从经济学角度分析公路水土保持措施作为工程产品,涉及到投入资金,就必然考虑到产出效益,这是遵循市场经济的价值规律。公路建设单位由于看不到水土保持措施的巨大的、潜在的生态效益价值的回炉,常常忽略其重要性,这就不可避免地增加了公路水土流失灾害的发生,指出应将生态效益价值纳入项目投资前期的投入产出分析里,并作为项目可实施性的参考指标。
From the perspective of economics analysis of road water and soil conservation measures as engineering products, involves the investment, we must take into account the output efficiency, which is to follow the law of value of the market economy. Because the highway construction unit can not see the huge potential ecological benefit value of the soil and water conservation measures, it often neglects its importance, which inevitably increases the occurrence of highway soil and water loss disasters and points out that the value of ecological benefits should be included in the project Investment in the pre-investment output analysis, and as a project can be implemented as a reference index.
