黑龙江省农作物秸秆资源利用现状及中长期展望

Utilization status and medium and long-term forecast of crop straw in Heilongjiang Province

黑龙江省农作物秸秆资源丰富,但各地区分布差异大。该文通过对黑龙江省农作物秸秆资源全面调查,研究了各地区的秸秆资源量及利用现状,并根据经济社会发展趋势对农作物秸秆资源量以及利用途径进行了中长期预测。结果表明,2007年黑龙江省农作物秸秆主要分布在哈尔滨、绥化、齐齐哈尔和佳木斯,占全省的73.8%,秸秆利用主要以家庭燃用为主。扣除家庭燃用、秸秆还田以及养畜等用途外,预测到2015年黑龙江省剩余秸秆资源量为315万t,2020年为511万t,并根据预测结果将黑龙江分为3个类型区,建议对各区采取不同的利用技术。

Though crop straw resource in Heilongjiang Province was very abundant, distribution of crop straw was different. So in this study, the crop straw resource of Heilongjiang province was detailed surveyed, the crop straw resource and utilization status was obtained and medium and long-term forecast was achieved according to the economic development status The results showed that main crop straw resource was mainly distributed in the main grain production area, such as Harbin, Suihua and Qiqihar in Heilongjiang province, accounting for 73.8% in the whole province.
