چکیده

شهرستان تنکابن دارای 13 ایستگاه باران سنجی و یک ایستگاه کلیماتولوژی غیر فعال می‌باشد. نظر به بعد مسافتی این شهرستان با ایستگاه‌های ‌سینوپتیک موجودمی‌توان با توجه به مساحت شهرستان تنکابن به مکان‌یابی یک ایستگاه جدید سینوپتیک در شهرستان تنکابن اقدام نمود تا ضمن حل مشکل فاصله بین ایستگاه‌های ‌موجوددر مطالعات اقلیمی و برنامه ریزی‌های ‌شهری و عمرانی نیز از داده‌های ‌ایستگاه جدید استفاده کرد. تحقیق حاضر از نوع کاربردی و رویکرد حاکم بر آن تحلیلی و ترکیبی است. برای تجزیه و تحلیل اطلاعات از نرم‌افزارهای گرافیک‌مبنا مانند ARC GIS10 و آمار‌مبنا شامل PASW و Choise Expert استفاده گردیده است. هم چنین جهت تلفیق و استخراج وزن‌های ‌موثر در عملیات مکان‌یابی از مدل فرآیند تحلیل سلسله مراتبی (AHP) و روش هم‌پوشانی وزنی و منطق فازی استفاده شده است. نتایج تحقیق حاضر نشان می‌دهد با توجه به تلفیق فاکتورهای هفتگانه با مدل هم‌پوشانی وزنی و استفاده از مدل AHP81/6 کیلومترمربع از منطقه مورد مطالعه دارای پتانسیل بسیار مناسب جهت احداث ایستگاه سینوپتیک می‌باشداین منطقه در شمال شهرستان متمرکز شده است و در حدود 38/0 درصد مساحت شهرستاناین قابلیت را دارا می‌باشد. هم چنین نتایج تلفیق نقشه‌های ‌فاکتور با مدل فازی،1/2 کیلومترمربع از مساحت شهرستان را دارای قابلیت بسیار مناسب جهت احداث ایستگاه سینوپتیک معرفی می‌نماید. با توجه به مقایسه دو نقشه نهایی مدل فازی به دلیل قابلیت انعطاف بالاتر نسبت به مدل هم‌پوشانی وزنی به عنوان مدل بهینه جهت اولویت بندی شهرستان به منظور احداث ایستگاه سینوپتیک معرفی می‌گردد.

چکیده [English]

Tonekabon has 13 pluviometry stations as well as one climatological station which is inactive. Due to the distance of the city with existing synoptic stations and with regard to the area of the city, it is attempted to position a new synoptic station so as to both resolve the problem with the distance between the stations available and also to use the new station data for climate studies as well as urban planning and construction. This research was practical with an analysis-combination approach. In order to analyze the data , graphic-based software’s  ARC GIS10  and  statistical -besd PASW & Choise Expert, is used. Additionally, in order to integrate and extract effective weights in the positioning operation, the models of analytic hierarchy process (AHP), weighted overlap, and fuzzy logic were used. The results of the study showed that due to the combination of seven factors with weighted overlap model as well as using the AHP model, 81/6 square kilometers of the area under study had great potential to be suitable for the construction of synoptic stations, which was mainly concentrated in the north part of the city. Moreover, about%38 of the city area had such capability. The results obtained from the combination of factor maps with the fuzzy model introduced that half square kilometers of the city area had the right capabilities to construct synoptic stations. Regarding the comparison of the two final maps, the fuzzy model due to its higher flexibility than the weighted overlap model was introduced as the optimum model for prioritizing the city to build synoptic stations.
