Abstract

Extended Abstract:Introduction: BINALOOD Mountain Range is a trusted system located in the north east of Iran. It is part of the dry and semi-arid mountains of the country. The slopes of this mountain range due to different lithological conditions and rock resistance against weathering and erosion, climatic characteristics and severe changes anthropogenic, including land use, has a good position for occurrence of geomorphological hazards there are some kinds of DOMAIN INSTABILITY, especially these instabilities there are frequent events that poke a threat to life, equipment, facilities and transportation routes within the desired range. According to statistics, slippery slopes and various types of instability in the mountainous areas of the BINALOOD Zone since the 1370 have been exacerbated. Therefore, it makes doubling the importance of addressing the subject. According to field studies in the northern and southern slopes of Binaloud, the exacerbation of the risk of mass movements of the range, and in particular of the risk of slipping, has a widespread frequency and range than other environmental and geomorphic hazards. Factors such as grazing over the livestock capacity and tract created by kicking the soil caused by the movement of the livestock, falling slopes, with unconventional horticulture on the terraces of alluvium and on steep slopes, Severe land use changes, especially in sloping slopes, are one of the most important factors in day-to-day and the intensification of sloping movements and the occurrence of destructive currents in the northern and southern slopes of BINALOOD. BINALOOD mountain range The geographic location of the mountain range is semi-arid with a length of 143.75 km With the northwest trend - south-east extending from south east and from Quchan to northeast of Neyshabur.Methodology: The research method used in this research is an analytical and inductive system And to the feasibility of occurrence of sloping instabilities as one of the most important geomorphic hazards in the northern and southern slopes of BINALOOD Which has a devastating impact on the settlements of the human communities. in the region In order to identify the factors influencing this phenomenon, 11 variables such as variables Slope, slope of geological layers, lithology units, distance from fault, land use and coverage, consistent lines and homogeneity, altitudes and other factors. Based on the topographic map of 1/25000 at different levels of natural and human studies, In this regard, firstly, the hydrological basins in the study area were found to be in the realm of research in total of 33 catchment areas including 23 basins in the northern slope and 10 catchments in the southern slopes were identified.Results and discussion: Investigating the variables in the Binaloud region in the form of reference land, and lateral spatial modeling were arranged in GIS software and processed in Autocad software Therefore, the produced production maps are evaluated by the ANP method and subjected to the following expeater selection software in the form of main criteria and sub criteria. In the ANP method, we accurately analyzed the parameters in pairs and compared to the 11 variables of the present study, the results showed that the parameters of slope, altitudes, lithology units, faults, land use and land cover, and .... Respectively, have the highest gained weight. Finally, these maps were overlapping and zoning in GIS software with fuzzy logic and fuzzy aggregate operator. The hazard zonation map generated from this model, as a reference map, is adapted to the initial map prepared through field observations, spatial coordinates with GPS, and aerial photo interpretation. Its results were analyzed and analyzed from the perspective of environmental management.Conclusion: Finally, based on the statistical results extracted from these maps, testing the assumptions about the probability of occurrence of slopes and especially landslides And its effect on environmental management, using Spearman and Kendall tests in SPSS software, the results of which prove the hypotheses With a probability higher than 95%. According to the results of this study, the gradient is the most effective factor in the incidence of domain inconsistencies in each other and due to the geologic form of the formation, the most frequent occurrence of landslides occurs in the northern and southern silty and subtropical slopes of the southern slopes of the southern slopes. And the best environmental MANAGEMENT APPROACH to reduce the risk of insecurity in the Binaloud Mountain Range, to identify vulnerable zones of danger, land allocation, and land use capability and to prevent land use change based on sub-optimal results.
