农作物秸秆利用的影响因素分析及其效果评价

Analysis of the Influencing Factors and Evaluation of Effect of Crop Stalk Utilization

【目的】以呼图壁县为研究区域,对农作物秸秆利用影响因素进行分析,结合不同的秸秆还田方式(直接还田、过腹还田和草木灰还田等)对土地利用潜力的影响,为提高当地秸秆利用率和土地利用潜力提出措施和建议。【方法】采用层次分析法。【结果】农作物秸秆的可收集利用量、牲畜饲养量、技术指导、政策支持、农业机械化程度、农作物秸秆产量、耕地面积、劳动力等影响因素都直接影响到秸秆资源的利用。【结论】不同的农作物秸秆还田方式效果不同,充分利用好农业生物质能,提高土地利用潜力,为土地资源的节约集约利用发挥作用。

【Objective】Analyze the crops straw utilization factors,combined with the impacts on land usepotential by different ways of straw returned in Hutubi county,put forward measures and Suggestions in order to improve the local straw utilization and potential land use.【Method】Analytic hierarchy process was used in the research and Hutubi County was taken as the study area.【Result】The total collection of crop stalks, livestock population,technical guidance,policy support,the degree of agricultural mechanization,crop stalk production,arable land,labour and other factors all directly affected the stalk resources.【Conclusion】Effects of different methods of returning crop stalks into fields vary,and making full use of agricultural biomass can increase production and farmers' income. Meanwhile,improving the land utilization potential plays a role in economical benefits and intensive utilization of land resources.
