زلزله یکی از خطرناک ترین بلایای طبیعی عصر حاضر می باشد که همواره اهمیت خود را به طور عینی نمایان کرده است. زلزله سانحه ای طبیعی است که بر اساس میزان بزرگی خود می تواند در مدت کوتاهی فجایع عظیمی بی آفریند.با توجه به اینکه اصلی ترین نیاز آسیب دیدگان ناشی از زلزله داشتن یک سرپناه می باشد (سرپناهی که تمام نیازهای افراد را مدنظر قرار داده و مطابق آن ساخته شده باشد) و نمی توان بعد از وقوع زلزله، سریع امکان های مناسب برای آسیب دیدگان زلزله را تهیه دید، باید قبل از وقوع چنین بحران هایی، مکان های مناسب را برای آسیب دیدگان زلزله را فراهم کرد. تحلیل تناسب اراضی، فرآیند تعیین قابلیت یک قطعه زمین مشخص برای تخصیص یک کاربری معین است، بدیهی است عدم رعایت تحلیل تناسب اراضی ممکن است فاجعه دیگری حتی به مراتب وخیم تر از سانحه اولیه به دنبال داشته باشد.هدف پژوهش حاضر تحلیل تناسب اراضی جهت اسکان موقت پس از زلزله احتمالی در شهر لواسان می باشد. لواسان به دلیل قرارگیری بر روی دو گسل شمال تهران و گسل مشاء، شهری لرزه خیز است و می بایست برای شرایط پس از زلزله در این شهر ، تمهیداتی اندیشید. در این پژوهش ابتدا معیارهای موثر در مکان یابی مراکز اسکان موقت را شناسایی کرده سپس با استفاده از روش AHP به وزندهی این معیارها و زیرمعیارهای مربوط به آن پرداخته ایم در مرحله بعد با اعمال این وزن ها در نرم افزار GIS نقشه های مربوط به هرکدام تهیه نموده ایم. در انتها با توجه به تجزیه و تحلیل داده ها و تحلیل تناسب اراضی در شهر لواسان، اراضی مناسب جهت اسکان موقت، شناسایی و خروجی حاصل شده و با واقعیت زمین، کنترل و انطباق داده شده است. بر اساس بررسی نتایج تحقیق و نقشه ی استخراج شده و همچنین مطالعه میدانی، اراضی مناسب برای برپایی اسکان موقت در زمان وقوع زلزله در شهر لواسان در ناحیه شرقی این شهر می باشند که شامل پارک ها و ورزشگاه می باشد.

Earthquake is one of the most dangerous and harmful natural disasters of the present era, which has always shown its importance objectively. Earthquake is a natural disaster that, based on its magnitude, can cause huge disasters in a short period of time. Due to its location on two faults north of Tehran and the Masha fault, Lavasan is an earthquake-prone city, and preparations should be made for post-earthquake conditions in this city. Earthquake is a natural disaster that, based on its magnitude, can cause huge disasters in a short period of time.Considering that the main need of the earthquake victims is to have a shelter and it is not possible to provide suitable facilities for the earthquake victims quickly after the earthquake, it is necessary to From the occurrence of such crises, he provided suitable places for the victims of the earthquake. Appropriate temporary housing facilities protect earthquake victims from difficult environmental conditions, strengthen their sense of security and stability, and enable them to resume daily life and activities. Land suitability analysis is the process of determining the suitability of a certain piece of land for the allocation of a certain use. It is obvious that failure to comply with the land suitability analysis may lead to another disaster even far more serious than the initial disaster. The housing crisis is one of the inevitable consequences of the earthquake due to widespread destruction; Therefore, housing management is an important part in post-disaster conditions. According to the mentioned cases, land suitability analysis for temporary settlement after a possible earthquake in the cityLavasan using multi-criteria decision-making technique and GIS software, the current research is done.Determining the right place for the establishment of various urban uses depends on several factors, these factors are determined according to the nature and type of related user activity. Therefore, by considering the main features and characteristics that a suitable place for temporary housing should have, the influencing factors can be determined. After choosing the effective criteria and sub-criteria in land suitability analysis, in order to combine them with each other in the form of information layers, the weight of each of them should be determined according to their importance. Because some criteria are more important than other criteria and play a decisive role in land suitability analysis. The weight of each criterion indicates its importance and value compared to other criteria. The criteria studied in this research include:Natural factors include: fault, cause;Physical factors include: access to communication passages, bridges;Functional factors include: proximity to water sources, proximity to medical centers, proximity to firefighting centers.In this research, which is of a quantitative type, in addition to library surveys and the use of available sources, various maps have also been used. Criterion maps were classified according to the objectives and multi-criteria decision making method. After identifying the effective criteria in locating the temporary housing and preparing a hierarchy chart, the decision makers were asked to compare the criteria and express the relative importance of the elements using numbers, by evaluating the criteria and sub-criteria according to the weights. Obtained from pairwise comparison using the multi-criteria decision making technique, which is in the softwareExpertChoice has been loaded, The weight of each criterion using the toolRaster Calculator In the raster layer, each criterion is multiplied and their sum creates the final map. Finally, the extracted areas were divided into 9 categories (Unsuitable range in red, to completely suitable range in green), the green parts are suitable lands for temporary housing after the earthquake in this region.The eastern region of the studied area has better and more favorable conditions for the construction of temporary accommodation after the earthquake, which includes parks and stadiums.The use of GIS software along with the use of multi-criteria decision-making techniques can work well in the discussion of land suitability analysis and bring us to the final Target of the research; However, the more the number of research criteria and the smaller the research limitation, the more accurate results will be obtained.

