| 中文摘要:某一岩溶区的成景过程与地层、构造等稳定要素及水、空气、气候等变化要素之间相互作用构成一个复杂、动态、多期循环、彼此相似却又差异明显的岩溶成景系统, 并通过不同的成景过程(即成景响应子系统)分别形成既表现出共同的区域、时期、类型等特征, 又具有不同发育特征的各种景观单体(即输出子系统)。其中: (1)地层和构造要素分别构成了成景系统的物质和内动力子系统, 共同从宏观上控制着成景过程的格局、特征(包括方式、强度、幅度等)、极限等。(2)水、空气、气候、生物、土壤等是成景系统相对活跃的外驱动要素, 分别直接或间接为成景过程提供不同的外动力条件, 共同构成成景系统的外部输入和外动力子系统, 对系统的运行、演变起着关键的引导和调节作用, 直接或间接控制着成景过程和特征。 (3)以某一次区域地壳隆升影响程度由强渐弱为时间界限和主线, 将某一成景周期划分为“可溶岩出露和分割(一期区域间歇性构造运动时期)→雏形(区域构造平稳前期)→重要发育和成型(区域构造平稳中期)→继承性改造和发育(区域构造平稳后期)”4个阶段, 分别对应着差异明显的成景特征。(4)区域岩溶作用继续按这4个阶段进行多期周期性循环发育, 期间岩溶区的不同部位(即地表、地下及地表与地下之间)分别进行着不同的成景过程, 并分别形成对应三大类景观, 而它们之间的关系则由各向分散、彼此独立→彼此制约、协同共生演替。 |

| Factors Influencing the Process for Karst Landscape Formation: Stable (Strata and Structure, etc.) and Changing (Water and Air, etc.) Factors |

| Abstract: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. |
