Characteristics of Soil Carbon Storage of Abies fargesii Forest in Shennongjia
摘要
Abstract
The natural forest, secondary forest and plantation plots of Abies fargesii were selected in the Shennongjia nature reserve, and soil carbon storage of the three forest types was analyzed. The result showed litter storage of the natural forest, secondary forest and plantation was 97. 15 t·hm-2 , 53. 03 t·hm-2 and 83. 22 t·hm-2 , respectively. The content of the soil organic carbon gradually declined with the soil depth from 0 to 60 cm, and the mean soil organic carbon storage was 53. 31 g·kg-1 for natural forest ＞ 48. 66 g·kg-1 for secondary forest ＞ 47. 62 g·kg-1 for plantation. The total soil organic carbon storage was 271.93 t·hm-2 for natural forest ＞ 219.80 t·hm-2 for plantation ＞ 218.29 t·hm-2 for secondary forest. There was a negative significant correlation between total soil organic carbon storage and Shannon-Wiener diversity index of the shrub and herb layers, and the soil carbon storage from 0 to 40 cm layers was significantly positive correlated with the litter storage.关键词
