中文摘要	土地利用变化对陆地生态系统碳循环的影响是当今全球碳循环和气候变化研究的热点。土地利用变化对土壤有机碳含量、组分及稳定性产生影响,从而影响土壤CO_2,进而控制岩溶地质过程的碳汇效应。本文综述了岩溶区土地利用变化对土壤有机碳与岩溶地质过程的影响,阐明了岩溶区土地利用变化对土壤有机碳及其组分影响的过程与机理,土地利用变化对岩溶地质过程影响的土壤CO_2浓度调控机制、水循环影响及无机酸干扰等影响机制。提出了土壤固碳的团聚体归宿和分配,团聚体物理保护机制及钙的化学稳定机制是当前岩溶土壤有机碳深化的方向;土壤CO_2、水循环和无机酸在土地利用变化过程中以何种关系共同影响岩溶碳汇强度;水生光合作用利用DIC形成的稳定有机质与DIC、 AOC通量的关系及其对土地利用变化的响应机理是岩溶碳循环前沿领域;而石漠化治理对岩溶碳循环的影响及相关固碳增汇技术的研究是需要重视的工作。
英文摘要	Effects of land use change on terrestrial ecosystem carbon cycle has been becoming a hot topic research of global carbon cycle and climate change. Land use changes can influence soil organic carbon content,fractions and stability,thus affecting soil CO_2 concentration,and then controlling carbon sink effects of karst geological process. This paper summarizes the effects of land use change on soil organic carbon and karst geological process in karst area,and clarifies the processes and mechanisms of land use change effects on soil organic carbon and its fractions, and the mechanisms of soil CO_2 control,water cycle and inorganic acid disturbance,which influence karst geological process induced by land use change. The aggregate fate and distribution of soil carbon sequestration,mechanisms of physical protection in soil aggregate,and calcium chemical stabilization mechanisms need to be further studied in future. More attention should be paid to how soil CO_2,water cycle and inorganic acid influence karst carbon sink intensity in the process of land use change. The relationships between stable organic matter derived from aquatic photosynthesis by which dissolved inorganic carbon (DIC) was used,and DIC and assimilable organic carbon (AOC) fluxes,and the mechanisms of their response to land use change will become a frontier of karst carbon cycle research. In addition,the influences of rocky desertification control on karst carbon cycle and the technologies for increasing carbon sequestration need to attain more attention.
