Cave Landscape Protection
With the development of cave tourism, the main problems facing cave landscapes are a series of complicated and interrelated elements affecting the life span of the cave. These elements include the cave’s hydrology, temperature, humidity, air quality, chemical weathering, discolouration and physical damage. Cave landscapes are closed systems and are extremely delicate and fragile. Thorough scientific studies and planning are necessary before opening a cave for tourists. Effective measures must be taken to prevent over-development and unnecessary construction of entrances and exits. Strict controls on the number of tourists, preservation of the geological and hydrological environments, protection of surface vegetation, and prevention of soil erosion, excessive runoff and loss of water are also required. Regular and detailed monitoring of the cave hydrology, micro-climate, air quality, fauna and flora and sedimentation is essential.
