【摘要】 选择嘉陵江流域四川段10个主要旅游景区作为研究对象,采用Delphi法将旅游景区生态位分为"态"和"势"两部分,运用AHP法获取旅游景区生态位评价指标的权重,确定了旅游景区的生态位评价指标体系,基于生态位理论测定嘉陵江流域10个主要旅游景区的生态位宽度及生态位重叠值。结果表明:九寨沟在旅游资源条件、旅游市场状况、旅游服务、生态环境质量及综合生态位等的分值均居于首位,分别为0.1470、0.1855、0.1480、0.1477和0.1570,诺水河景区生态位宽度最小为0.0676;九寨沟与唐家河保护区的重叠值最高为0.6856,最低重叠值则为九寨沟与大英死海0.3514;通过进一步计算得知,重叠度>0.5的占所有值的48%,嘉陵江流域主要旅游景区综合重叠度呈现局部较高、总体不高的状况。更多还原

【Abstract】 Ten major tourist attractions along the Jialing River in Sichuan Province were selected as the study objects.By using Delphi method,the niches of the tourist attractions were divided into "state"and "potential",and the weights of the niche evaluation of the tourist attractions were obtained by applying AHP.Consequently,the niche evaluation index system of the tourist attractions was determined.Based on niche theory,the niche breadth and niche overlap values of the 10 major tourist attractions were investigated.The results showed that in Jiuzhaigou,the values of tourism resources,tourism market,tourism services,environmental quality,and comprehensive niche were 0.1470,0.1855,0.1480,0.1477,and 0.1570,being the highest among the ten tourist attractions;while Nuoshui River had the lowest scores,with the minimum niche breadth of 0.0676.The niche overlap value of Jiuzhaigou and the Tangjiahe Reserve was the highest(0.6856);while that of Jiuzhaigou and the Daying Dead Sea was the lowest(0.3514).Further calculation showed that the degree of niche overlap greater than 0.5 reached 48% of the total,which meant that the comprehensive niche overlaps of the main tourist attractions in Jialing River Basin were locally high,but not totally high.更多还原
