چکیده

مطالعات خاکشناسی و تناسب اراضی برای اجرای یک پژوهش کاربردی و اطلاع از ویژگی­های خاک و اراضی ضروری است. هدف این تحقیق، تعیین مکان­های مناسب در شرایط فعلی و آتی برای برخی محصول­های زراعی و باغی بود. منطقه مورد مطالعه با وسعت 295 هکتار در منطقه آبیک قزوین واقع­است. رژیم رطوبتی و حرارتی منطقه به­ترتیب اریدیک ضعیف و ترمیک بود. فیزیوگرافی­های غالب، مخروط­افکنه آبرفتی و دشت‌ دامنه‌ای هستند که برای کشاورزی تسطیح شده­بودند. 9 خاک­رخ در منطقه تشریح­شد و بر اساس رده­بندی آمریکایی، خاک‌ها در دو رده انتی‌سول و اریدی‌سول طبقه­بندی شدند. تناسب اراضی فعلی و آتی 5 نوع بهره‌وری (شامل کلزای پاییزه، گوجه­فرنگی، سیب، گلابی و گردو) با توجه به شرایط اقلیم، خاک و زمین بررسی شد. نتایج نشان داد، وجود مقدار نسبتاً زیاد تا زیاد سنگ، سنگریزه، قلوه­سنگ، کربنات کلسیم معادل و pH خاک، مهم‌ترین عوامل محدوده­کننده برای انواع بهره‌وری می‌باشند. برای گوجه­فرنگی و گردو، کلاس تناسب اراضی نمی­تواند به S1 ارتقاء یابد. زیرا شرایط اقلیمی منطقه برای آن­ها کم­و­بیش محدودیت­‌زا است. اما کلاس تناسب اراضی برای سایر انواع بهره­وری­ها با انجام اقدامات مدیریتی مناسب می‌تواند ارتقاء پیدا کند. کلاس تناسب اراضی سایر نوع‌های بهره‌وری اراضی با اجرای اقدامات مدیریت اراضی قابل بهبود می­باشد. به­ترتیب 40% و 43% از کل اراضی منطقه برای کاربری باغ و زراعت آبی مناسب (کلاس S1) است. درنهایت 17% باقی­مانده نیز به­علت وجود محدودیت­های زیاد می‌تواند برای کاربری­های غیر کشاورزی مورداستفاده قرار­گیرد.

چکیده [English]

Soil surveying and land suitability are essential for conducting an applied research and acquiring land and soil characteristics information. The aim of this study was to detect appropriate zones for some chosen agricultural and horticultural plants in current and future conditions. The studied region with an area of 295 hectares was located at Abyek region in Qazvin province. Soil moisture and temperature regimes were Weak Aridic and Thermic, respectively. Alluvial fan and piedmont plain were predominant physiographics that were leveled for agricultural purposes. Nine soil profiles were described and classified based on soil taxonomy,which were placed in Aridisols and Entisols order. Current and future land suitabilities were surveyed taking into account of the climate, soil and land conditions for five land utilitization type (including: autumn canola, tomato, apple, pear and walnut). The results showed that existence of relatively large amount of stone, gravel, rubble, carbonate calcium equivalent and soil pH were the most important limitation factors for different utilization types. For tomato and walnut, land suitability class couldn’t be promoted to S1 (no limitation). It was because of climate condition of the region that was more or less restrictive for them. However, land suitability class for other LUTs could be improved by implementing suitable land management practices. Also, 40% and 43% of the total study area were suitable (S1) for horticultural and irrigated agricultural use, respectively. Finally, due to high limitations, the remaining 17% of area could be used for non-agricultural purposes.
