摘　　要：秸杆是全球第一大可再生资源,我国拥有量居世界首位.由于未高效合理利用,不仅浪费了可利用的宝贵资源,对生态环境也产生了不良的影响.从秸杆资源化利用角度,构建循环利用效益评价指标体系,运用模糊综合评价模型对秸杆作饲料、肥料、沼气、气化、发电、建材的经济效益、生态效益和社会效益进行评价,提出了优化利用方案,以期推动我国秸杆资源合理利用的进程.The straws are the biggest recycling resource in the world, and our country boasts the largest number around the world. Due to irrational use, the precious recycling resource not only is wasted, and also affects the eeo-environment when it is burned. This thesis has evaluated the economic efficiency, the ecological efficiency and the social efficiency of using straws as feed, fertilizer, gas, gasification, power generation, building materials from the point of using straws as a resource. Moreover, the thesis also put forward the program of optimizing the use, in order to motivate the progress of using the crop straws in a rational way in our country.
