吉林省主要农作物秸秆资源评价及能源化利用分析

Analysis on Evaluation and Energy Utilization of Main Crop Stalk Resource in Jilin Province

摘要:

从吉林省农作物秸秆生产与利用现状入手,针对吉林省秸秆能源化利用中存在的问题及发展状况,对吉林省农作物秸秆资源量进行了定量评价。结果表明,2008年吉林省主要农作物秸秆实物资源量为4 038.89万t,其中,可能源化利用的秸秆量达3 101.99万t,折合标准煤1 622.58万t;单位土地面积可能源化利用的秸秆量为7.97 t/hm²,其中:松原10.43 t/hm²、四平9.15 t/hm²、白城8.47 t/hm²、长春8.16 t/hm²;这些地区具有秸秆能源化利用的资源优势。在此基础上,指出吉林省秸秆能源化利用的产业化发展政策建议。

Abstract:

Starting from current situation of production and utilization of crop straw in Jilin Province,and according to problems in utilization of straw for energy,crop straw resources in Jilin Province was evaluated quantitatively.The results showed that resource of straw was 40388900 t in 2008 in Jilin Province,in which 31.0199 million tons can be used for energy and this equal to 16225800 t of coal.Capacity of straw which can be used for energy was 7.97 t/hm² on average,of which Songyuan was 10.43 t/hm²,Siping 9.15 t/hm²,Baicheng 8.47 t/hm²,Changchun 8.16 t/hm².Straw utilization for energy in these areas had advantages of resources.On this basis,policy recommendations on industrial development of energy utilization of straw in Jilin Province were put forward.
