摘要 本文综述了喀斯特地区碳酸酐酶及其与环境的关系和地球化学意义。碳循环通过碳酸酐酶影响水生生态系统。碳酸酐酶是水体碳循环的一个重要因子,是生物地球化学作用的一个重要标志。不同环境条件如水、光、pH值、无机和有机离子等可对碳酸酐酶活性造成不同程度的影响。对于不同岩溶生态系统,植被覆盖率低的土壤碳酸酐酶活性低于植被种类丰富的土壤碳酸酐酶活性。同一类型岩溶生态系统不同岩溶地形的土壤碳酸酐酶活性也不同。研究岩溶地区土壤碳酸酐酶的地球化学作用,可以为岩溶生态系统碳循环的研究提供新的途径和方法,并为岩溶地区石漠化的防治提供理论依据。 The relationship between carbonic anhydrase and environment in Karst area and its geochemical significance are reviewed in this paper. The hydrophilic ecosystem is influenced by carbonic anhydrase, which is an important factor in the hydrocarbon cycle with important bio-geochemical significance. The activities of carbonic anhydrase are affected in various extents by various environmental factors such as water, light, pH, inorganic and organic ions, etc. The activity of carbonic anhydrase in the soils of low vegetation coverage is lower than that in the soils of high vegetation coverage in various Karst ecosystems. Moreover, in the same type Karst ecosystem, the activities of carbonic anhydrase in soils are varied with the various Karst landforms. The geochemistry of the carbonic anhydrase in soils in the Karst area is a new way to study the carbon cycling in the Karst ecosystem and could provide a theoretical basis on the prevention of desertification in the Karst area.
