Abstract

One of the existing problems in studying natural resources is lack of standard and determined method so that, different methods for studies are applied with attention to existing conditions and skilled - men views. For example, watershed management, range management, and desertification have separate definitions which caused many problems in plans. In this research, two methods namely geomorphology and environmental were used for studying natural resources plans. In this study, Bidvaz watershed was chosen in Khorasan province in Esferayen city. Mentioned methods were compared in this cachments. 190 programming units were obtained (apart from units less than 25ha.) by ENVIRONMENTAL METHOD. Since compiling 190 programming units in 50000 ha. Is too difficult, so this method can not be used in watershed, rangelands and desertification, but it can be used in, identification of environment units in vast area (for example a province). On the other hand, quantitative and qualitative erosion can not be estimated by ENVIRONMENTAL METHOD. In mentioned catchment, 32 programming units were chosen according to GEOMORPHOLOGY METHOD. Thus, costs of studies in 32 units are less than 190 units. Finally programming units can be mixed with some common units then to reduce programming units more. By this method, soil erosion can be studied easily and with high percision from the viewpoint of quality and quantity and vegetation can be studied and planned in each programming unit according to other physical factors like water and soil.
