| چکیده | ||
| مطالعه خاکها در امتداد یک ردیف پستی و بلندی، اصل مهمی برای بیان مفهوم تکامل و تغییرپذیری مکانی خاکها است که به صورت پیوسته در امتدادی مشخص تشکیل شدهاند. هدف اصلی این پژوهش بررسی دو رویکرد کانیشناسی رس و شاخص شباهت سورنسون در توصیف تشکیل و تکامل خاکهای موجود در اراضی منطقه فسارود (داراب) میباشد. سه واحد فیزیوگرافی؛ واریزههای سنگریزهدار، دشت دامنهای و دشت سیلابی در منطقه تعیین شدند. نه پدون مشاهداتی بر اساس نقشه واحدهای فیزیوگرافی منطقه در امتداد شمال غربی – جنوب شرقی حفر گردیدند. خاکهای واقع در دشت سیلابی بهصورت تیپیک اندواکوئپتز و اکسی اکوئیک هاپل یوستپز ردهبندی شدهاند که فرآیندهای گلیزیشن و اکسیداسیون احیاء در آنها رخ داده است. دو زیرگروه خاک فلوونتیک هاپلیوستپز و تیپیک کلسییوستپز در واحد فیزیوگرافی دشت دامنهای شناسایی شدند که بهترتیب وقوع دورهای فرآیندهای فرسایش و رسوب منجر به کاهش نامنظم کربن آلی و تشکیل افق زیر سطحی کلسیک از مهمترین مشخصههای آنها میباشد. موقعیت واریزههای سنگریزهدار دارای تیپیک یوست اورتنتز است که خاکی جوان و با بیش از 60 درصد سنگریزه در افق زیر سطحی میباشد. کانیشناسی رس نشان داد که کانیهای اسمکتیت، ایلایت، کلرایت، پالیگورسکیت و کائولینیت کانیهای موجود در موقعیت واریزههای سنگریزهدار، دشت دامنهای و دشت سیلابی میباشند. نتایج شاخص تشابه خاکرخی از سطح راسته، زیرراسته، گروه بزرگ، زیرگروه و فامیل بترتیب 5/0، 54/0، 55/0، 74/0 و 74/0 حاصل شد که دارای روندی افزایشی میباشد. به طور کلی رویکرد کمی شاخص تشابه نسبت به کانیشناسی رس بهتر توانسته است تغییرات خاکها را در موقعیتهای مختلف شیب توصیف نماید. | ||

| Surveying of soils along a toposequence is a primary key for identification of the spatial variability and development of soils that have been performed continuously at a certain direction. The main objective of this study is to assess both clay mineralogy and Sorensen similarity index to describe the genesis and development of soils in Fasarood region. In this context, three major physiographical units were recognized in this area (i.e., Colluvial fan, Piedmont plain and Flood plain). Moreover, nine presentative pedons were digged according to physiographical map units in the direction of NW to SE. Typic Endoaquepts and Oxyaquic Haplustepts are identified as dominant soils in the flood plain in which the redoximorphic and gleyzation processes have been occurred. Fluventic Haplustepts and Typic Calciustepts were recognized in the piedmont plain along with an irregular decrease in organic-carbon content as well as calcic horizon, caused by erosion and sedimentation, respectively. Typic Ustorthents is the major soil of Colluvial fan that have more than 60% coarse fragment in subsurface horizon. The results revealed that smectite, illite, cholorite, palygorskite and kaolinite were dominating minerals in colluvial fan, piedmont plain and flood plain. According to the similarity index, 0.5, 0.54, 0.55, 0.74 and 0.74 were achieved for order, suborder, great group, sub group, and family levels, respectively. Generally, similarity index could better describe soil variation in different slope position than clay mineralogy due to its quantity approach. | ||
