| 摘要: |
| 农作物秸秆作为重要的非粮生物质原料，其大规模的能源化利用将会产生巨大的经济效益、环境效益及社会效益。但在其进行产业化利用之前，对生产成本进行分析是保证其经济可行性的必要过程。本研究以河南天冠集团小麦秸秆收集实践为基础，首先建立关于收集、运输、装卸、预处理和储存过程的模型并进行成本分析；然后对影响秸秆收储运成本的因素进行蒙特卡洛模拟分析，以期为降低其生产成本提供科学依据。结果表明：人工散秆的收储运总成本最高，为298元/t，其次为人工打包、机械散秆、机械打包，总成本分别为265、252和222元/t。用蒙特卡洛分析法对影响总成本的部分因素模拟分析结果显示：田间人工工资和人工捡拾速率对总成本的影响达显著水平，而收获速率和可持续移走量对4种模式收储运总成本的影响差异不显著。 |

| Abstract: |
| Crop residue will bring a remarkable economical,environmental and social benefits when they are utilized industrially as an important non-food biomass feedstock in large-scale.However,prior to industrial utilization,it is necessary to analyze the cost of production in order to ensure the economic viability.This present study discussed the economics of the wheat residue logistic system including collection,storage,transportation based on the field practices of Henan Tianguan enterprise group.In order to provide scientific guide to reduce the production cost,the factors which influence total cost of wheat residue logistic chain was analyzed using Monte Carlo method.The results showed that,in descending order,the highest total cost of the four investigated wheat residue supply patterns is from manual scattered mode,manual baled mode,mechanical scattered mode,mechanical baled mode,with the cost of 298,265,252,222 CNY/t,respectively.Monte Carlo simulation results showed that the influence of farmer labor price and manual collection rate on the total cost have reached significant level;whereas the effect of harvest rate and sustainable removable yield on the total cost did not show significant difference. |
