根据近年作者及国内相关研究数据,分析茶园生态系统中各子系统Al的库容、循环流量和速率,提出茶园生态系统Al的生物地球化学循环模型.生态系统Al的惰性库、调节库和活动库之比为10 000∶200∶1;Al的内外循环量都很大,分别达51.89 kg.hm-2.a-1和33.48kg.hm-2.a-1;调节库和活动库Al的周转速率非常快,年更新率分别达0.34%和55.48%,体现了其他生态系统所没有的特别高的Al循环特征;茶园Al循环导致了土壤的加速酸化、无机态Al向有机结合态Al的转化和生态系统中有机结合态Al的不断积聚.

Based on the data from recent researches,the rates of pool,flow and turnover of Al in the subsystems of tea garden ecosystem were analyzed,and a model on the biogeochemical cycle of Al in the ecosystem was conceptualized.Results indicated that the capacity proportion of the inert pool,regulate pool and active pool of Al in the ecosystems was 10 000∶200∶1.As prominent characteristics,the biogeochemical cycle of Al in tea garden ecosystem is especially larger and rapider than in other ecosystems.The flows of in-and-out cycle of Al are of great quantity,which amount to 51.89 kg.hm-2·a-1 and 33.48 kg·hm-2·a-1,respectively.And the turnover rate of Al in the regulate pool and active pool are both rapid,leading to a fast yearly replacement rate of Al in the regulate pool（0.34%）and the active pool（55.48%）.Such biogeochemical cycle of Al would lead to the acceleration of acidification in the soils,to the transformation of Al from inorganic compound form into organic compound form,and to the continuous accumulation of Al in organic compound form in tea garden.
