  Background and objective: Rangelands are important ecosystems with diverse functions in the land that are at risk of destruction. The purpose of this research is to evaluate and determine the areas with potential to carry out rangeland activities under the Plasjan watershed. Material and methods: By reviewing the sources and by Delphi method, the criteria, sub-criteria and limitations of the study were determined. The weights of the criteria were calculated by hierarchical analysis (AHP) method and the layer maps were standardized using fuzzy proportional functions. The rangeland rangeability of the area was determined using multi-criteria assessment (MCE) and with weighted linear combination (WLC) models and weighted sorted averaging (OWA) with medium risk and compensatory capability. Findings: Rangeland capability maps were produced in 6 classes from without range capability to with very high range capability classes. Results have shown in the WLC model, 69249 and in OWA model, 54589 hectares were related to very high capability class. Sparse rangeland in WLC and OWA models, repeatedly with 22981 and 19187 hectares had highest portion in range land capability maps. Discussion and conclusions: Results of this study have shown in WLC model due to high rate of trade-off in comparison of designed OWA model, wider area considers in high and very high range capability class that is related to major area functions that are water reservation and Animal husbandry. This study has shown importance of vegetation characters, land shape and soil character for determining rangeland capability of an area.   Manuscript profile

  Background and Objective: In the present era that a variety of changes in the natural environment has been created, we are obliged to plan and manage land on the basis of the actual and potential of study areaʼs land to achieve sustainable development. The aim of this study is to evaluate the ecological potential for agriculture, range management and determine the consistency of current account agriculture, range management with ecological potential users of this area.Material and Methodology: In this research, first by looking at the different sources and standards, criteria and sub-criteria were selected. The main criteria used in this study include: Soil maps, geology, topography, climate, vegetation, water and land use. Then, layers were evaluated by designing and distributing questionnaires and were weighed by AHP and binary comparison matrix. Finally, all the layers were combined using a weighted linear combination method and the final ecological map can be obtained.Findings: In the final map for the development of agriculture and pasture lands that were taken in 1394, there is not classes 1, 2 and 7of agriculture - range management applications in the final map of these users because the topography, over the rest of the criteria limits the possibility of the agricultural grade 1 and 2 in the study area and from the perspective of range management standards, to the 3rd floor can be seen in the study area. Agricultural Grade 3 is the highest with 31.9% and pasture Grade 3 is the lowest with 11.5% of the land proportion .Discussion and Conclusion: The findings suggest that the combination of AHP and GIS has a high potential for ecological capability evaluation of land for agricultural - range management applications and given that Tajyar dam basin has the potential to develop agricultural activities and pasture In case of exploitation in line with the ecological, local people will be benefited from the effects of the economic expansion of these activities.

  Background and Objective: Forest roads network in forestry plans have main and basic role in the forest management, conservation and recovery. In this research the ability of GIS and AHP in production of road-use map in Dallak kheil forest of Sari with an area of 1521.89 hectare (without villages in study area) was investigated. Method: In this study, for finding a suitable method for optimal routing forest roads and finding environmentally optimal variant of GIS and AHP technique was used. According to effective factors on road planning such as slope, slop direction, soil, geology, stock growth per hectare, hydrology, landscape and conserved species, a questionnaire was provided and then the idea of the experts about forest road planning and relative importance of factors was collected. The factors were weighted in Expert choice (EC) software via pair wise method.Then based on weights, the maps of mentioned factors were overlaid and land capability map with four classes of most unsuitable, unsuitable, suitable and most suitable was produced. Different variants of forest road were designed on land capability map using Arc GIS 9.3 software and divider method. Finally, the status of designed road network and existing road was compared using Backmund and nearest route method. Findings: Analysis of effective factors in the design based on the road design profesionals and forest roads, showed that standard slope with 0.254 relative weight, have the highest points and the outlook with relative weight 0.052 has the lowest points. Discussion and Conclusions:The result of the comparsion betwwen the existing network with five new variants in terms of environmental considerations indicated that the second variant is the best variant due to the passing of the most sutibel areas (19.7%) and unsutibel (21.5%) in compared to the existing road and other variants. Also The second variant whit 62/72 cover persentage in compared to other variants and existing roads in terms of environmental performance were selected as variants better. The Chi square test was used to compare the most suitable variant with existing road. Results showed that the designed road network was significantly better than that of existing road, regarding pass from suitable area. Manuscript profile

  Background and Objective: Arasbaran protected area is located in East Azerbayjan in the northwest of Iran. This area is one of the nine reserves in Iran, and 66.5% of it is covered by forests. In this study, land capability evaluation of this area for forestry was carried out in Geographic Information System (GIS) surrounding. Method: Both Boolean and weighted Linear Combination (WLC) methods along with analytical Hierarchy Process (AHP) were used. First, the ecological characteristics of the study area including elevation, slope, soil texture, climate, value of vegetation type, soil depth and vegetation density were studied and then the calibrated model for forestry in Arasbaran area was created. Findings: In the first step, land capability assessment was done using Boolean method and results showed the presence of class capabilities of third, fourth, fifth, sixth and seventh, and lack of class capability of first and second for forestry. In the next step, the importance of criteria and sub-criteria was calculated using expert’s comments and AHP technique in Expert Choice 11. Then, land capability assessment was done using weighted linear combination. The results showed that all of the seven suitability classes for forestry were proper in the area. Discussion and Conclusion: Mc-Harg systemic model has been used to evaluate the ecologic capability evaluation for many years. The new process in ecologic capability evaluation is to use the mathematical models and to use the analytical hierarchy process for determining the weights and relative importance of the alternatives and for ecologic capability assessment by geographic information systems (GIS). In this study, to evaluate the forestry ecologic capability, both Boolean and WLC methods were used and the advantages and disadvantages of them were investigated. Manuscript profile

  Indiscriminate livestock grazing, rainfed agriculture in sloping lands, cutting of forest trees and other illogical uses of land have caused disturbance of the ecological balance of the environment, erosion of soils and reduction of their fertility in Savadkooh area. The purpose of this study is to determine the best way of exploitation in each of the parts of the land unit, in such a way as to obtain the maximum yield or income, to prevent the destruction of the land and to stop the current process of soil erosion as much as possible. separation of land resources and determination of their capabilities and suitability and talents, land use map of Savadkooh area were determined. Then, by using the FAO method, a detailed evaluation was done using the characteristics of the land and matching them with the tables of plant needs. By combining the results of the aptitude of land and its suitability for various agricultural activities, as well as plant needs and its relationship with the production potential index of suitable areas for agricultural activities in general and horticulture in particular, it is determined. Conclusion: Studies of land potential show that the irremediable limitations and negative factors in horticulture are basically the limitation caused by the impossibility of irrigation in terms of water resource limitations and the limitation of the possibility of mechanization development in terms of the slope of garden lands.
