| 摘要: |
| 根据区域特点和工程类型提出秸秆能源化工程原料运输半径,对推进工程的应用、原料稳定供应、提高经济收益以及改善生态环境具有重要意义.以秸秆能源化工程原料运输半径为核心,提出秸秆能源转化密度、工程经济和环境效益评价模型,评价指标包括单位经济效益、温室气体和PM2.5减排潜能.对哈尔滨地区发展秸秆能源化工程的运输半径进行了经济和环境评价,结果表明：哈尔滨地区是黑龙江省发展秸秆能源化工程的优势区域,在发展秸秆沼气、乙醇、热电联产和成型燃料工程时,经济效益最优原料运输半径分别为37、35、22和4 km；此时,4类能源化工程的环境效益从高到低依次为秸秆沼气、乙醇、热电联产和成型燃料工程. |

| Abstract: |
| The concept of material transportation radius for straw-energy engineering, proposed in line with the regional characteristics and project types, is of great significance in promoting engineering economic efficiency and ecological environmental protection. Taking the concept as the core, straw energy conversion density and the evaluation model for engineering economy and environmental efficiency have been put forward, with the evaluation indicators including economic units and the reduction potentials in the emission of greenhouse gases and PM 2.5. An economic and environmental evaluation of the straw transportation radius in Harbin region has fully demonstrated that Harbin, the most advantageous region in Heilongjiang Province in developing straw-energy engineering, embraces the economically optimized straw transportation radiuses of 37, 5,2 km, and 4 km respectively for the development of straw-gasification, -ethanol, -based heat and power cogeneration and -briquetting production projects. Meanwhile, in view of environmental benefits, the descending order of the 4 types of energy engineering are straw-gasification, -ethanol, -based heat and power cogeneration and -briquetting production projects. |
