中文摘要	[目的]通过分析石漠化治理区不同植被恢复年限对土壤有机碳(SOC)及其组分影响,为该地区石漠化的治理提供一定的基础数据。[方法]以重度石漠化土地作为对照,运用空间代替时间的方法,研究了广西壮族自治区平果县果化岩溶石漠化区植被恢复5,10,15,20a后土壤(030cm)SOC和土壤轻组有机碳(LFOC)的变化。[结果]石漠化土地在进行植被恢复后,SOC和LFOC含量明显增加;植被恢复使表层010cm的SOC和LFOC储量明显增加,且随着恢复时间的增长逐渐变大,同时植被恢复对表层(0 10cm)SOC和LFOC储量的影响要远高于下层(2030cm);植被恢复后LFOC储量的增幅远高于SOC储量。[结论]在石漠化区进行植被自然恢复可以有效防止土地石漠化,增加碳的流通。
英文摘要	[Objective]The effects of revegetation on soil carbon(SOC),light-fraction organic carbon(LFOC) was analyzed to provide background data for rocky desertification restoration.[Methods]Sites with severe rocky desertification land was taken as contrast and using space as a substitute for time,SOC and LFOC in sites with 5,10,15,20-year restoration in Guohua karst rocky desertification area of Pingguo County, Guangxi Zhuang Autonomous Region were measured and their changes along revegetation were illustrated.[Results]SOC and LFOC contents increased obviously after revegetation,especially in 010cm soil layer. The increment of surface soil LFOC storage was much higher than that of SOC storage,suggesting that vegetation restoration on rocky desertification land had a large effect on LFOC.[Conclusion]Vegetation restoration can prevent land rocky desertification and increase carbon circulation.
