黄河大柳树水利工程开发的机会成本分析

Analysis on opportunity cost of Daliushu Project in Yellow River

作者应用环境保护效益模型计算和分析了在黄河黑山峡河段修建大柳树水利工程的机会成本,即保护自然景观所获得的休闲娱乐经济效益。分析结果表明,大柳树水利工程的净效益总计为78 9亿元。如果将黑山峡河段保护起来,则需环境保护年效益最少为104 17万元时,才能获得与大柳树水库工程效益相同的效益。但是,目前黄河黑山峡河段没有任何旅游经济收益。所以从目前的现实来看,修建大柳树水利工程的经济效益大于将该河段的环境保护效益。根据统计,与黑山峡河段相距约10km处的沙坡头自然景观旅游区的年旅游收益至少应为400万元,远大于工程年效益。因此,从长远来看,如果黑山峡河段保护起来进行旅游开发应该可以获得更高的经济效益。

The environmental protection benefit model is applied to calculate and analyze the opportunity cost of Daliushu Project in the Yellow River.The calculated result shows if the annual benefit of environmental protection is $10417×104(RMB) at least, it will be same as the total engineering benefit of Daliushu Dam.But now no recreation income from the wild scenery protection can be obtained.In this regard,it may conclude that,at present,it is worth building the Daliushu Project to obtain the engineering benefit including the agricultural irrigation and hydropower benefit.
