摘要
我国秸秆总产量居世界首位。根据已有秸秆总量计算中存在的不足,利用相关统计数据以及实地调查结果对我国秸秆总产量重新进行了计算,并就近年来我国秸秆总产量的变动和主要农作物秸秆数量进行了分析。同时,还根据我国主要农作物的地域分异规律,把我国秸秆资源分布及其分区开发利用研究划分为东北区、长江中下游区等8大区,并以此为基础,对我国秸秆总产量以及单位产量的区域分布、几种主要农作物秸秆的区域分布进行了分析和描述。
The total yield of straw in China rank the first place in the world. According to the existent insufficiency of gained straw total yield, the paper recalculated the straw total yield of China using relative statistical data and field investigation result, and analysis changes of straw total yield in recent years and the major crops straw quantity. Based on the regional differentiation regularity of major crops in China, the author divided the straw pruduction areas into eight regions such as northeast region and middle and lower Yangtze region etc. and discussed the regional distribution of straw toatal yield, unit yield and major crops straw.
