本文认为洞穴是一种不可再生的自然资源，属于自然遗产。洞穴化过程持续愈长，形态结构愈复杂，相应的资源结构和洞穴环境就愈多样化和分异。洞穴“形态—过程”是洞穴系统内物流、能流运动的轨迹，也是一种“化石”信息流。研究和查明各洞段的形成演变，实为洞穴开发与保护的基础。 This article believes that caves are a kind of non-renewable natural resources and belong to natural heritage. The longer the process of cave-in, the more complex the morphological structure, the more diversified and differentiated the corresponding resource structure and cave environment. The “morphology-process” of a cave is the trajectory of the logistics and energy flow in the cave system, and is also a kind of “fossil” information flow. Studying and ascertaining the formation and evolution of each hole is the foundation for the development and protection of the cave.
