摘 要 ：随着一次能源的逐渐枯竭，可再生能源的开发利用日益引起人们的关注。本文以江苏省盐城市秸秆资源现状为切入点，分析了生物质秸秆发电的社会经济背景。在分析秸秆发电技术设备条件的基础上，运用成本收入法验证了秸秆发电的经济效益可行性，结果表明：若充分利用可利用的生物质秸秆资源，每年可带来约3.7亿元的收入。借鉴前人已有研究成果，经统计推理可知秸秆发电大大降低了CO₂、SO₂、烟尘等污染物的排放，进而说明秸秆发电的生态效益非常可观，利用前景广阔。同时论述了秸秆发电良好的社会外部性，得出3点社会效用。并针对盐城市进行秸秆发电所存在的问题提出了相应对策。

Abstract:With gradual depletion of non-renewable energy resources, people now turn their attention to renewable energy resources. This paper introduces straw resources in Yancheng and analyzes the social economic background of electricity generation from straw. Then it analyzes the technology and equipment conditions for electricity generation from straw based on a number of materials and empirical research. Income-cost analysis method is used to verify economic benefit feasibility of the technology. Results show that the full use of available straw can generate about 0.37 billion yuan per year. Based on previous studies, it is deduced that generation of electricity from straw can reduce CO₂ and SO₂ emission and dust pollution. Therefore straw is a clean resource and electricity generation from straw has strong ecological benefits. Furthermore, there are good external social benefits of electricity generation from straw. Finally, appropriate measures are proposed to redress problems of generating electricity from straws in Yancheng.
