to encourage group travel to the uk, the government is now suggesting the introduction of a specific tourist visa, which could be time-limited and competitively priced.

based on tcm, the authors present a new method named group travel cost interval analysis method so as to evaluate the recreational value of nature reserves more reasonably and truly.

根据秦岭北坡森林公园为陕西省森林生态旅游活动的主体，而森林公园游憩价值又是非市场性的，这就需要探索新的方法来进行计量测评。
