摘要
为推动区域农村能源的有效供给和生态环境的良好发展,系统分析了1992—2017年西南高原山区农村生活能源消费变化的时空特征。结果表明,农村生活能源的消费总量和人均消费量呈现先升后降的阶段性变化特征(2008年达到最高),至2017年分别较1992年增加了3.64%和65.13%。煤、秸秆和薪材是农村地区主要的能源消费种类。随时间的推进,沼气、油、液化石油气、天然气、煤气和太阳能消费比例均有不同程度的提高,商品能源比例由1992年的30.05%增加到2017年的57.60%,体现出能源结构由传统的能源利用模式向多元化、优质化和商品化方向转变。能源消费强度的区域分布基本呈现北高南低的特征,能源消费结构也具有明显的区域差异性。因地制宜地采取商品、非商品能源多能互补的农村能源发展模式,重点推进秸秆、薪材等生物质能及太阳能的高效、清洁化利用,是促进西南高原山区农村能源可持续发展的必然选择。
With economic developing and improving,the quantity and quality of rural life energy has been greatly improved.However,some problems,huge waste of resources and environmental pollution,and extensive use of non-renewable fossil fuels,were present.How to guide the rural life energy consumption to change for efficient,clean,environment-friendly direction is the current urgent problem.However,as one of the traditional geographical divisions in China,southwest plateau mountain with abundant biomass resources and distinctive regional characteristics received few studies to research the change of the rural life energy consumption structure in the region.Therefore,to promote sustainable development of regional rural energy in plateau mountain areas of Southwest China,the spatial and temporal variation of rural life energy consumption was analyzed through rural energy data from 1992 to 2017.The total consumption and per capita consumption of rural living energy showed characteristics of gradual change(the highest consumption year is 2008).Coal,straw and fuelwood were main types of energy consumption in rural areas.With the development of time,the consumption proportion of biogas,oil,liquefied petroleum gas,natural gas,gas and solar energy has increased to varying degrees.The proportion of commercial energy has increased from 30.05%in 1992 to 57.60%in 2017,reflecting transformation of energy structure from traditional energy utilization mode to diversification,quality and commercialization.The regional distribution of energy consumption intensity basically showed characteristics of high in the north and low in the south,and the energy consumption structure also has obvious regional differences.According to local conditions,it is an inevitable choice to adopt rural energy development mode of multi-energy complementation of commercial and non-commercial energy,and focus on promoting efficient and clean utilization of biomass energy such as straw and fuelwood and solar energy,so as to promote sustainable development of rural energy in the mountainous areas of the southwest plateau.
