中国农作物秸秆资源产量分布及利用分析
Analysis of yield distribution and utilization of crop straw resources in China
摘要
Abstract
As a big agricultural country,China has abundant crop straw resources.Based on official statistical data and literature research,this study analyzed the yield change,regional distribution and resource utilization of straw resources in China during 2011-2022,aiming to provide scientific basis for rational utilization of straw resources.The results showed that during the 11 years from 2011 to 2022,the straw yield in China increased from 752.53 million tons to 864.29 million tons,with an average annual growth rate of 1.35%,among which the corn straw yield was the highest.In 2022,the straw production was mainly concentrated in East China,Central China and Northeast China.The straw production in East China was the highest,with 194.39 million tons,accounting for 22.49%of the total straw resources in the country.South China was the least,(66.88 million tons)accounting for only 7.74%of the total straw resources.From the perspective of provincial distribution,the total output of straw in Heilongjiang Province was the highest,which was 85.44 million tons,accounting for 9.89%of the total output of straw in China.The straw yield per unit area was the top three in South China,Central China and East China,which were 11.79,10.09 t·hm-2 and 9.17 t·hm-2 respectively,higher than the national average yield of 6.77 t·hm-2.The lowest straw yield per unit area was 4.29 t·hm-2 in northwest region.Since 2020,China's straw collection utilization has stabilized at about 723.00 million tons,and the comprehensive utilization rate of straw has reached 87.70%-88.10%,of which fertilizer utilization was mainly used,and the utilization rate was more than 60%,and the utilization rate of feed,fuel,base material and raw material was basically decreasing year by year,and the development rate of high-value utilization was slow.To sum up,China's crop straw resources have a huge output,with a large-scale comprehensive utilization of raw materials,low value-added utilization accounts for a relatively large proportion,and high value utilization needs to be improved.Therefore,it is urgent to strengthen government guidance,agricultural technology promotion and scientific research and innovation,in order to achieve sustainable agricultural development and efficient recycling of straw resources,and help green agricultural development and build a resource-saving society.关键词
