为揭示中亚热带植被恢复对土壤磷(P)有效性的影响机制,在湘中丘陵区选取了地域毗邻、环境(土壤、气候)条件基本一致、处于不同植被恢复阶段的4种植物群落--檵木-南烛-杜鹃灌草丛(LVR)、檵木-杉木-白栎灌木林(LCQ)、马尾松-柯(又名石栎)-檵木针阔混交林(PLL)以及柯-红淡比-青冈常绿阔叶林(LAG)为研究对象,设置固定样地,按0~ 10、10~ 20,20~ 30,30~ 40 cm分层采集土壤样品,测定不同季节土壤全磷(TP)和有效磷(AP)含量,比较研究不同植被类型土壤TP、AP含量的差异及其季节变化特征。结果表明:1)不同植被类型同一土层TP含量在各季节总体上随着植被恢复而增加,且LAG与LCQ、LVR(除夏季外)差异显著;季节变...

In order to reveal the influence mechanism of vegetation restoration on the availability of soil phosphorus (P) in the subtropical regions, China, four kinds of plant community were selected as the study objects in central hilly area of Hunan Province, China, which adjacent to each other, had same environment conditions, and were at different stages of vegetation restoration, and which respectively were: Loropetalum chinense-Vaccinium bracteatum-Rhododendron mariesii scrub-grass-land (LVR), Loropetalum chinense- Cunninghamia lanceolata-Quercus fabri shrubbery (LCQ), Pinus massoniana-Lithocarpu...
