Abstract

The aim of this study was to provide a multi-factor ecological power model based on the ecological factors of hydrological response units in order to assess the ecological potential of different uses in the Zailakirood Basin, northern Iran. First, by employing ArcSWAT, 608 units of hydrologic responses in 39197 independent polygons were found in the study area. Then, by measuring the hydrological response units using special ecological capability models, the yield of the studied lands was measured in terms of production, quality of vulnerability and management requirements. In the next step, the final vulnerability of the hydrological response units to the degradation caused by the forest utilization was quantified by hydrological indicators. In order to evaluate the hydrologic indices, using the SWAT model, calibration and sensitivity analysis, the effective parameters for runoff and sediment simulation were obtained. In each hydrological response unit, the numerical value of the hydrologic indices was estimated, then the hydrological response units with the capability of producing sediments more than the determined limit of the index was changed to protective and supportive usage. So that, the usage of potential of utilization 1 of forestry and centralized ecotourism capacity 1 remained without changing in the area, potential of utilization 2, 3 and 4 of forestry and centralized ecotourism capacity 2 decreased in the area. Finally protection and supportive function with an area of 14083 ha increased. Since slope, soil and land use have the highest variations in the region and cause the most limitations, application of hydrological response units for classifying the ecological capacity usage and simulating the parameters of management allow Quantitative vulnerability assessment is considered as a perfect tool for assessing the capacity of the land.
