Abstract

Atmosferde biriken karbondioksitin önemli bir kısmı topraktan solunum ile salınmaktadır. Toprak solunumu vejetasyon tipi, toprak nemi ve toprak sıcaklığından etkilenebilmektedir. Bu çalışmada Düzce yöresi Meşe meşcerelerinde farklı vejetasyon tiplerinin (meşe, meşe+gençlik, meşe+fundalık ve fundalık) toprak solunumuna olası etkileri araştırılmıştır. Tüm vejetasyon tiplerinde toprak solunumu 0.40 ile 4.90 g C m-2 gün-1 arasında değişmektedir. Meşe+funda vejetasyonu diğer vejetasyonlardan daha yüksek toprak solunumu gerçekleştirmiştir. Toprak solunumu toprak sıcaklığı ile negatif, toprak nemi ile pozitif ilişki göstermiştir. Sonuç olarak meşe ve funda gibi farklı türlerin oluşturduğu vejetasyon tipi daha yüksek toprak solunumu gerçekleştirmiştir.

Effects of Different Vegetation Types Under Oak Stands on Soil Respiration

Abstract

A significant part of the carbon dioxide accumulated in the atmosphere is released from the soil respiration. Soil respiration may be affected by vegetation type, soil moisture and soil temperature. In this study, the possible effects of different vegetation types (oak, oak + youth, oak + heather, heather) on soil respiration in the Düzce region oak stands were investigated. Soil respiration in all vegetation types varies between 0.40 and 4.90 g C m-2 day-1. Oak + heather vegetation performed higher soil respiration than other vegetations. Soil respiration was negatively correlated with soil temperature and positively correlated with soil moisture. As a result, vegetation type formed by different species such as oak and heather performed higher soil respiration
