【摘要】 黄河下游防洪工程建设项目是为了解决目前黄河下游防洪中存在的主槽淤积严重、堤防质量差、险工高度及强度不足、东平湖滞洪区围坝质量差和下游滩区安全建设标准低等问题而建设的。具体安排了堤防加固、险工加高改建、控导工程建设、滩区安全建设和东平湖滞洪区围坝加固工程。工程净态投资28.41亿元。工程建设期为5年，运行期为30年。 在进行工程的经济效益分析时，通过比较工程建设前后的多年平均洪水灾害损失，来计算工程的经济效益。根据工程的位置、保护范围等将本工程的经济效益分成三部分进行分析计算，即堤防决溢工程效益、东平湖滞洪水库围坝加固工程效益和滩区安全建设效益。 在进行国民经济评价时，依据国家有关规定，选取经济内部收益率、经济净现值和经济效益费用比三个国民经济评价指标。由工程的费用、效益流量过程和经济净效益流量过程计算出该工程的经济内部收益率为15.34％，经济净现值为58201.41万元，经济效益费用比为1.286。并对投资和收益进行了敏感性分析，根据国民经济评价准则进行分析评价，认为该工程盈利能力良好，工程建设在经济上是合理的。更多还原

【Abstract】 The lower reach of Yellow River flood control project, which isAsia Development Bank loaned, aims to solve the increasing riverbed level, the poor embankment quality, the poor quality of Dongping lake embankment, nonstandard construction of the inner floodplain village. The following flood control works will be included: (i) existing embankment strengthening, (ii) river training, (iii) Dongping lake embankment strengthening, construction of the inner floodplain village. The construction period that cost RMB 2.8 billion Yuan is 5 years. The economic life of the project structures is conservatively assumed at 30 years. Estimated benefits were annualized by adjusting the total estimated flood damages to the probabilities of high river flow and the breach embankment, under the "with "and "without" project scenarios. The following benefits are included: (i) benefit of embankment strengthening, (ii) benefit of Dongping lake embankment strengthening, (iii) benefit of inner floodplain construction.The estimated economic internal rate of return (EIRR) is 15.34 percent, economic net present value (ENPV) is RMB 582.0 million, economic benefit cost rate (EBCR) is 1.286. All these proved that this program is appropriate in economic evaluation.更多还原
