基于LCA的森林景观的旅游生命力评价——以张家界市武陵源区为例

根据森林旅游资源具有生命周期的特点,引入环境评价中的生命周期评价方法与步骤,并利用生命周期矩阵的半定量方法,对森林景观进行生命力评价。结果表明:(1)各个景观所表现出的生命力,在森林景观自身的功能基础上,取决于生命周期的各个阶段的旅游魅力,生命力评价指数和常绿阔叶林景观的相关性,说明了常绿阔叶林景观的旅游魅力;(2)森林景观应按照年龄结构进行合理的空间格局配置,以提高旅游吸引力;(3)提高森林景观的旅游生命力,必须调整资源类型结构,尽量扩大高质量的森林景观种类比例,优化树种结构。

The Evaluation of the Vitality of Forest Tourism Resource Based on LCA Matrix: A Case Study of Wulingyuan Scenic Spot in Zhangjiajie City

The methods of life cycle assessment(LCA) coming from environmental evaluation,with the semi-quantitative methods of LCA matrix,are introduced to evaluate the vitality of the forest landscapes.The conclusions are: 1)The vitality of forest landscape lies on the tourist charm in various stages of the life cycle.In mature stage,the evergreen broadleaf forest has higher evaluation index,which can reach 0.66,and the correlationship between the evaluation index of the vitality and the evergreen broad-leaf forest landscapes indicates that the evergreen broadleaf forest has higher tourist charm.2) The forest landscapes should be reasonably distributed according to their age structure in order to improve their attraction to tourists.3)For improving the vitality of the forest tourism landscape,the structure of resource types should be adjusted,the proportion of the high-quality forest landscape types be raised,the structure of species be optimized.
