Study on Soil Organic Carbon and Its Impact Factors in Rubber Plantation Ecosystem at Different Stand Ages in the Western Region of Hainan
摘要
Abstract
The organic carbon content in the soil profiles of different forest age-class rubber plantations was measured, and the soil organic carbon storage was estimated. The results showed that the content of soil organic carbon (SOC) ranged from 6. 20 to 14, 36 g/kg for rubber plantation ecosystem at stand age of 5 a, IGa, 19a and 33a. The soil organic carbon content gradually decreased with the increasing depth of soil layers, and there was little difference in the soil carbon content in each layer of 0 -60 cm of different stand ages except that of 33a. The carbon content at the same soil layer differed significantly of the rubber plantations with different stand ages, most of organic carbon concentrated in 0 -30 cm soil. The carbon stock of soil organic carbon in 5a, 10a, 19 a and 33a rubber plantation were 76. 85, 74. 48, 81. 74 and 85. 31 l/hm respectively. The soil texture, litter content accumulation and decomposition, forest age size and rubber forest management may be the main factors influencing the soil organic carbon accumulation of rubber plantation.关键词
