摘要
基于官方统计数据和文献资料调研,对云南省16个州(市)2021年的主要农作物(玉米、水稻、小麦、薯类、油料和豆类)秸秆资源进行调查,通过草谷比系数法估算农作物秸秆的理论资源量,利用标煤系数法对农作物秸秆进行能源化潜力评估.结果表明,2021年云南省农作物秸秆资源总量、理论资源量和可收集资源总量分别为1 937.01、1 811.63万t和1 731.77万t,可能源化利用资源总量为166.6万t,评估生物质能源潜力量为84万t标准煤.云南省农作物秸秆资源量较大,可能源化利用农作物秸秆资源量偏低.
Abstract
Based on official statistical data and literature research,the straw resources of major crops(maize,rice,wheat,potato,oil and beans)in 2021 in 16 prefectures(cities)of Yunnan Province were investigated.The theoretical resources of crop straw were estimated by grass-grain ratio coefficient method,and the energy con-version potential of crop straw was assessed by standard coal coefficient method.The results showed that in 2021,the total crop straw resources,the theoretical resources and the total recoverable resources in Yunnan Province were 19.370 1,18.116 million tons and 17.317 million tons,respectively.The total energy utilizable resources was 1.666 million tons,and the estimated biomass energy potential was 840 000 tons of standard coal.The amount of crops straw resources in Yunnan Province is large,but the amount of crop straw resources that can be utilized for energy is low.
