В Армении деградация почв обусловлена разными факторами, в том числе и чрезмерным стравливанием пастбищ, и является серьезной проблемой с точки зрения продовольственной безопасности и устойчивого развития. Оценка деградации почв важна для определения возможных последствий и потенциальных мер управления. В данной работе рассматривается возможность определения отдельных компонентов земной поверхности, связанных с деградацией (ППР, ППОП и ППК), методами ЛСР и НРВИ-АСС, используя космический снимок QuickBird, и их применимость для оценки и картографирования деградированности пастбищных земель. Как показывают результаты, методы ЛСР и НРВИ-АСС применительно к космическому снимку QuickBird дают уникальную возможность для точного определения ППР, ППОП, а предложенный метод оценки и картографирования деградации почв адекватно отражает реальную ситуацию.
