摘要
岩溶作用,作为一种独特的地质过程,不仅塑造了令人赞叹的自然景观,还具有显著的碳汇功能。岩溶作用过程,碳酸盐岩与二氧化碳和水发生化学反应,生成碳酸氢根离子,这一过程不仅在地质上具有重要意义,更在生态和气候层面扮演着关键角色。它通过吸收大气和土壤中的二氧化碳,将其转化为水体中的碳酸氢根离子,进而沉积于地下或被水生植物吸收,有效降低了大气中的二氧化碳浓度。这种自然碳汇过程,不仅有助于减缓全球气候变化,对抗温室效应,而且对于保护和增强生物多样性、维持生态平衡具有深远影响。本文从岩溶碳汇机制过程、岩溶碳汇潜力介绍新词汇“岩溶碳汇”。岩溶碳汇,作为地球自然碳循环的一部分,其潜力的挖掘和利用,对于实现碳中和目标、促进可持续发展具有重要的战略意义。
Karstification is a special geological phenomenon that not only sculpts breathtaking natural landscapes but also plays a significant role in carbon sequestration.The chemical reaction between carbonate rocks,carbon dioxide,and water produces bicarbonate ions.This process absorbs carbon dioxide from the atmosphere and soil,converting it into bicarbonate ions in the water.These ions are then deposited underground or absorbed by aquatic plants,effectively reducing the atmospheric concentration of carbon dioxide.This natural carbon sequestration process is crucial for mitigating global climate change and combating the greenhouse effect.Additionally,it profoundly impacts the protection and enhancement of biodiversity and the maintenance of ecological balance.This paper introduces the term“karst carbon sink,”exploring the mechanisms and potential of karst carbon sequestration.As an integral part of the Earth’s natural carbon cycle,the karst carbon sink’s potential for exploration and utilization holds strategic importance for achieving carbon neutrality and promoting sustainable development.
