| 摘 要： | 以宜昌县为例，在系统分析该县农村能源、农村经济和环境之间的关系及农村能源建设现状的基础上，建立了该县能源生态工程建设系统的结构模型及系统动力学模型，经过DYNAMO语言反复的仿真试验，研究该能源生态工程建设系统在当今市场经济的条件下未来30年的发展趋势，观察系统状态的动态变化。模拟结果表明：通过大力发展小水电、沼气和努力提高热效率，30年后，该县薪柴和秸秆的供能比例从54.73%下降到34.03%，土壤有机质从1.2 g/kg增加到2.0646 g/kg，森林覆盖率从32.3%提高到60.6%，实现了能源、生态效益同步增长。

| Abstract: | The paper is based on the system analysis of the relationship among rural energy, rural economy, environment and the situation of the energy ecology system in the county. The author took Yichang country as an example to design a structure model of the county of Yichang Energy Ecology Engineering Development System (EEEDS). Then using the System Dynamics (SD), a SD model of Energy Ecology Engineering Development System was established and the trend of the EEEDS in the situation of the market-oriented economy after 30 years was studied. Dynamic state of the system was observed. Dynamic results were obtained: small hydropower station and biogas and promoting efficiency of heat were greatly developed. Percentage which fuel forest and straw are supplied for energy is reduced from 54.73% to 34.06%, organic matter of soil is increased from 1.20 g/kg to 2.06 g/kg, the percentage of forest cover is raised from 32.3% to 60.6% in Yichang County after 30 years. The benefit of energy and ecology is simultaneously increased. |
