摘要: 针对目前我国农田水利投资决策中工程项目评价无法全面定量研究成本和效益的问题,本文提出采用能值分析方法对农田水利工程进行生态经济评价的研究思路。以赵口灌区二期工程为例,计算和分析了工程经济、社会和生态环境三方面的成本和效益,根据工程项目的能值成本效益比及评价标准,从生态经济评价角度论证了项目建设的可行性。结果表明,对农田水利工程生态经济评价影响最大是生态环境成本和效益,其次是经济、社会方面的成本和效益,但它们的能值效益成本比分别为6.554.44281.37,可见,工程的社会效益最为显著。从生态经济评价结果来看,该工程具有明显的可行性。

Abstract: Engineering project evaluation is an important means of  farmland and conservancy project during investment decisions. However the present means cannot make a thorough quantitative analysis of all cost and benefit. Aiming at this problem, a new thinking of using energy analysis to make an ecological economic evaluation of  farmland and conservancy project is put forward in this paper. With example of Zhaokou Irrigation Area II Project, the complete analysis and calculation are made from three aspects such as economic, so- cial and ecological environment. The paper demonstrates the feasibility of farmland and conservancy project at the angle of ecological economic evaluation according the EmCBR and its criteria. The results show that the most affected factor in the eco-economic evaluation of farmland water conservancy project is the ecological environment, followed by economic and society. Their EmCBR values are 6.55, 4.44, 281.37, respectively. Therefore, this project has great social benefits. It is shows that the project is practical based on the eco-economic evaluation.
