陇中黄土丘陵地区经济贫困、环境脆弱、生活能源短缺,生物质过量消费成为生态环境退化的重要驱动因素。论文通过问卷调查获取相关数据,并建立计量模型,基于替代性分析估算了不同用能结构情景下的环境经济成本。结果表明,现状户均生活能源消费2112.44kgce/a,人均428.59kgce/a,用能水平较低。目前农户消费能源选择的主要依据是能源的现金支出和可获得性。与农户现状用能结构相比较,4种替代结构的能源消费总成本、环境成本、经济成本及现金支出差异较大。利用沼气和太阳能的结构各项成本低,应是今后农村能源建设的方向。 |

Due to poverty in economy, serious soil erosion and shortage of rural household energy in loess hilly region of Gansu Province, excessive consumption of biofuel becomes an important driving factor of eco-environmental of degeneration. Data on rural household energy use was obtained by questionnaires in this research, and based on substitutable analysis, environmental and economic costs under different energy consumption structures were estimated by the quantitative model. Results show that one family consumes 2112.44 kgce and per capita 428.59kgce per year at present, an indication of a lower level of energy consumption. The total energy consumption cost of per household is 1925.65yuan/a, in which the environmental cost is 621.13 yuan/a and the economic cost is 1304.52 yuan,/a. Commercial energy has been used widely. The per household cash payment is 536.51yuan/a that is 8.69% of the household net income. The full use of solar energy and biogas can obviously decrease the above-mentioned cost of energy consumption. Cash payout and gettable capacity of energy are the main reasons for the rural households to choose energy categories. To compare with the actual structure of energy usage, there are obvious differences on the total cost, the environment cost, economic cost and cash payout for households among the four substitutable structures. Each item of cost is lower when biogas and solar energy are used, so this structure is the primary direction for the future development of rural energy. |
