摘要:

秸秆还田作为目前秸秆资源化利用的主要方式之一，它有增加土壤有机质、改善土壤质量、提升作物产量等作用，同时还有保护生态环境、减少农业面源污染等功效。但秸秆还田所带来的成本增加，在某种程度上影响了农户秸秆还田的积极性，因此，给予农户一定补贴等激励措施势在必行。文章以玉米秸秆还田为例，基于河北、山东两省的农户调查数据，分析两个地区农户玉米秸秆的利用状况，在此基础上研究农户秸秆直接还田受偿意愿的影响因素。结果表明，农户受访者年龄、秸秆还田是否增加成本、秸秆还田增加的费用是否由政府承担、秸秆焚烧查处力度是否强、与秸秆不还田相比秸秆还田增加的费用这5个因素对农户秸秆还田受偿意愿有着显著的正向影响，而受访者是否是村干部和秸秆还田是否改善土壤质量这两个因素对农户秸秆还田受偿意愿有着显著的负向影响。
