中国水电科学研究院水灾问题专家刘树坤介绍,防洪投入资金与产生经济效益之比大约是1:10,即投资1亿元,可减少灾害损失10亿元。 防洪投资与一般的投资项目不同的是,防洪投资所产生的效益是无法产生直接经济回报的,只有在遭遇洪灾时这种巨大的社会效益才体现出来。一般投 Liu Shukun, an expert on floods at China Hydropower Research Institute, introduced that the ratio of flood prevention investment to economic benefits is about 1:10, that is, investment of 100 million yuan can reduce the disaster losses by 1 billion yuan. Investment in Flood Control Unlike ordinary investment projects, the benefits derived from investment in flood prevention can not generate direct economic returns. Only in the face of a flood can such huge social benefits be manifested. General vote
