本文简介了资源物理学及其拓广，提出了所有自然资源都可以用度量，给出了评价自然资源消耗的生态价值系数表达式和过程分析法，借助它可以优化资源的利用。

Resource physics is briefly introduced in this paper. By prolonging resource physics which is based on entropy theory,and introducing the exergy concept, a new idea that natural resources can be measured by exergy is set up. The formula of the ecological cost coefficient of natural resources consumption and the process analysis method are also put forward. By this means resource utilization can be optimized. Finally, an example of the analysis of accumulated exergy in the process of chlor-alkali production is given.
