امروزه استفاده از مدل ها و تكنيك هاي دقيق و جديد مي توانند نقش بسيار مهمي در كمك به حل مسايل شهري داشته باشند. از اين رو تكنيك توليد وزني يك تكنيك بسيار دقيق و ماتريس تصميم گيري آن بر پايه داده هاي عيني است و براي تصميم گيري در زمينه مسائل بسيار حساس كاربرد دارد. هدف از پژوهش حاضر، شناسايي و پهنه بندي نقاط شهري و بخش هاي شهرستان بهمئي در استان كهگيليويه و بويراحمد نسبت به وقوع بحران زلزله مي باشد. براي گردآوري داده ها از سازمان زمين شناسي آمريكا، سازمان نقشه برداري كشور، تصاوير ماهواره اي و غيره، و همچنين براي بررسي و تجزيه و تحليل داده ها از نرم افزار ARC GIS و مدل WASPAS و Dematel استفاده شده است. نتايج حاصل از پژوهش نشان مي دهد، 252 كيلومتر مربع معادل 20 درصد از شهرستان بهمئي در پهنه بدون خطر، 386 كيلومتر مربع در پهنه كم خطر، 289 كيلومتر مربع از شهرستان در پهنه متوسط نسبت به خطر وقوع زلزله و 149 كيلومتر مربع از شهرستان معادل 12 درصد از شهرستان در پهنه با خطر بسيار بالا نسبت به خطر وقوع زلزله قرار دارد. همچنين شهر ليكك مركز شهرستان بهمئي در پهنه هاي با خطر بسيار كم نسبت به خطر وقوع زلزله قرار دارد. همچنين نتايج پژوهش نشان داد كه 160 كيلومتر مربع از بخش مركزي شهرستان، معادل 18 درصد از بخش مركزي در پهنه كم خطر و 212 كيلومتر مربع معادل 18 درصد در پهنه با خطر زياد و 15 درصد از بخش مركزي شهرستان در پهنه با خطر خيلي زياد قرار دارد. همچنين نتايج پژوهش نشان داد كه از مساحت 506 كيلومتر مربع بخش گرمسيري شهرستان، 156/06 كيلومتر مربع معادل 30/84 درصد در پهنه بدون خطر، 44 درصد در پهنه با خطر كم و 6 درصد از بخش گرمسيري شهرستان در پهنه با خطر خيلي زياد قرار دارد. بيشترين مساحت بخش مركزي شهرستان در پهنه با خطر متوسط و بيشترين مساحت بخش گرمسيري شهرستان در پهنه با خطر كم قرار دارد. همچنين تحليل فضايي آسيب پذيري سكونتگاههاي روستايي نشان داد كه، 6 درصد از روستاها و آبادي ها در پهنه خطر خيلي زياد، 8 درصد در پهنه با خطر زياد، 47 درصد در پهنه با خطر كم و 42 روستا در پهنه بدون خطر زلزله قرار دارد.

According placement Country of iran On the belt earthquake Alpine - Himalayas and Placement Partial of Iran Plateau Between two pages of Saudi Arabia (south) an‎d Eurasia (north) an‎d consequently the existence of active faults an‎d the existence of seismic point an‎d most importantly, record high intensity earthquakes, Etc in the township of Bahmei, in The present study will try, with Using the WASPA model, Identified and reviewed The Seismic zones. The main purpose of this study is Identify and zoning Earthquake risk in township Bahmaei and Secondary objectives research: - Review and Assessment City Likak against earthquake risk. - Identify and zoning district township Bahmaei against the danger of earthquakes. - provide strategies to Reduce Damage and and physical and financial vulnerabilities of citizens. According the nature of the subject and research objectives, Research Methodology Based on descriptive – analytical and functional. Collect dates provided in two part, weights and layers of information, based on Documentary method and using satellite images, Mapping organization, USGS organization. The statistical population of the research, the entire limits township Bahmaei based on dividing the national. Indicators used in the study, 10 key indicators, including Active faults, seismic areas, rivers, urban and rural settlements, the elevation, slope and more. To collect data Of the America Geological organization, National mapping organization, Satellite imagery and as well as to review and analyze data used is of ARC GIS software and Wapas model. Results of the research show that from area 1245 square kilometers of Bahmei Township, there are 252.228 square kilometers, equivalent to 20 percent of the Township in an unsafe zone. 149 square kilometers equivalent to 12 percent is in the high risk zone and 167 square kilometers, equivalent to 13 percent in area with the high-risk. Also, of the area of 1245 square kilometers in the Township of Bahmei 386 square kilometers, equivalent to 31 percent is in the zone with low risk of the earthquake. The final weights achieved by each Propeller (weaknesses, strengths, opportunities and threats) in a separate and individual weighting with one another, have dominance of the dominating role of the matrix threat. Results Research shows, 252 square kilometers, equivalent to 40 perecnt of Bahmaei township in zone safe, 386 square kilometers in the zone with low-risk, 289 square kilometers of the township In the zone with middle danger, 149 square kilometers of the township Equivalent with 12 percent of the township In zone with high risk and 167 square kilometers, equivalent to 13 percent is in the zone whit high-risk of ​​the earthquake The city Likak as Bahmaei township center is in zone with low very risk Compared to the risk of earthquakes. Also The results showed The 160 sq. Km of The central part of township Equivalent to 18 percent in zone with low-risk an‎d 137 square kilometers, equivalent to %15 in zone whit high risk and 15 percent of central city The zone have very high hazard. Also the results showed of area 506 square kilometers Section Garmsar, 30 percent in the zone safe, %44 in the zone with low risk and 6 percent is in zone with the very high risk. The also results showed that 15 villages and villages (6%) are very vulnerable, 20 villages (8.43%) are in high danger zones and 112 villages are in zone with low risk.
