| چکیده | ||
| یکی از مهمترین چالشهایی که امروز اکوسیستم جنگلی زاگرس با آن مواجه است پدیده زوال بویژه در درختان بلوط که گونه غالب است، می باشد. پدیده زوال از عوامل متعدد طبیعی و انسانی متاثر است در بین عوامل طبیعی امواج گرما بعنوان پیامد تغییر اقلیم در دو دهه اخیر ظهور پیدا کرده و به زوال جنگل های زاگرس کمک کرده است. به منظور آشکارسازی تاثیر امواج گرما بر زوال جنگلهای زاگرس استان چهار محال و بختیاری پایش مهمترین ویژگیهای امواج گرما شامل فراوانی روز همراه با موج گرم، تعداد رخدادهای موج گرم و تداوم امواج گرم در چهار سایت پایش زوال زاگرس مورد بررسی قرار گرفت. از اطلاعات روزانه نزدیکترین ایستگاههای سینوپتیک به سایتهای زوال برای یک دوره کامل اقلیمی(1991-2019) استفاده شد. ویژگیهای امواج با استفاده از نرمافزار ClimPACT در محیط برنامهنویسی R 2.10 محاسبه شدند. سال شروع موج گرما در سایتهای زوال و روند تغییرات و خطای شیب روند و معنیداری تغییرات امواج گرما استخراج شد؛ نتایج نشان داد با وجود شروع رخداد امواج گرما از 1994 بوده اما به طور پیوسته از سال 2005 همزمان با شروع زوال با شیب تند افزایشی و معنیداری بر فراوانی شدت و مدت امواج گرما افزوده شده است. پیشبینی میشود که تحت افزایش گرم شدن کره زمین این روند بدتر شود. درک روند افزایش اموج گرما در اکوسیستم جنگلی زاگرس میتواند مدیران و تصمیمگیران را در راهکارهای سازگاری با تغییر اقلیم و کاهش اثرات آن رهنمون نماید | ||

| چکیده [English] | ||
| One of the most important challenges facing the Zagros forest ecosystem today is the phenomenon of decay, especially in oak trees, which is the predominant species. The phenomenon of decline is affected by various natural and human factors. Among the natural factors, heat waves have emerged as a result of climate change in the last two decades and have contributed to the decline of Zagros forests. In order to reveal the effect of heat waves on the decline of Zagros forests in Chaharmahal and Bakhtiari province, the most important characteristics of heat waves including frequency of day with hot wave, number of hot wave events and continuity of hot waves in four Zagros decline monitoring sites were studied. Daily data from the nearest synoptic stations to the decay sites were used for a complete climatic period (1991-2019). The wave properties were calculated using ClimPACT software in R 2.10 programming environment. The year of onset of the heat wave at the sites of decay and trend changes and the slope error of the trend and the significance of the heat wave changes were extracted; The results showed that despite the onset of heat waves from 1994, but continuously since 2005 with the onset of decline with a steep upward slope and significantly increased the frequency and duration of heat waves. | ||
