 Study of the Carbon Stocks of Soils Under Five Kinds of PlantationsTao Zhang, Fuxu Wan and Zhengxin Tan Asian Agricultural Research, 2015, vol. 07, issue 04, 3 Abstract: Based on the field data and laboratory analysis, we studied the soil organic carbon storage and vertical distribution features about five kinds of plantations in Xuyi, and the results showed that soil carbon density in the five forest types changed greatly, with a range of 0.8-3.04 kg/m2 for five soil layers. Furthermore, soil carbon density decreased generally with the depth, as well as carbon content. In the whole soil profile, the range of carbon density in these five forests was from 4.79 kg/m2 to 5.62 kg/m2. However, 60% carbon was concentrated in 40 cm depth of soil. The calculated result of soil organic carbon reserve was as follows: Cupressus lusitanica (50.264 t/hm2), hackberry (47.859 t/hm2), Populus L. (53.216 t/hm2), Red bayberry (49.581 t/hm2), Amygdalus persica L. (58.202 t/hm2), with the average storage of 51.824 t/hm2, lower than the national average level, so, people should pay attention to the artificial forest tending and management. According to the above analysis, this paper concluded that the afforestation was the effective measure for increasing the soil organic carbon accumulation, and the effects of planting the indigenous tree species Cupressus lusitanica and Amygdalus persica L. were best.
