摘要
为提高长三角地区秸秆资源的综合利用率,采用草谷比法,评估长三角地区秸秆的资源量和秸秆资源的分布特点。结果表明:2000-2014年长三角地区农作物秸秆资源总量呈稳中上升趋势;秸秆分布地区格局差异显著;作物秸秆产量主要分布在粮食主产区的江苏省和安徽省,浙江省和上海市则比较低,2000-2014年作物秸秆资源量为江苏>安徽>浙江>上海;农作物秸秆主要类型为稻谷、小麦和油菜籽,以稻谷为长三角地区最主要的粮食作物秸秆。
To estimate the crop straw resources in Yangtze River Delta area, and promote the integrated utilization, the ratio of main products to by-products was employed to evaluate the straw resources amount and the distribution in Yangtze River Delta area. Results： The crop straw resources amount in Yangtze River Delta area showed a stable increasing trend with significant spatial variation during 2000-2014; The crop straw resources mainly distributed in Jiangsu Province and Anhui Province, which were the major grain producing areas, followed by Zhejiang Province and Shanghai City. The sequence was Jiangsu Province〉Anhui Province〉Zhejiang Province 〉 Shanghai City; The main straw types were rice straw, wheat straw and rape straw, in which rice straw was the major grain crop straw in Yangtze River Delta area.
