Abstract: TCM (Travel Cost Method) is a classical method in recreational benefits evaluation of natural resources. Existing TCM models include three categories: ZTCM（Zonal TCM）, ITCM（Individual TCM）and AITCM(Advanced ITCM). The three types of models have different precondition requirements that depend on different situations of tourism destinations. In Jiuzhaigou Nature Reserve, it is found that all of the existing TCM models are unsuitable to be used for the benefits evaluation since the Jiuzhaigou's situation doesn't meet the required pre-assumptions. The authors build a new analytical method named TCIA (Travel Cost Interval Analysis). Using the new method, the recreational benefits of natural resources in Jiuzhaigou nature reserve in 2000 is evaluated, which is RMB 10.85 billion yuan.

摘要： 旅行费用法TCM常用于评估旅游地的游憩价值，现有的TCM模型大致可分为3类：分区旅行费用法（ZTCM）、一般个人旅行费用法（ITCM）和高级个人旅行费用法（AITCM）。这3类模型各有特点，适用范围有所不同。针对九寨沟这类旅游地，上述3类模型的理论假设与旅游地的实际情况不相符，因而都不适用。作者提出了一种改进的旅行费用分析方法——旅行费用区间分析(TCIA)，并用该方法评估了九寨沟2000年的自然资源游憩价值，结果为10.85亿元人民币。
