【摘要】：中国是农业生产大国,秸秆资源较为丰富,开发利用农作物秸秆资源、发展生物质能源具有重大的经济和生态效益。因此,科学评估中国秸秆资源能源化利用的潜力及其在不同地区的布局尤为重要。本文利用各省农业生产数据测算了全国各省大田作物田间秸秆产量和可利用秸秆资源数量,在此基础上利用土地遥感数据和GLO-PEM模型,测算了1km×1km栅格尺度的秸秆资源分布密度并评估了秸秆能源企业在各地区布局的适宜性。相比之前的研究,本研究考虑了秸秆资源在不同区域的分布密度差异,这对于计算秸秆这类收集和运输成本较高的资源的可利用率具有重要意义。此外,本文也通过2014年和2010年的对比,分析中国秸秆资源分布密度和能源企业适宜布局的变化趋势。研究结果表明:2014年中国主要大田作物秸秆资源总量为8.97亿t,可收集资源量为7.69亿t,可能源化利用秸秆资源总量为1.86亿t,吉林、江苏、河南、安徽、黑龙江等省份适宜建立大型秸秆能源企业,且未来秸秆能源布局也将向这些地区集中。东北、华北、长江中下游地区、成都平原、西南以及新疆等少部分地区适宜建立小型秸秆能源企业。
[Abstract]:China is a large agricultural country with abundant straw resources. Developing and utilizing crop straw resources and developing biomass energy have great economic and ecological benefits. Therefore, it is very important to evaluate the potential of energy utilization of straw resources in China and its distribution in different regions. In this paper, the field straw yield and the amount of available straw resources of field crops in various provinces of China were calculated by using the agricultural production data of each province. Based on this, land remote sensing data and GLO-PEM model were used. The distribution density of straw resources on 1km 脳 1km grid scale was calculated and the suitability of straw energy enterprises in different regions was evaluated. Compared with previous studies, this study considered the distribution density difference of straw resources in different regions, which is of great significance to calculate the utilization ratio of straw resources with high collection and transportation costs. In addition, through the comparison between 2014 and 2010, this paper analyzes the distribution density of straw resources and the trend of the suitable distribution of energy enterprises in China. The results show that in 2014, the total amount of straw resources of main field crops in China is 897 million tons, the amount of collectable resources is 769 million tons, the total amount of straw resources of possible source utilization is 186 million t, Jilin, Jiangsu, Henan, Anhui, Jilin, Jiangsu, Henan, Anhui, Heilongjiang and other provinces are suitable for the establishment of large straw energy enterprises, and the future straw energy distribution will be concentrated in these areas. Northeast, North China, middle and lower reaches of the Yangtze River, Chengdu Plain, Southwest and Xinjiang are suitable for establishing small straw energy enterprises.
