摘要
土地利用变化对土壤团聚体稳定性及其结合有机碳(SOC)有重要影响。采用野外调查与室内分析相结合的方法,对喀斯特峡谷裸地(BL)、草丛(GL)、灌木林(SL)和乔木林(WL)土壤团聚体稳定性与水稳性团聚体有机碳的分布特点进行了研究。结果表明:(1)对于风干性团聚体,BL,GL,SL和WL均以>5mam团聚体为主,不同粒级土壤团聚体含量随粒径减小而降低;对于水稳性团聚体而言则以<0.25mam的团聚体为主,水稳性团聚体含量随粒径减小而呈现先增加后降低再增加的趋势。(2)在0~60cm土层内,风干团聚体和水稳性团聚体平均重量直径(MWD)和平均几何直径(GMD)表现为:WL>GL>SL>BL,分形维数(D)则相反。由裸地向草丛、灌木和乔木林的正向演替,各土层>0.25mm水稳性团聚体(WSA_(0.25))含量、MWD和GMD显著提高,团聚体结构体破坏率(PAD)和分形维数(D)显著降低,显著提高了土壤水稳性。(3)植被恢复后SOC含量增加,乔木林SOC含量平均值分别是裸地,草地个灌木林的2.35,1.37和1.26倍;土壤SOC和各粒级水稳性团聚体有机碳含量均以0~20cm土层最高。(4)水稳性团聚体有机碳含量基本随土壤团聚体粒级的减小而增加,除裸地外均以<0.25mm粒级最大,团聚体有机碳的贡献率均以<0.25mm粒级最大,介于18.85%-41.08%。次生乔木林和撂荒草丛更有利于水稳性团聚体的稳定和土壤有机碳的保护,减少人为干扰、促进植被自然恢复是喀斯特地区生态恢复和防止土壤侵蚀的有效途径。
Land use change has an important influence on soil aggregate stability and aggregate- associated organic carbon.Soil aggregate stability,distribution and accumulation features of aggregate-associated organic carbon were studied under 4 typical vegetation types including bare land(BL),grassland(GL),shrub land(SL) and woodland(WL) in typical Karst Plateau region.The results showed that soil aggregates were dominated by particles with sizes >5mm under dry sieving treatment and decreased with the decrease of particle sizes,while soil aggregates were dominated by particle sizes <0.25 mm under wet sieving treatment and basically presented a trend of increasing firstly,then decreasing and finally increasing along with particle sizes decreasing.Mean weight diameter(MWD) and geometrical mean diameter(GMD) both represent as on both dry and wet sieving treatment,while fractal dimensions(D) on the contrary.In the process of bare land-grassland-shrub land-woodland,aggregate destruction rate(PAD) and fractal dimensions(D) in soil layers reduced significantly,>0.25 mm water stable aggregate(WSA_(0.25)),MWD and GMD increased significantly,which improved water stability significantly.Soil organic carbon(SOC) and aggregate- associated organic carbon showed cohesiveness in surface layer,SOC increased after vegetation restoration and SOC in woodland were obviously superior to other three kinds of vegetation types.Contents of aggregate-associated organic carbon were basically increased with the reduce of aggregates particle sizes,organic carbon were the highest in sizes <0.25 mm except bare land,and contribution rates of aggregate-associated organic carbon were maximum in sizes<0.25 mm,ranging from 18.85% to 41.08%.Secondary woodland and natural grassland were more conducive to aggregate stability and protection of aggregate- associated organic carbon,therefore,reducing human disturbance and promoting to natural restoration is an effective methods to ecological restoration and soil erosion control in karst regions.
