In order to explore the methods and ways of supervising the construction of soil and water conservation-based eco-environment project,to quicken supervising the construction of soil and water conservation-based ecoenvironment works development towards regularization,standardization and scientism,the system of supervising the construction at Xihe demonstration area of soil and water conservation in the Yellow river valley was carried out. Practices indicated that,it is positive and feasible,and could yield notable results. It improves the engineering quantity,controls the engineering investment and promotes the engineering progress effectively. T he facing problems and countermeasures are proposed about present supervising the construction of soil and water conservation- based eco-environment according to living example analysis and summing-up experience,so as to advance,to perfect and to popularize the system of supervising construction of soil and water conservation-based eco-environment project.
