| Factors Influencing the Process for Karst Landscape Formation: Stable (Strata and Structure, etc.) and Changing (Water and Air, etc.) Factors |
| Interactions among landscape formation processes, stable factors such as strata and structure, and dynamic factors such as water, air, and climate in a specific karst area, form a complex, dynamic, multi-period cyclic system for karst landscape formation (SKLF). These periods exhibit similarities and differences, contributing to the unique characteristics of each cycle. Different processes for karst landscape formation (PKLF), represent the response subsystem of landscape formation, resulting in the formation of various landscape elements (i.e., output subsystems). These elements exhibit characteristics of certain regions, periods, and types, while also displaying distinct development attributes. Among them: (1) strata and structural factors constitute a material and endogenetic force subsystem impacting SKLF, jointly controlling the pattern, characteristics (e.g., mode, intensity, and amplitude), and limits of the PKLF at a macroscopic level. (2) Water, air, climate, biology, soil, and other factors are relatively active external SKLF driving factors that directly or indirectly provide various external dynamic conditions for the PKLF. These factors constitute an external input and exogenous force subsystem of the SKLF. They critically guide and adjust SKLF operation and evolution by directly or indirectly controlling PKLF features. (3) Considering the degree of influence of regional crustal uplift (ranging from strong to weak) as the time limit and the main line, a single cycle of karst landscape formation can be divided into four stages: soluble rock exposure and segmentation stage (phase-I intermittent regional tectonic movement period), embryonic stage (early stage of stable regional geologic structure), important development and formation stage (middle stage of stable regional geologic structure), and inherited transformation and development stage (late stage of stable regional geologic structure). These features correspond to the distinct characteristics of karst landscape formations. (4) Regional karstification continues to develop in multi-stage cycles incorporating these four stages. During this process, different parts of the karst area (surface, underground, and between surface and underground) undergo various PKLF activities, leading to the formation of three corresponding landscape types. Over time, the relationships between these landscape types from being dispersed and independent to interdependent, where they restrict and support each other in synergistic symbiotic succession. |
