چکیده

استفاده از فناوری سنجش از دور اغلب موجب کاهش هزینه و افزایش دقت و سرعت شده و روز به روز بر اهمیت این فناوری در راستای توسعه پایدار افزوده می شود. از این رو در تحقیق حاضر امکان استفاده از نسبت های باندی و تجزیه و تحلیل مؤلفه های اصلی با انگیزه دستیابی به مدلی مناسب برای پایش و مطالعه پوشش گیاهی منطقه نیشابور و بررسی رابطه پراکنش پوشش گیاهی با خصوصیات خاک مورد ارزیابی قرار گرفته است. نتایج حاصل نشان داد که نسبت های باندی و آنالیز مؤلفه های اصلی نسبت به اغلب تک باندها در مطالعه و تفکیک پدیده های منطقه مورد مطالعه از قابلیت بالاتری برخوردار هستند. همچنین شاخص های مختلف در شرایط منطقه مذکور نتایج متفاوتی را ارائه می دهند، به طوری که شاخص ها با بالاترین ضریب تبیین در آشکارسازی پوشش گیاهی منطقه نقش مهمی ایفا می کنند. از طرفی روش های به کارگرفته شده بر اساس تفکیک کاربری برای مطالعه تغییرپذیری پوشش منطقه مورد مطالعه نتایج بهتری را ارائه می دهند.

چکیده [English]

Remote sensing techniques are known as very useful methods for studying land use management in arid and semi arid areas, where undeveloped soils are dominant. These techniques can be used for determining different environmental characteristics including soil and vegetations. In this study ETM+ band ratios and Principal component analysis (PCA) were used for monitoring of vegetation cover and its disparity in relation to soil characteristics. Neyshabour area was selected as the study area. The results showed that using of vegetation indices and PCA increased regression coefficients for the model. It was also found that when the analysis is restricted to more homogenous areas, the regression coefficients were improved significantly. It was also concluded that it is possible to develop some statistical models for using of ETM+ images for monitoring vegetation cover in arid areas which are covered dispersedly.
