Abstract
On the base of compiling the land reclamation scheme of Wanlong Silica Sand Mine,the economic value of the land reclamation scheme of Wanlong Silica Sand Mine in Zhangwu County was specifically analyzed according to principles of economics with regard to the problems of land reclamation in recent years.Direct and indirect economic benefits were calculated separately according to the differences of land reclamation direction,and the rationality of the land reclamation scheme was assessed by ratio of costs to benefit and static investment recovery period.The results show that the static investment recovery period of the scheme is 2.13 years,which means that the complete cost would be withdrawn and there would be some surpluses at the end of the second year after land reclamation,that the ratio of cost to benefit is about 2.5,far greater than 1,which suggests that the land reclamation scheme is reasonable,and that the environmental benefits,ecological benefits and social benefits of the Wanlong Silica Sand Mine land reclamation scheme are tremendous and it has immeasurable long-term economic benefits.关键词
