摘要

[目的] 揭示不同恢复年限的天然草地土壤碳库动态变化及其剖面分布特征

全面认识和理解天然草地恢复下土壤有机库、无机碳库的动态特征。[方法] 采用野外调查与室内试验分析相结合的方法

以农田为对照

对黄土丘陵区不同恢复年限(11

22和35 a)的天然草地土壤有机碳(SOC)、无机碳(SIC)、总碳(STC)的动态变化及其剖面分布特征进行了探讨。[结果](1)天然草地恢复过程中表层(0-10 cm)SOC含量随植被恢复年限显著增加

下层(10-100 cm)SOC含量随植被恢复年限变化不明显;0-100 cm土层SOC储量呈先减少后增加趋势

但仍未达到农田SOC储量的水平。(2)天然草地0-20 cm土层SIC含量呈相对脱钙现象

0-100 cm土层SIC库储量约为SOC库储量的2.7~4.5倍。土壤无机碳库随植被恢复年限的增加无明显变化

但SIC的剖面分布深度发生改变。(3)土壤总碳库随恢复年限增加无明显变化

0-100 cm土层SIC储量在STC库中所占比例约为75.6%~86.0%。[结论] 短时间内天然草地的土壤碳汇效应并不明显

碳库增汇效应需要长期的过程。

Abstract

[Objective] This Paper aimed to investigate the dynamic variation and distribution of soil carbon of natural grassland under different restoration years in order to understand the dynamic characteristics of soil organic and inorganic carbon pool.[Methods] Using field survey and laboratory analysis method

this study analyzed the dynamic variation of soil total carbon of natural grassland under different restoration years(11

22 and 35 a) in loess hilly region.[Results] Soil organic carbon(SOC) content in the 0-10 cm soil layer surface was increased significantly with the increase of restoration years

while no evident changes were found in the 10-100 cm soil layer. Variations in average soil organic carbon storage of natural grassland at 0-100 cm soil depth decreased initially and then increased with the increase of restoration years. However

it had not reached to the level of farmland. Decalcified phenomenon existed in 0-20 cm soil layer. Soil inorganic carbon(SIC) storage was 2.7 to 4.5 times larger than soil organic carbon storage in 0-100 cm total soil layers. No significant variations occurred in total soil carbon storage as the restoration years increased. Soil inorganic carbon storage accounted for about 75.6% to 86.0% of soil total carbon storage in the 0-100 cm soil. The SIC pool was an important factor that influenced soil total carbon pool in the study area

which also maintained the dynamic balance of soil carbon pool in this region.[Conclusion] In the semi-arid environment of the Loess Plateau

soil carbon sequestration effect in natural grassland is not obvious and the improvement of soil carbon pool is likely to require a considerably long period of time.
