旅游地生态安全评价模型及实证研究——基于生态足迹模型的分析

根据生态足迹模型,构建了旅游地生态安全评价的指标体系和方法,并以人均旅游生态足迹和人均旅游用地承载力的比值I来确定旅游地生态安全的状况。以开封市为研究区域,采用以上指标体系,对2005年开封市旅游生态安全状况进行了评价。研究结果表明:2005年开封市人均生态旅游足迹为0.02361hm2,其中交通足迹最大,占到88.9%;其次是餐饮,为7.72%。人均旅游用地承载力为0.04180hm2,生态安全度为0.56,处于一种一般状态或者说较为安全的状态。通过计算也发现开封市旅游生态安全度在增大,说明旅游活动对生态系统的压力越来越大,因此,关注旅游生态问题应当成为旅游可持续发展的一个关键问题。最后对模型的应用前景和问题进行了讨论。

ECOLOGICAL SECURITY EVALUATION OF TOURISM DESTINATION BASED ON ECOLOGICAL FOOTPRINT ANALYSES

Assessing ecological security of tourism destination has an important meaning of theories and practice and it is a precondition and foundation to study ecological security.Based on ecological footprint model,the paper designed a series of indexes system to assessing ecological security and set up a ratio I to make sure the situation of ecological security.Took Kaifeng city as an example,adopted the method of ecological footprint analyses and constructed evaluation method and indexes system.The result showed: Average ecological footprint of every person was 0.02361hm~2 in 2005,among transport was 88.9%,next food and drink was 7.72%.Average person tourism land carrying capacity was 0.04180hm~2 and ecological security degree was 0.56 which showed it was in a more safe condition.Compare to tourism environment capacity and synthetically indexes method,the result was more reasonable.Some problems and application foreground were also analyzed.
