【摘要】：[目的]为明确我国农村能源消费结构的区域特征,推动我国东南丘陵区农村经济和能源环境的可持续发展。[方法]以1991~2014年农村能源的统计数据为基准,选取上海、浙江、福建、江西、湖北、湖南、广东、海南等8个省(市),系统分析了煤、电、油、液化石油气、天然气、煤气、秸秆、柴薪、沼气和太阳能等能源消费结构的变化特征。[结果](1)从能源消费强度看,东南丘陵区农村生活能源消费总量呈现先升高后下降的趋势(以2004年为分界点),2014年较1991年降低了14%;农村生活能源人均消费量呈逐渐升高的趋势,增幅为34%。(2)从能源消费结构来看,非商品能源消费所占比重逐渐下降,而商品能源消费比重显著提升,并于2011年后开始高于非商品能源;秸秆和柴薪的消费比重从1991年的80.8%降至2014年的39.6%,而煤、电、沼气、油、液化石油气、太阳能消费比重均显著增加,分别达到28.4%、17.7%、3.5%、2.9%、4.7%、14%、3%。(3)从能源消费区域结构看,不同省份之间农村生活能源变化存在区域异质性,湖南和海南省生活能源消费总量呈升高趋势,其余5省份则相反;至2014年,浙江、江西、湖南、广东商品能源开始占主导地位,而福建、湖北和海南省秸秆、柴薪的利用比重仍高于50%。[结论]因地制宜开展多元化、重点化、渐进化的农村能源发展模式,推动区域能源结构调整,是保障东南丘陵区农村生活能源有效供应、推动农村经济发展的理性选择。
[Abstract]:[objective] to clarify the regional characteristics of rural energy consumption structure and promote the sustainable development of rural economy and energy environment in southeast hilly region of China. [methods] based on the statistical data of rural energy from 1991 to 2014, 8 provinces (Shanghai, Zhejiang, Fujian, Jiangxi, Hubei, Hunan, Guangdong and Hainan) were selected to systematically analyze coal, electricity, oil, liquefied petroleum gas, natural gas and gas. The change characteristics of energy consumption structure such as straw, firewood, biogas and solar energy. [results] in terms of the intensity of energy consumption, the total consumption of rural energy in the southeast hilly region showed a trend of first increasing and then decreasing (taking 2004 as the dividing point, 2014 decreased by 14% compared with 1991), and the per capita consumption of rural living energy showed a trend of increasing gradually. From the perspective of energy consumption structure, the proportion of non-commodity energy consumption decreased gradually, while the proportion of commodity energy consumption increased significantly, and began to be higher than non-commodity energy after 2011. The proportion of straw and firewood consumption decreased from 80.8% in 1991 to 39.6% in 2014, while the proportion of consumption of coal, electricity, biogas, oil, liquefied petroleum gas and solar energy increased significantly, reaching 28.4% 17.73.50.29% respectively.) in terms of the regional structure of energy consumption, There is regional heterogeneity in the change of rural daily energy among different provinces. The total consumption of energy in Hunan and Hainan Province is on the rise, and the other five provinces are opposite. Until 2014, Zhejiang, Jiangxi, Hunan, Zhejiang, Jiangxi, Hunan, Zhejiang, Jiangxi, Hunan, Commodity energy began to dominate in Guangdong, while straw utilization in Fujian, Hubei and Hainan provinces was still higher than 50%. [conclusion] it is a rational choice to ensure the effective supply of rural life energy and promote the development of rural economy in southeast hilly region by developing the mode of rural energy development with diversification, emphasis and gradual evolution according to local conditions and promoting the adjustment of regional energy structure.
