천연동굴의 스포츠관광자원으로의 활용방안에 대하여 모색하였다. 천연동굴의 활용에서 심신수양과 스포츠활동의 장소로서의 가치는 충분히 논의된 바가 있다. 이에 우리나라 전역에 분포하는 다양한 천연동굴의 발굴과 환경보전을 전제로 한 스포츠관광자원으로서의 활용이 기대된다.

Jeju Island is formed by lava flow streams with the Mt. Halla in the center. The Mt. Halla‘s crater or other parasitic volcano produced lava flows creating lava plateau in this area. There are one thousand volcano caves in the world, and 50% of them are located in the west coast of United States. There are 186 volcano caves in Italy, 100 in Mt. Fuji, Japan, and 70 in Jeju Island. Jeju Island‘s east-west axis four sides are world-renown volcano zones with basalt strata that feature low viscosity and fluidity.

The modern people spend more time with heir family on weekends, and this changed the perspective toward leisure and tourism. Along with this, the recognition toward tourism resources have underwent various modifications with the increasing number of family tourists. Caves are categorized as lava tube (formed by volcano activity), lime stone cave(formed by absorption of water into underground level), sea cave (formed by wave erosion) and artificial cave that were made for the fluent traffic activity of railways or roads. Caves manifest characteristics of tourism as a natural resources and tourism as a humanity study, so caves are valuable as a multipurpose tourism resource.

The cavernous rocks of New Zealand can be grouped broadly into two main geologic types-the massive, metamorphosed, Ordovician, Mt. Arthour Marble of north-west South Island, and the stratified, bioclastic, Tertiary Te Kuiti limestones of western regions of both islands. Although much cave exploration has been carried out in both these regions, the principal study so far has involved caves and karst in the central western portion of North Island near the well-known Waitomo Caves, where some 85km of caves have been surveyed during the past 12 years by members of New Zealand Speleolgical Society.

The Bullock Creek Caves are located adjacent to the usually dry river bed of Bullock Creek, which reaches the sea about a kilometer north of Punakaiki. The caves have been comprehensively written up by Rodgers(972). Under conditions of normal water flow Bullock Creek submerges where the stream meets limestone on the west side of their Punakaiki syncline. In flood conditions it overflows the first submergence and progressively floods a series of smaller submergences down valley until it comes to the caves shown on the map. All these with the exception of Wazpretti Cave and Dry Valley Cave are probably more or less flooded during and after heavy rain.(omitted)

The chlorophyta and thebryophyta are became extinct by the shutting out the light and low temperature in caves. Whenever they get the conditions, they grow again immediately. It is necessary to keep the illumination distance over 2m and use the indirect light. The effect of lamp light and temperature is very important in the control of green contamination but the water and moisture in caves are essential factors in green contamination in the show caves. It's better to get rid of green alae and mosses at early stage for the control of the increase of green contamination. They must be isolated completely without the dispersion with moist pieces of cloth or sponge. It is necessary to shut out the cave route periodically for the restoration of cave environments and ecosystem. It's better to use the lamp keeping illumination and restricting the ascension of heat for the control of green contamination.

Lava caves could be useful as outposts for the human exploration of the Moon. Lava caves or lava tubes are formed when the external surface of the lava flows cools more quickly to make a hardened crust over subsurface lava flows. The lava flow eventually ceases and drains out of the tube, leaving an empty space. The frail part of the ceiling of lava tube could collapse to expose the entrance to the lava tubes which is called a pit crater. Several pit craters with the diameter of around 100 meters have been found by analyzing the data of SELENE and LRO lunar missions. It is hard to use these pit craters for outposts since these are too large in scale. In this study, small scale pit craters which are fit for outposts have been investigated using the NAC image data of LROC. Several topographic patterns which are believed to be lunar caves have been found and the similar pit craters of the Earth were compared and analyzed to identify caves. For this analysis, the image data of satellites and aerial photographs are collected and classified to construct a database. Several pit craters analogous to lunar pit craters were derived and a morphological pit crater model was generated using the 3D printer based on this database.
