This paper criticizes some theories about value of natural resources, explains the value of forest resources with Marx's labor axiology,thinks that the value is determined by the labor-time in socially necessary on utilized the worst woodland which based social wants in process of reproduction of forest resources,not by the total price of various use value.It puts forward that the value of a use value of forest resources is a compensation of stated value of forest resources on this use value,and its compens...

该文批判了西方有关自然资源的效用论、地租论和传统马克思主义经济学中的无价论、实用论，运用马克思劳动价值论解释森林资源的价值，认为其价值量决定是由森林资源再生产中已利用的最差等级林地的以社会需要为基础的社会必要劳动时间决定的，而不是森林各种使用价值的加总，各种使用价值的价值量是一定的森林资源价值量在该使用价值上的分摊量，其价值补偿是成本补偿而不是效益补偿。
