摘要：国内外学者对土壤有机碳储量及其影响因素进行了大量研究,取得了一定成果（Eswaran et al.,1993;Scottetal.,2002;王绍强等,2000;解宪丽等,2004）,但由于土壤有机碳库组成的复杂性和影响因素的多样性,目前国内外对土壤有机碳库的储量、
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.
