Abstract

In this study, the economic value of soil conservation function was estimated for the Taham watershed, Zanjan. Therefore, the amount of erosion and sedimentation in the study area was determined using EPM models. Soil nutrient levels were determined with soil sampling and laboratory analysis, and the value of rangeland ecosystems in the maintenance of soil nutrients were estimated separately using the results of soil analysis and opportunity cost method. In addition, the opportunity cost method was used to determine the functions of reduced loss of lands and sediment control. According to the results obtained for total economic value of soil conservation functions, the value of rangeland ecosystems in the study area was estimated to be 1. 44 billion Rials per year, and the economic value per hectare rangeland was determined to be 104000 Rials. Among the vegetation types investigated, the highest economic value was recorded for Feov-Asmi-Brto (171000 Rials per hectare per year). The valuation of soil conservation function can provide accurate information for managers and planners for natural resources conservation, leading to develop more accurate plans in this field.
