吉林省是我国玉米主产区,玉米秸秆资源丰富。通过实地调查和文献分析,选择玉米秸秆不同的评价指标,对其进行了评价分析。结果表明:2008年吉林省玉米秸秆可利用资源量为2 639.76万t,空间分布呈现“两高一低”的特征,即中西部高和东部低。依据玉米秸秆空间分布特点,该文将吉林省分为秸秆资源富集区、一般区、较少区,并提出了相应的开发利用技术和产业发展方向。
Jilin Province is the main corn producing area in China with abundant corn stalks. Through field survey and literature analysis, the different evaluation indexes of corn stalks were selected and evaluated. The results showed that the available resources of corn stalks in Jilin Province in 2006 were 26.3976 million tons, and their spatial distribution showed the characteristics of “two high and one low”, that is, high in the central and western parts and low in the eastern part. According to the spatial distribution characteristics of corn stalks, this paper divides Jilin Province into straw-resource-rich areas, general areas and less areas, and puts forward corresponding development and utilization technologies and industrial development directions.
