为了更好地了解中国亚热带地区将原生林转变为集约经营人工林对土壤碳 (C) 和氮 (N) 动态的影响，我们研究了板栗 (Castanea mollissima Blume) (CF) 和竹 (Phyllostachys praecox C.D. Chu & C.S. Chou) 人工林 (BF) 和邻近的原生常绿土壤中水溶性有机 C (WSOC) 和 N (WSON) 浓度的季节模式。中国浙江省玲珑山阔叶林（NF）。通过去除表层土壤对种植园进行干扰，并施肥和/或覆盖，每年从中收获经济产品（如坚果和竹笋）。我们发现WSOC和WSON有很大的季节变化，并且在温暖的季节比在寒冷的季节低。 WSOC平均浓度的顺序为BF（58.6）>NF（35.1）>CF（18.1 mg C kg-1），这种模式主要是由于冬季BF中的覆盖和CF中表层土壤的去除造成的。土壤总C和N遵循或...
To better understand the impact of converting native forests to intensively managed plantations on soil carbon (C) and nitrogen (N) dynamics in subtropical China, we examined the seasonal patterns of water-soluble organic C (WSOC) and N (WSON) concentrations in soils in Chinese chestnut (Castanea mollissima Blume) (CF) and bamboo (Phyllostachys praecox C.D. Chu & C.S. Chou) plantation forests (BF) and adjacent native evergreen broadleaf forests (NF) in Ling-long Mountain, Zhejiang Province, China. The plantations were disturbed through surface soil removal and were fertilized and/or mulched, from which economic products (such as nuts and bamboo shoots) were annually harvested. We found that WSOC and WSON had large seasonal variations and were lower in the warmer than in the colder season. Average WSOC concentrations followed the order of BF (58.6) > NF (35.1) > CF (18.1 mg C kg-1), a pattern mainly caused by mulching in BF in winter and the removal of surface soil in CF. Soil total C and N followed the or...