هر مکان روستایی با توجه به میزان جمعیت ساکن در آن، جهت پاسخگویی به نیازهای آنان باید عملکردها و کاربری های گوناگون را در خود داشته باشد. برای آن که فعالیت های مختلف در مکان های مناسب استقرار یابد و روابط مطلوبی با همدیگر داشته باشند، تدوین طرح ارزیابی کاربری زمین بدنبال تهیه برنامه کاربری اراضی ضروری به نظر می رسد. هدف این تحقیق، بررسی عوامل موثر بر تحقق پذیری کاربری های پیشنهادی در طرح های هادی روستایی از دیدگاه سه گروه (کارشناسان بنیاد، اساتید و مشاورین طرح های هادی) می باشد. روش به کار رفته در این تحقیق، فرایند تحلیل سلسله مراتبی یا AHP است. به این ترتیب از ارتباط بین اهداف، معیارها، زیر معیارها و معرف ها یک ساختار سلسله مراتبی تهیه شده است. سپس ضریب اهمیت معیارها و زیر معیارها، وزن معرف ها، و امتیاز نهایی شاخص ها و معرف ها محاسبه و سازگاری منطقی قضاوت های کارشناسان مربوطه بررسی شد. مراحل یاد شده، با استفاده از نرم افزار Expert Choice، صورت گرفته است. دلایل تحقق پذیری در 5 گروه دلایل اقتصادی، اجتماعی، فضایی-کالبدی، اکولوژیک و سازمانی- مدیریتی مورد بررسی قرار گرفته است. بر اساس نظرات سه گروه اساتید دانشگاه، کارشناسان و مهندسین مشاور بنیاد مسکن، شاخص مدیریتی (با وزن 405/0)، اقتصادی (با وزن 3/0)، اجتماعی (با وزن 157/0)، فضایی- کالبدی (با وزن 098/0) و در نهایت شاخص اکولوژیک (با وزن 04/0) به ترتیب اولویت 1 تا 5 را در تحقق پذیری کاربری های پیشنهادی دریافت کرده اند.

To establish different activities in appropriate places and favorably organize their relations with one another, it is necessary to develop a plan to evaluate the success rate of the proposed organization, thus the Land-use Plan was launched. The purpose of this study was to investigate the factors effective in the realization of proposed functions in Rural Guide Plans from the perspective of three groups (the experts of The Housing Foundation of the Islamic Republic of Iran, academic scholars, and consultant engineers responsible for Rural Guide Plans). With regard to the scope of the study, this is an applied research, but in nature it is a descriptive-analytical one. Analytical Hierarchy Process or AHP was used to make carful decisions in choosing the variables effective in realization of the applications in Rural Guide Plans, while taking the relevant priority of factors into consideration. Therefore, based on the relationship between the purposes, criteria, sub-criteria and indicators, a hierarchical structure was provided. Then, the index of importance of criterions, subcriteria, the weight of indicators, and the final scores of indexes and indicators were calculated and the logical compatibility of the expert's judgment was examined. The above-mentioned process was carried out by Expert Choice Software package. The reasons for realization were examined in five groups: economic, social, spatial-physical, ecological and organizational-managerial. According to the ideas of three groups, i.e., university professors, experts and consulting engineersfor the Housing Foundation of the Islamic Republic of Iran, the management index (weighing 0.405),economical index (weighing 0.3), social index (weighing 0.157), spatial-physical index (weighing 0.098) and ecological index (weighing 0.04) respectively received the 1st to 5th priority in realization of the proposed function. Field studies on rural areas of Iran confirm that managerial issues play an important role in realization or lack of realization of suggested land use for rural plans. It also shows that in rural communities, in addition to the role of village manager in communication between organizations for allocation of these function, there are other challenges like the lack offunds, the lack opportunities for public participation, and physical restrictions in some villages for locating specific land use, etc. Among the secondary indexes effective in the realization of suggested functions, the sub-indexes of proper allocation of proposed budget (weighing 0.19), integrated management (weighing 0.14) and proper management of budget (weighing 0.08) had the highest weight. On the other hands, factors such as proper underlying map (weighing 0.01), attention to climatic condition (weighing 0.01) and communication situation (weighing 0.01) had the lowest weight. Although this research, on a quantitative level, was conducted among three groups of the statistical population, it has tried to examine the factors effective in realization of proposed land use, the study results agree with the established facts of rural areas in Iran.Keywords: rural settlements, land use analysis, Rural Guide Plan, Analytical Hierarchy Process (AHP), Expert Choice Software
