Abstract The paper has calculated the real and design waste disposal amounts according to the survey of some hydro-power station in the upper reaches of Mingjiang River in July,2006,and got a loss to disposal ratio(LDR),that is,the ratio of loss to disposal in every waste disposal area.The reason and formation of LDR are studied.The reasonable scopes of LDR are proposed in the waste disposal area close to the upper reaches of Mingjiang River for stone tiles and slabs for providing references of soil and water losses prediction to the areas in the near future and similar areas.
