摘要
以黄土高原生态果园模式为研究对象,运用经济技术评价方法分析了在该模式中以沼气为纽带的生态果园经济效益评价的主要指标,并且研究了整个系统中的投入与产出,应用所建立的指标体系对具体案例进行了验证。结果表明:在本案例中,该模式的投资回收期为1.9年,投资利润率为51%,项目净现值为4.2>0,内部收益率为29%>ic(ic=10%)。这些数据说明,该项目具有很好的经济效益。
This paper was based on the loess altiplano eco-orchard model, analyzing the main index of economy benefit evaluation about biogas eco-orchard. Studying mathematic expression and meaning of indexes and investment and output of system. Applying the constructed index verified the practical cases. The result indicated that this model has good economic benefit; Such as investment recoupment period less than two years, investment profit rate is 51%, the presently value of project is 4.20, and the internal benefit ratio is 29%.
