针对生物质发电中秸秆收集困难的问题,对秸秆供应构建4种模式:人工收集主动运送模式、机械收集主动运送模式、人工收集等待收购模式和机械收集等待收购模式,建立农户秸秆供应成本模型,计算不同模式的成本,并对不同的重要因素进行单因素敏感性分析.结果表明:人工收集模式比机械收集模式成本低,但受人力工资影响大,当人力工资≥18元/h时,人工收集主动运送模式成本最高;当土地面积>0.667hm2时所有模式的成本稳定,变化不大;运输距离对人工收集模式成本的影响大于机械收集模式,留茬高度越低影响越大;作物产量水平越高,越适合机械收集模式.
In order to solve the problem of difficult straw collection in biomass power generation, four models of straw supply were constructed: active collection mode of artificial collection, active collection mode of mechanical collection, waiting and acquisition model of artificial collection and waiting and acquisition mode of mechanical collection, The cost of different models was calculated and the single factor sensitivity analysis of different important factors was carried out.The results showed that the cost of manual collection mode was lower than that of mechanical collection mode but was greatly affected by human salary, The cost of collecting active transport mode is the highest; the cost of all modes is stable with little change when the land area is> 0.667hm2; the impact of transport distance on the cost of manual collection mode is greater than that of mechanical collection mode; the impact of stubble height is lower; The higher, the more suitable for mechanical collection mode.
