摘要：Information on soil organic carbon (SOC) content and stocks is not available in coastal shelter forests, East China, although a large area of forests has been established there in the past 30 years. Dawn Redwood (Metasequoia glyptostroboides) is one of the most commonly tree species for shelter plantation in eastern coasts of China, but it is unknown on the temporal distribution of SOC content and stock in the M. glyptostroboides plantations. In this study, SOC contents and stocks, and soil properties were determined in an age-sequence (23, 27, and 33 years old) of M. glyptostroboides plantations in Shanghai, East China. SOC content and stocks increased gradually with the increasing stand age, and the total SOC stocks in the depth of 0-100 cm increased by 53.20% with stand age from 23 to 33 years stand. Meanwhile, SOC showed good relationships with soil physical properties (such as soil particle composition) and chemical properties (such as soil nitrogen and potassium concentrations). Our results indicate that afforestation with M. glyptostroboides can promote SOC content and stocks and improve nutrient conditions in coastal lands, and provide data for estimating ecosystem carbon stocks of coastal shelter forests in China.
