我国造纸用农业秸秆资源现状

The Status of Agricultural Residues Resources Available for China's Paper Industry

本文在收集分析了大量有关秸秆资源估算资料的基础上,根据我国造纸企业的秸秆实际收集状况,对文献中的秸秆可收集系数进行了修正.得到适合于造纸工业需要的、可收集到的纤维秸秆资源量为（3.0～3.3）亿t.其中约1亿t为稻草,近1亿t为玉米秸秆,而这两种秸秆在目前造纸工业中尚没有大量使用.对于造纸工业来说,最关注的是造纸企业每年实际可以收集到多少可用于造纸生产的秸秆,以便根据我国的秸秆实际得到资源量,估算秸秆制浆的规模、产地布局等.

Based on the analysis of relevant data of agricultural residues resource,combining the particle collection situation in the paper mills,the author suggested to revise the collectable coefficient of agricultural residues which has been cited in the literatures,the collectable agricultural residues which can be used for paper industry was estimated 300 ～ 330 million tons totally,the amounts of rice straw and corn stalk which have not been widely used are equivalency about 100 million tons.It was pointed out that available amount of agricultural residues resource is the basis of the scale and location of the pulp mills.
