摘  要：
基于统计数据和农户调研数据,估算了西部七省区农作物秸秆资源量、秸秆资源密度、人均占有秸秆数量和秸秆养分资源量,分析了秸秆资源量变化趋势(1997—2011年)及资源分布利用现状,讨论了制约秸秆综合利用的因素和提高秸秆利用率的途径.结果表明:2009年西部七省区农作物秸秆资源理论数量达到8.82×107t,谷物类秸秆占总量的63.1%;秸秆养分还田总量达1.20×106t,还田率达50.5%.西部七省区秸秆资源密度低于全国平均水平,人均秸秆占有量略高于全国平均水平.秸秆资源主要用作燃料、饲料、工业原料、基质和直接还田,分别占资源总量的33.8%、29.3%、5.2%、1.8%和13.5%,焚烧和废弃的秸秆分别占秸秆资源的11.1%和5.3%.

摘  要：
Based on agricultural statistical and investigating data on farmers,amount,distribution density and amount per capita of crop straw resources of seven western provinces of China were estimated,the trends of amount dynamics from 1997 to 2011 and distribution and utilization of crop straw resources were analyzed,and the constraints of comprehensive utilizing straw resources and possible ways to improve straw utilization were discussed. Results showed that theoretical amount of crop straw resources in seven western provinces was 8. 82 × 107t in 2009,in which straw of cereals accounted for 63. 1% of the total,and straw nutrients returned back to fields was 1. 20 × 106t, accounting for 50. 5 % of the total. The distribution density of straw resources of the seven western provinces was less than the national mean,while the amount per capita of straw resources was higher. According to the survey,the straw was mainly used as fuel,feed,industrial materials,matrix and returned field directly,accounting for 33. 8 %,29. 3 %,5. 2 %,1. 8 % and 13. 5 % of the total amount,respectively. In addition,the amounts of straw burned and abandoned were 11. 1 % and 5. 3 % of the total,respectively.
