利用《中国统计年鉴》2002-2011年的统计资料和数据,筛选出合适的秸秆系数,对全国主要农作物秸秆生物质资源的蕴藏量进行定量测算,并对其时空分布利用模式进行研究,旨在为促进秸秆资源的综合利用与相关行业部门提供参考。结果表明:1全国农作物秸秆总蕴藏量从2002年的59 886×10~4t增加到2011年的74 153×10~4t,年均增加2.38%;2同年度4类秸秆产量分别呈现稻草>玉米桔>麦秸>豆秸趋势;32011年全国秸秆总蕴藏量中,稻草27%、麦秸19%、玉米桔27%、甘蔗桔7%、油菜桔5%、豆秸4%、棉柴3%、花生桔2%、其他秸秆6%;中南29%、华东24%、东北16%、西南12%、华北11%、西北8%。4秸秆养畜、秸秆还田和秸秆能源化是秸秆综合利用的主要3大模式。
Based on the statistical data and data of China Statistical Yearbook 2002-2011, the appropriate straw coefficients were screened, the reserves of biomass resources of main crop straw in the country were quantitatively calculated, and the patterns of temporal and spatial distribution were studied, aiming at To promote the comprehensive utilization of straw resources and related sectors to provide reference. The results showed that: 1 The total amount of crop stalks in the whole country increased from 59 886 × 10 4 t in 2002 to 74 153 × 10 4 t in 2011, with an annual increase of 2.38%. In the same year, the yield of four kinds of stalks showed straw> corn Orange> straw> soybean straw. In the total amount of straw in 32011, 27% of straw, 19% of straw, 27% of corn, 7% of sugarcane, 5% of rapeseed, 4% of soybean straw, 3% of cottonwood, Peanut tangerine 2%, other straw 6%; South 29%, East China 24%, Northeast 16%, Southwest 12%, North China 11%, Northwest 8%. 4 straw livestock, straw and straw energy is the main three comprehensive utilization of straw.
