文章首先论述了资源替代的基本原理,即同种资源具有多种用途,可将其使用领域划分为重要领域、次要领域与一般领域;同时,同种需求可由不同的资源来满足。此外,资源的多用途性及满足同种用途资源多样化的特点,使相关资源之间在用途上存在共同的应用领域及独立应用领域,具体可将其分成资源的通用领域、共用领域和专用领域三种状况。在此基础上,进行资源产出分析:单一投入单一产出分析、单一投入多种产出分析、多种投入多种产出分析和多投入单产出分析。基于上述研究,文章重点进行了资源之间的替代分析,即同资源多领域应用分析和同领域不同资源替代分析,为充分利用资源,保护生态环境,实现资源循环利用的可持续发展提供了思路。
The article first discusses the basic principle of resource replacement, that is, the same resource has multiple purposes and can be divided into important areas of its use, secondary areas and general areas; the same kind of demand can be met by different resources. In addition, the multipurpose nature of resources and the diversification of resources for the same use provide common applications and independent applications in the use of related resources, which can be divided into common fields, common fields and specializations of resources Three areas of the situation. On this basis, resource output analysis: a single input single output analysis, a single input multiple output analysis, multiple input multiple output analysis and multiple input single output analysis. Based on the above research, the article focuses on the alternative analysis of resources, that is, the analysis and application of resources in different fields and the alternative analysis of different resources in the same area, providing ideas for making full use of resources, protecting the ecological environment and realizing the sustainable development of resource recycling. .
