[ 1 ] - GIS-Based Monitoring and Ewss of Desertification (Case Study; Southeastern of Iran)

Today one of the ecological crisis is the phenomenon of desertification that affecting the world. Desertification is more related to social and anthropogenic issues than natural causes and it becomes more important over the time. Monitoringis the systematic collection and analysis of information as a project progresses. In this study, using AHP method and GIS techniques has been to assess deser...

[ 2 ] - پایش تغییرات کاربری اراضی و تأثیر آن بر روند تخریب زمین و بیابان‌زایی با استفاده از تصاویر ماهواره‌ای لندست (مطالعه‌ی موردی: شرق ایران، دریاچه‌ی هامون)

Nowadays, remote sensing and GIS technologies are used as a key element in monitoring of land use and vegetation changes. Using this method as one the main sources receiving and updating information on the Earth's surface changes, plays an important role in the management of ecosystems. The present study aims to investigate land use change, vegetation dynamics and trend of Hamoun wetland betwee...

[ 4 ] - مدل‌سازی ارزیابی تخریب زمین و ارائه سیستم‌ هشدار اولیۀ بیابان‌زایی

Land degradation are known in dry lands as a physical - environmental and economic - social phenomenon that eventually lead to declining of soil fertility. Several processes are caused this as well as one of them is desertification. In this research attempt to modeling the process of desertification with use IMDPA model in a ten years period in southeast coastal of Iran desert, the first. Final...

[ 6 ] - واکاوی و پهنه‌بندی انرژی باد بر اساس قابلیت حمل ماسه در راه‌آهن قم-تهران

     با توجه به حاکمیت مناطق بیابانی در وسعت زیادی از ایران، بررسی و مطالعه رژیم بادی به‌منظور طراحی ایمن خطوط ریلی و همچنین حمل رسوبات بادی از اهمیت قابل‌توجهی برخوردار است. در این پژوهش به واکاوی رژیم بادی و قابلیت حمل ماسه با استفاده از روش فرایبرگر در ایستگاه‌های هواشناسی موجود در حاشیه راه‌آهن قم-تهران به طول 178 کیلومتر پرداخته ‌شده است. گلبادهای سالیانه نشان می‌دهند که درمجموع حاکمیت باد...
