【摘要】：目前,能源的危机成为国内外热议的话题,也是当今社会最严峻的问题,凸显了人类社会发展与赖以生存的生活环境之间的矛盾,这种矛盾同时促进着社会的进步,人们慢慢开始研究能源危机的对策。能源的危机预示着新能源的出现,而生物质能源现在已经是次于煤炭、石油、天然气之后的第四大能源,开发潜力巨大,终将取代化石能源。秸秆资源是主要的生物质能源,我国农作物产量巨大,巨大的农作物产量带来的巨大数量的农作物秸秆。秸秆由于其生物生理特征,与化石燃料具有共同的元素构成,所以秸秆作为能源化利用是具有可行性的。上世纪80年代全球范围内已有多家厂商投入秸秆的能源化利用经营,现在已经成效明显。我国秸秆能源利用发展相对落后,但是我国是农业大国,科技大国,关于秸秆能源的开发也在飞速发展。本文选取陕西省为研究地区,以《中国统计年鉴2013》、《中国农业统计年鉴2013》、《陕西统计年鉴2013》、《BP世界能源统计报告》中的相关数据为数据基础,参考相关文献,并且加以对陕西省实际情况的调查研究,来确定草谷比、可收集系数、可利用系数、能源转化系数。利用草谷比法计算出陕西省的秸秆资源理论资源量,利用可收集系数法计算出陕西省农作物秸秆的可收集资源量,利用可利用系数法计算出陕西省农作物秸秆的可能源化利用秸秆资源量,最终将可利用的秸秆资源量转化为可替代的化石能源量,并且计算出2003-2012年十年的相关数据,为预测将来的秸秆资源量提供数据基础,计算得到2003-2012年陕西省的理论资源量年均1596.75万吨,相当于624万吨标准煤,若以转化煤炭的方式利用,每年可节约58.13亿元,以转化燃油的方式利用,每年可节约232.55亿元。并分析研究过程中遇到的问题,提出相应的观点与建议。
[Abstract]:At present, the crisis of energy has become a hot topic at home and abroad, and it is also the most serious problem in the society today. It highlights the contradiction between the development of human society and the living environment on which it depends. This contradiction promotes the progress of society at the same time. People are slowly beginning to study the countermeasures of the energy crisis. The energy crisis heralds the emergence of new energy sources, and biomass energy is now the fourth largest energy source after coal, oil and natural gas. Straw resource is the main biomass energy, the crop yield of our country is huge, the huge crop yield brings a huge amount of crop straw. Straw is feasible to be used as energy because of its biophysiological characteristics and common element composition with fossil fuels. In the 1980s, a number of companies have invested in the energy utilization of straw in the world, and now the results are obvious. The utilization of straw energy in China is relatively backward, but our country is a big agricultural country and a big country in science and technology, and the development of straw energy is also developing rapidly. In this paper, Shaanxi Province is selected as the research area, and the relevant data in China Statistical Yearbook 2013, China Agricultural Statistics Yearbook 2013, Shaanxi Statistical Yearbook 2013 and BP World Energy Statistics report are taken as the data basis, and the relevant documents are referred to. In order to determine the ratio of grass to valley, the coefficient of collection, the coefficient of utilization and the coefficient of energy conversion, the actual situation of Shaanxi Province is investigated and studied. The theoretical resources of straw resources in Shaanxi Province were calculated by straw to grain ratio method, and the amount of collected resources of crop straw in Shaanxi Province was calculated by the method of collectable coefficient. Using the method of available coefficient to calculate the amount of crop straw resource which can be used in Shaanxi Province, the amount of straw resource can be converted into the amount of fossil energy which can be replaced, and the relevant data of the decade 2003-2012 are calculated. In order to provide data basis for predicting the amount of straw resources in the future, the theoretical resources of Shaanxi Province from 2003 to 2012 were calculated to be 15.9675 million tons per year, equivalent to 6.24 million tons of standard coal. If used in the form of converted coal, 5.813 billion yuan per year could be saved. Using the converted fuel can save 23.255 billion yuan per year. The problems encountered in the research process are analyzed, and the corresponding viewpoints and suggestions are put forward.
