摘要:
由于作物秸秆类型不同,其营养成分和利用价值不同,因此目前仅根据草谷比系数法以重量形态衡量其利用潜力,难以全面直接反映秸秆资源多种利用价值,因此本文基于重量、能量和谷物当量三种形态定量估算中国不同利用方式下作物秸秆资源的适宜利用潜力。本文在基础年鉴数据和前人研究成果的基础上,经研究其主要结论如下:2001至2014年中国作物秸秆资源总量整体上升,至2014年中国作物秸秆肥料化、基料化和原料化的利用潜力为6.77×1011Kg;能源化的利用潜力为8.74×1018J;适宜饲料化的作物秸秆资源利用潜力为6.13 ×1011 Kg谷物当量;数据显示,以重量、能量和谷物当量三种形态综合核算中国秸秆资源的计量结果较为一致,但能量和谷物当量形态更能直接体现秸秆资源能源化和饲料化的实际利用价值,计算过程和核算结果科学有效;同时通过空间自相关定量分析出中国各地秸秆资源量在空间上呈现出显著的地域边缘属性,整体而言,东部和北部地区秸秆资源利用潜力高于西部和南部地区。

Analysis of Temporal and Spatial Characteristics of Suitability Utilization potential Evaluation on Crop Straw Resource in China

Abstract:
China is rich in crop straw resource, the comprehensive utilization of straw has important significance in raising agricultural production efficiency, increasing agricultural income, improving rural ecological environment and other aspects. There is a close relationship between comprehensive utilization value of straw resource and its quantity. As the composition and nutritional value of diverse straws are different and energy is the link of material transformation in the process of straw resource comprehensive utilization, this paper estimates the energy potentiality of crop straw resource and its utilization values from three perspectives based on yearbook data and predecessors'' research results . The main results are as follows, the total energy amount of crop straw resource generally rises from 1992 to 2014, the total amount of crop straw resource are 6.37×1011Kg and 8.26×1018J in weight and energy forms , and suitable feeding crop straw resource is equal to 5.76 ×1011 Kg tons of grain in cereal equivalent form in 2014. At the same time, the computation results of crop straw resource quantity in weight, energy and cereal equivalent forms are consistent, and the computation results in energy and cereal equivalent forms can directly reflect the actual utilization value of straw resources as energy and feed, so it is much more applicable and scientific. At the same time, the energy potentiality values of crop straw in provinces and cities in China has the distinct characteristics of marginal attribute in spatial distribution by quantitative analysis with the method of spatial autocorrelation analysis. As a whole, the potential utilization of straw resources in eastern and northern regions is higher than the western and southern regions.
