北方半干旱区不同岩溶系统的碳循环研究

CARBON CYCLE STUDY OF DIFFERENT KARST SYSTEM IN SEMI-ARID AREA OF NORTH CHINA

中国北方半干旱区存在丛山窄谷、冈山宽谷和孤山溶盆三种岩溶地貌。不同岩溶地貌区的碳酸盐岩溶蚀强度和碳循环强度不同。碳酸盐岩溶蚀量和ＣＯ２吸收量可以用化学热力学过程和化学动力学过程描述。

Three karst landforms distribute in semiarid area of North China,i.e.,cluster peak with narrow valley,gentle peak with broad valley and gentle plainhill.The strength of carbon cycle and limestone dissolution is different in various karst landforms.the carbon dioxide absorption content and limestone dissolution content can be estimated by chemical thermodynamics processes and chemical dynamics processes.
