认为乔光华等的研究在推断游憩需求曲线时存在方法上的问题，直接将旅行成本和时间价值作为游憩价值不符合旅行成本法的基本原理和公共物品无（或低）市场价格的经济理论。
Inferred the demand curve of recreation . They calculated directly the travel cost and value of time as the value of recreational function . This approach is not accord with the basic principle of TCM and the economic theory of public goods without ( lower ) marketed price .
