| چکیده | ||
| سیستمهای انسانی و طبیعی دینامیک پیچیدهای دارند. تغییراتِ سیستمهای انسانی در سیستم طبیعی بازخوردی بر جای میگذارد. در تغییرات کاربری اراضی نهتنها عوامل محیطی، مانند شرایط جغرافیایی، اثرگذار است، بلکه فاکتورهای انسانی، مانند تغییرات جمعیتی، نیز اثرگذار است، زیرا تغییرات کاربری اراضی تلفیقی از مسائل فیزیکی و اجتماعی- اقتصادی است. مهاجرت بهشدت بر فعالیتهای اقتصادی تأثیر میگذارد و ممکن است آغازگر تغییرات کاربری اراضی باشد. برای تحلیل و بررسی آثار احداث سد طالقان بر تحولات جمعیتی در سیستم انسانی و همچنین تحلیل تغییرات کاربری اراضی در سیستم طبیعی تحقیق حاضر انجام شده است. در این پژوهش، نخست نقشة تغییرات کاربری اراضی تهیه شد. سپس، با محاسبة نرخ تغییرات کاربری اراضی و همچنین نرخ رشد جمعیت به تحلیل نتایج پرداخته شد. به طور کلی، پیش از احداث سد طالقان، منطقة طالقان با کاهش جمعیت همراه بود و، در پی این کاهش جمعیت، میزان اراضی مرتعی نیز در حال کاهش بود، اما، پس از احداث سد طالقان، زمین در این منطقه ارزش یافته و بر جمعیت فصلی افزوده شده است. | ||

| The concept of land use transition highlights that land use change is non-linear and is associated with other societal and biophysical system changes. Changes in human systems has resulted in changes in the natural system such as changes in land use. Land use change causes not only environmental factors like geography and topography are important, but social factors examined such as population growth or decline as well as changes in land use is a mix of economic, social and physical problems. Human societies and their environment, such as feedback, change, uncertainty and adaptation of interaction is social and biophysical changes associated with land use change is non-linear. Changes in human systems with natural systems, such as changes in land use will change. Landuse change causes not only environmental factors like geography and topography should not be involved in social factors such as population growth or decline as well as changes in land use is a mix of economic, social and physical problems. Migration impacts on economic activity seriously and may be initiate land use changes. this study was conducted To analyze the effects of Taleghan dam construction on developments in a human population and land use change analysis in a natural system,In general it can be suggested that in the years before the Taleghan dam, the area's population has been decreasing And pasture lands in the lower level of the population is in decline, but after the dam construction the lands become values in the area and seasonal population increases. | ||
