Karst Dynamic System and Its Water Resources Environmental Effects

Dear Colleagues,

China is a large karst country, with the karst area accounting for about one-third of the land area. Karstification occurs in an open unbalanced system of cyclic coupling of carbon, water, and calcium (CO₂-H₂O-CaCO₃), which is sensitive to the environment.

The system is defined as a karst dynamic system, which is characterized by its emphasis on the interaction between the various layers of the Earth system. It focuses on the monitoring of material and energy migration and transfer. In particular, karstification absorbs soil or atmospheric CO₂ to form dissolved inorganic carbon, which is discharged to the ocean along rivers. The karst carbon sink effect has been a topic of concern for the majority of scholars. At the same time, owing to the special hydrogeological structure of karst areas, surface and groundwater in karst areas are prone to pollution, water shortage, drought and flood, rock desertification, and other problems; thus, the effect of water resources on karst areas is also a research hotspot today.

This Special Issue aims to gather contributions on the latest scientific research regarding the effects of karst carbon sinks and water resources in karst dynamic systems. This Special Issue hopes to encompass a broad spectrum of topics, including, but not limited to:

• Karst dynamic theory;
• Karst carbon cycle;
• Karst carbon sink and global climate change;
• Ecological carbon sink in karst areas;
• Development and utilization of karst water resources;
• Karst groundwater quality;
• Eco-hydrological interaction;
• Migration and transformation mechanism of pollutants in karst groundwater.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
