【摘要】：户用沼气在我国农村地区已有几十年的使用历史,然而直到目前,我国户用沼气事业的发展仍存在诸多问题,例如户用沼气的布局不够合理,部分地区沼气池得不到持续有效的使用等。因此本研究从这一问题出发,分析了我国农村地区户用沼气适宜性的影响因素,建立了户用沼气适宜性评价指标体系,并对当下及未来一段时间内我国农村地区户用沼气适宜性进行了综合评价与区域规划。首先,从户用沼气的发酵原理,运行方式以及当前户用沼气技术出发,采用理论分析的方法初步确定了户用沼气适宜性的影响因素,接下来基于统计年鉴及相关统计网站的数据,借助SPSS 19.0软件中的相关性分析与回归分析模块对户用沼气区域适宜性影响因素与户用沼气发展水平的相关关系进行了进一步分析,对户用沼气发展较为特殊的地区进行了分析,得出各影响因素与户用沼气发展水平的具体相关关系及相关性强弱,并依据相关性分析结果挑选出最主要的影响因素,这些因素分别为年平均温度,户均畜禽排泄物产气量,以及农民人均纯收入。接下来,依照评价指标体系的设计原则,选定了我国农村地区户用沼气区域适宜性评价指标,建立起户用沼气适宜性评价指标体系,并对各种综合评价方法进行分析比较,选出了最适宜对我国农村地区户用沼气区域适宜性进行综合评价的方法,并对选定的综合评价方法的评价标准进行了规定,对户用沼气适宜性进行了分级,按适宜性强弱化为户用沼气发展的适宜区,次适宜区,不适宜区,以及转变发展模式地区。最后,基于户用沼气适宜性评价的研究成果,利用近几年的年鉴统计数据对现阶段我国农村地区户用沼气适宜性进行了评价与区域规划,给出了我国农村地区户用沼气适宜性区划图;此外,本研究还对未来一段时间内我国农村地区的自然因素,资源因素,社会经济因素的变化趋势进行了预测,并据此分析了适宜性区划结果的变化趋势。
[Abstract]:Household biogas has been used in rural areas for decades. However, up to now, there are still many problems in the development of household biogas in our country. For example, the distribution of household biogas is not reasonable. Biogas digesters in some areas can not be used effectively and so on. Therefore, based on this problem, this study analyzed the influencing factors of household biogas suitability in rural areas of China, and established the evaluation index system of household biogas suitability. The suitability of household biogas in rural areas of China was evaluated and regional planning was carried out at present and in the future. First of all, based on the fermentation principle, operation mode and current household biogas technology of household biogas, the factors affecting the suitability of household biogas are preliminarily determined by the method of theoretical analysis. Then, based on the data of statistical yearbooks and related statistical websites, with the help of correlation analysis and regression analysis module in SPSS 19.0 software, the correlation relationship between the influencing factors of household biogas region suitability and the level of household biogas development is further analyzed. Based on the analysis of the special area of household biogas development, the specific correlation between each influencing factor and the level of household biogas development is obtained, and the most important influencing factors are selected according to the results of the correlation analysis. These factors are annual average temperature, household average output of livestock and poultry excreta, and per capita net income of farmers. Then, according to the design principle of the evaluation index system, selected the domestic biogas suitability evaluation index in the rural areas of our country, established the household biogas suitability evaluation index system, and analyzed and compared various comprehensive evaluation methods. The most suitable method for comprehensive evaluation of the suitability of household biogas in rural areas of China was selected, and the evaluation criteria of the selected comprehensive evaluation methods were stipulated, and the suitability of household biogas was classified. According to the suitability of biogas, the suitable area, the sub-suitable area, the unsuitable area, and the area of changing the development mode are suitable for household biogas development. Finally, based on the research results of household biogas suitability evaluation, this paper evaluates and plans the suitability of household biogas in rural areas of China at present by using the statistical data of yearbooks in recent years. In addition, the trends of natural factors, resource factors and social and economic factors in rural areas in the future are forecasted. Based on this, the change trend of suitability regionalization results was analyzed.
