Assessment on the Recreational Value of the Longevity Resources along Bama Panyang River in Guangxi: Based on the revised Zonal Travel Cost Method
广西巴马盘阳河沿岸长寿资源的游憩价值评价——基于修正的区域旅行费用法

The recreational value of the bank along Bama Panyang River in Guangxi was estimated in this paper by applying the revised Zonal Travel Cost Method(ZTCM).ZTCM is to establish functional relation between the number of tourists in a region and their average travel cost.When calculating the recreational demand function,we should take the following points into consideration:1)How to partition the travel zones;2)How to calculate the travel costs when tourists travel to multi-sites;3)How to calculate the travel costs(mainly opportunity cost)when tourists stay at a destination for a long time.As for this paper,its contributions can be divided into two aspects:1)Cost interval partition based on direct cost and traveling days acquired from the sample survey results can avoid the average travel cost deviation brought by geographical zoning method;as to those who stay over 30 days,opportunity cost is estimated by the tourists’average board and lodging cost instead of the average wage,which can avoid the opportunity cost calculation deviation caused by the tourists’lingering for long time in a destination;caculating the recreational cost of tourists who specially visit Bama for sightseeing or leisure alone can overcome the difficulty of overestimating the recreational value of a destination;2)The evaluation results based on Logarithmic Function Model show that recreational value of Bama Area was at least 1.854 billion RMB in 2009;at the same time,according to the estimation model of consumer’s surplus and the correlation analysis between their travel cost,travelling days and their ages,we can infer that the established function model accords with the current reality of tourists in Bama,and the economic value of the longevity resources in Bama is much more fit for developing the leisure tourism industry.Therefore,it can be concluded that the longevity resources in Bama are worthy of special protection and restrictive development.
