摘要

摘要: 岩溶作用通过碳酸盐岩溶解时消耗大气或土壤CO2成为重要的碳汇过程。本文首先简要介绍了定量评价岩溶作用及其碳汇强度的水化学径流法和碳酸盐岩溶蚀试片法及其优缺点,即水化学径流法仅适用于边界清楚且为全排型的流域,而试片法仅适用于土壤中不含碳酸盐矿物的条件。继而推导出了岩溶作用及其碳汇强度计算的“入渗-平衡化学法”(或称“潜在最大溶蚀法”),该方法的优点在于只要知道了相关地区的基本气候资料,如温度、降水和蒸发蒸腾数据,即可计算出该地区的岩溶作用及其碳汇强度。

Abstract: Karst process is an important mechanism for carbon sink because dissolution of carbonate rock consumes atmospheric and/or soil CO2. This paper firstly introduces the methods of solute load and carbonate-rock-tablet test to calculate the intensity of karst process and the relevant carbon sink, and discusses the advantage and disadvantages of these methods (i.e., solute load method is only valid for the case where there is well-defined boundary and closed discharge of catchment, while carbonate-rock-tablet test is only valid for the case where there is no carbonate in the tested soil), and then put forward the method of maximum potential dissolution. With the method of maximum potential dissolution, the intensity of karst process and the relevant carbon sink can be obtained only if air temperature, rainfall and evapotranspiration are known in an area.
