Abstract

The purpose of this study was to determine the relationships between soil moisture and backscattering coefficient values calculated for each sampling plot and compare with soil moisture in different forest sites and crown closure classes using Radarsat satellite images in Artvin-Merkez and Gümüşhane-Karanlıkdere forest planning units. Results indicate that in low coverage and degraded forest areas in dry and fresh-moderate fresh forest sites in Artvin forest planning unit, the relations between soil moisture and backscatter coefficient values were negatively correlated with r=-0.85 and r=-0.73, respectively. However, there was no relationship between backscatter coefficient values and soil moisture in medium crown coverage and full coverage stands. Similarly, at low coverage and degraded forest areas in very dry-dry and fresh-moderate fresh forest sites in Gümüşhane-Karanlıkdere forest planning unit were positively correlated high and significant r=0.78 and r=0.83, respectively

Özet

Bu çalışmanın amacı, Artvin-Merkez ve Gümüşhane-Karanlıkdere planlama birimlerinde farklı yetişme özellikleri ve farklı meşcere kapalılığına sahip örnek alanlardan elde edilen toprak nemi ile Radarsat uydu görüntüsü kullanılarak her bir örnek alandan elde edilen geri yansıtım değerleri arasındaki ilişkilerin belirlenmesidir. Artvin-Merkez planlama biriminde kuru ve taze-tazece yetişme ortamları ile düşük ve bozuk orman alanlarında toprak nemi ile geri yansıtım değerleri arasında sırasıyla negatif ilişkiler bulunmuştur (r=-0.85 ve r=-0.73). Buna karşın, orta ve tam kapalı meşcerelerde herhangi bir ilişki bulunamamıştır. Gümüşhane-Karanlıkdere planlama biriminde ise çok kuru-kuru ve taze-tazece yetişme ortamları ile düşük ve bozuk orman alanlarında toprak nemi ile geri yansıtım değerleri arasında sırasıyla pozitif ilişkiler bulunmuştur (r=0.78 ve r=0.83)
