生物质原料供应链技术经济研究进展

生物质原料供应链是生物质资源转化的基础保障，是未来实现大规模生物质能源开发利用的关键所在。本文对生物质供应链相关技术问题进行了分析，分别介绍了生物质原料收获与收集、储存与预处理、运输等技术现状与存在的问题。同时，对供应链的技术经济性进行了综述，对比阐述了国内外采用的研究方法，通过建立定量化的数学模型来优化供应链的技术经济指标是当前研究的主要方式。国内外研究结果显示，生物质原料的收购价格、收集半径和收购模式是影响生物质供应链成本的关键因素。我国由于户均耕地占有面积小，生物质原料分散，生物质供应链是一个复杂的系统工程。在此基础上，进一步对生物质供应链的发展提出了展望，为生物质资源供应链的研究与发展提供参考和借鉴。

Advance on technical and economic analysis of the biomass supply chain

Biomass supply chain is the basic guarantee of the conversion of bioresource, and is also the key to the large-scale utilization of bioenergy in the future. In this paper, related technical problems were firstly analyzed, and the status and existing problems of biomass raw materials harvest and collection, storage and pretreatment and transportation were introduced, respectively. Meanwhile, the tech-economic of the supply chain of biomass was summarized, and the research methods adopted in China and abroad were compared and expounded. The main research areas are to optimize the technical and economic indicators of the supply chain by developing quantitative mathematical models. The research results showed that the purchasing price, collection radius and collective mode of biomass were the key factors influencing the cost of the biomass supply chain. In China, the biomass supply chain is a complex system because of the small sizes of household cultivated land and the dispersal of biomass. On the basis, the prospect of the development of the biomass supply chain was proposed, which can provide a reference for the research and development of the biomass supply chain.
