摘要:我国每年约产生秸秆7亿吨。受消费观念和生活方式的影响,农村秸秆资源完全处于高消耗、高污染、低产出的状况,相当多的农作物秸秆被弃置或者进行焚烧,没有得到合理开发利用。焚烧秸秆不仅浪费资源、污染环境,而且影响群众健康和公共安全,成为一个尚待解决的社会性问题。本论文通过对现在秸秆国内外主要的处置方法着手,分别从秸秆资源化、能源化和工业原料化的途径进行分析,以达到提出废弃物资源的合理分配和利用的方式,形成一种多途径的综合利用方式,使未被利用的农田资源得到良好的配置,从而使秸秆尽量达到资源化,高效化,产业化,既能产生经济效益,又能产生社会效益,同时又保护生态环境并改善我国能源结构和我国能源安全,减少环境污染,在改善农村环境质量,实现农田废弃物的资源化利用,社会持续发展中发挥积极作用,在提高城乡居民生活水平和质量,对于我国建设节约型社会,发展循环经济,给农田废弃物的利用方式提供了参考,对实现经济社会可持续发展具有重要意义,为节约型社会和资源的合理利用作出贡献。6336

Resourcing Utilization of Crop Straw
Abstract About 700 million tons of straw a year in China.Under the influence of consumer attitudes and lifestyles, rural straw fully in high consumption, high pollution and low output state, quite a lot of crops straw were dumped or burned, no reasonable development and utilization.Burning straw is not only a waste of resources, environmental pollution, but also affected the public health and public safety, becoming an outstanding social issues.This through on now straw both at home and abroad main of disposal method to, respectively from straw resources of, and energy of and industrial raw materials of of way for analysis, to reached made waste resources of reasonable distribution and using of way, formed a more way of utilization way, make is not is using of farmland resources are good of configuration, to make straw as reached resources of, efficient of, industrialization, both can produced economic benefits, and can produced social benefits, While and protection ecological environment and improve in China energy structure and in China energy security, reduced environmental pollution, in improve rural environment quality, implementation farmland waste of resources of using, social continued development in the play actively role, in improve urban and rural residents living and quality, for in China construction saving social, development cycle economic, to farmland waste of using way provides has reference, on implementation economic social sustainable development has important significance, for saving social and resources of reasonable using made contribution.
