较轻，对桃园峪、黄岗山、双泉寺、麻雀观鸟和罗家洞景区干扰较严重，对坳头农家度假村和三岗景区干扰最严重。8个指标表征干扰强度的贡献率的从大到小的顺序为：视觉敏感度指数=植被景观优势度倒数=平均分维数的倒数>道密度指标>景观多样性指数倒数>景观斑块数量破碎度>建筑面积比>景观聚合度倒数。

Eco-Tourism Disturbance of the Wuyishan Natural Heritage Vegetation Landscape

Using S-t-c index,MD index,MFD index,FN1 index,MAI index,MSHDI index,AR index and RU index,the evaluate model of eco-tourism disturbance was created.with the evaluate model,tourism disturbance of the Wuyishan Natural Heritage vegetation landscape was studied,furthermore,Cluster degree and contribution rate of 8 model indices were analyzed by using MSM-PP for the first time.The result showed that: the Dazulan,the xianfengling,the Guadun and the Shuangxikou scenery spots were disturbed lest seriously;the Taoyuanyu,the Luojiadong,the Shuangquansi,the Masu,the Xianfengling and the Huangganshan scenery spots were disturbed less seriously;the Aotou and the Sangang scenery spots were disturbed most seriously.Evaluate disturbance contribution rate of 8 model indices was list as blow:S-t-c index=MD index=MFD index> RU index>MSHDI index >FN1 index>AR index and> MAI index.
