Characteristics of Soil Respiration in a Phyllostachys Pubescens Plantation in the Northeast of Subtropics

Soil respiration was continuously measured in situ by using Licor-8150 in aPhyllostachys pubescensplantation, located in Miaoshanwu Forest Ecosystem Research Station in Fuyang, Zhejiang Province. Soil respiration showed an obvious variation in season, which is consistent with the variation of soil temperature, peaking at the hottest month (August) and bottoming out at the coldest month (January). Moreover, the ratios of different soil respiration components to total soil respiration were different, with 25.7% in root respiration, 57.0% in litter respiration and 17.3% in heterotrophic respiration.
