吉林省主要农作物秸秆可利用资源分析评价

通过实地调查和文献分析,选择不同的秸秆资源评价指标,对吉林省主要农作物秸秆资源进行了调查和评价。结果表明:2008年吉林省玉米、水稻、大豆3种主要农作物秸秆的可利用资源量为3 113.37万t,秸秆总量表现为"一高两低",即玉米比重大,水稻和大豆比重小;空间分布呈现"两高一低"的特征,即中西部高,东部低。依据吉林省秸秆资源空间分布特点将吉林省秸秆资源划分为富集区、相对富集区、一般区、贫乏区,针对不同地区提出了相应的开发利用发展方向。

Analysis and Evaluation of Utilizable Resources of Main Crop Straw in Jilin Province

Based on data analysis and field survey, the study chooses various evaluating indices to finish the research and evaluation on main crop straw in Jilin province. The results showed that the amount of utilizableresources of main crop straw of corn，rice and soybean amounted to 31133　7million tons in Jilin province in 2008 and the resources were characteristic of being “one high, two low”, that is, a higher proportion of corn and a low proportion of rice and soybean; spatial distribution was characteristic of “two high and one low”, th
at is, “high in central and western regions, low in eastern region”. According to resource distributing characteristics in each region, the whole province was divided into rich region, relatively rich region, moderate region and poor region. The paper put forward the corresponding directions of development and utilization according to different regions.
