Abstract It is thought that the benefit from watershed management not only includes the value of efficient output in practicality, but also shows as the value of environmental resource much more, the former mainly includes increments of production value from economic crops, forestry, animal husbandry and aquiculture, the latter refers to the values in improvement of ecological environment resource through watershed management, such as water conservation, protection of land resource, carbon fixation and oxygen production as well as transformation of solar energy, wind prevention and desertification control, reduction of natural disasters like flood, decrease of sediment deposition and protection of biodiversity , and the values of social environment resource in the aspects of survival environment improvement and advancement of properties development, etc. Based on the theories of value from labor, boundary effects and that of market value, the index system of value for watershed management benefit and methods to calculate the value of ecological environment were developed using the ways of market value, cost for recovery and shadow engineering. It sets up base for the valuation of benefit from watershed management.
