Recently many environmental researcher are concerned about the ecological environment and the issue of environmental pollution in cave. In this paper we discuss about air pollution, water pollution, state of water quality, ecological environment and situation of environmental public damage in cave The concerning of air pollution in cave is mainly to the type of secondary contamination, which much is developed in various fields recently. The natural water in the most of cave is no problems but ground water has slitting with natural water during much raining period. The state of water quality is gradually contaminated with artificial environmental pollution, that is, the contents of kinds of Aluminum, Nickel, Copper, Zinc and Calcium are higher than before. On the other hand it is very important things to keep the control of constant temperature, darkness and humidity in cave. The contamination by lamp flora and even black colored contamination are appeared nowadays. The ecological environment in cave destructed by growing of mi coorganism. In fact the internal of cave is shielded with the state of climate of cave external but the environment of internal cave is contaminated, because blowing from external climate state. In addition to environmental pollution caused by carbon dioxide and body temperature of tourists. By the way eco-examination of cave is black color public damage, green color one and white color one has been discovered, so we need to have the situation of demand of environmental reservation alternatives.

The geographic environment means the general state of the environment in the area. Especially, which means the generation cause, the development process of the cave, and the validity of cave development and conservation in the side of the place of the cave. This study put emphasis on lying in which place Hwaam cave in Tong-myon, Chong son-gun, Kangwondo is situated and having in which stand is in comparison with other districts, and how the geological structure which determine the cave forming cause is.(omitted)

Ondal cave is the limestone and the cultural asset cave designated as Natural monument NO. 261. Originally after the caves included in cultural assets separately survey the academic, cultural value of the cave, the result must be the academic basis of the cave.(omitted)

With regard to Jeju Special Self-governing Province's natural-spa tourist spot development project, this paper has investigated the natural environment of Sehwa-Songdang Lave Region. According to this study, the cave consists of many small caverns with poor cave formations. Due to unfavorable climate conditions in the cave, in addition, hydrological environment is also very poor. In terms of vegetation, the cave shows the general vegetation environment of Jeju.

Ondal Cave is important and significant in terms of cultural value and tourism. In addition, there are abundant historical and cultural resources nearby. If the geographical strength is taken advantage of, the cave would evolve into a great tourist destination and natural education spot. This paper has investigated humanistic environment of Ondal Cave in considerations for the surrounding tourism resources. There are abundant tourism resources around Ondal Cave. However, they are rarely connected with each other. In fact, they are very partially interrelated around Guinsa(temple) only. Furthermore, the number of tourists has gradually decreased. Therefore, it‘s required to further develop tourism programs and surrounding tourism resources.

The Environment consolation and the Tour Resources Development of the Cave. The conservation and the development of the cave are complementary to each other. On account of Keepiny on changing, the cave is similar to living thing. Therefore, the cave development mocks the environment changed by the microbes and the mosses by many factors. But if can make the people around the cave get richer and richer by the visitors. If we need to develop some caves, first of all the safety diagnoses must be executed, about the geographic structures, path facilities, electronic ones, and so on.

The cave is similar to living things, because of keeping on changing. The environment in the cave after developing it change because many factors as followings; The microbes and the mosses by visitors and inner facilities will grow in the cave, which makes the ecology a lot of change. The quality of water and air in the cave can lead to the destruction of the ecology by the development. So we do our best to conservate the cave without changing the environment of air, the water and the ground.

To find out the natural environmental characteristics of Ondal Cave, temperature, humidity, wind speed and water temperature have been investigated. When compared to other caves, in sum, Ondal Cave has shown no significant difference interms of natural environment. Inparticular, Ondal Cave was higher than other limestone caves by 1-2$^{\circ}C$ in terms of water temperature due to high inflow of river water nearby.

천연기념물 제219호인 고씨굴은 1974년 일반인에게 개방되었으며 총길이는 3,388m로 이중 620m만 공개되고 있다. 충북 단양에 위치한 고수동굴은 천연기념물 제256호로 총길이는 약 1,700m이며 이중 685m가 1976년 개방되었다. 이들 동굴들은 30여 년 전에 일반인에게 개방되어 활용되고 있으나 이들 동굴 내에 성장하는 동굴생성물들은 오염물에 그대로 노출되어 있다. 이들 동굴의 동굴환경 변화에 대한 연구를 수행한 결과, 동굴 내의 온도와 습도 그리고 이산화탄소의 분압은 계절적 변화가 뚜렷하게 나타난다. 전반적인 이산화탄소 분압은 여름철 성수기가 대체적으로 높은 경향을 보이고 있다. 또한 여름철을 제외한 계절의 경우 관람 후 다음날 개장하기 전까지 동굴 내 대기의 순환에 의한 자정능력이 있으나 여름철의 경우 자정능력을 넘어서게 되어 계속적으로 축적되는 경향을 보이고 있다. 특히, 두 동굴의 이산화탄소 분압은 관람객의 수에 의해 조절되는 것으로 나타난다. 따라서 이들 동굴의 환경을 유지하기 위해서는 일일 관람객의 수를 조절하여야 할 것으로 판단된다.

기존 동굴의 유형분류는 다양성을 갖지 못하고, 성인적, 형태적, 규모적 분류에 국한되어있다. 이러한 분류기준뿐만 아니라 더욱 다양한 동굴의 분류 방법이 필요하다. 이러한 문제점을 해결하는 방법으로 군집분석의 이론적 배경을 살펴보았을 때, 입력변수 선정에 따른 다양한 변수 선정을 통해 다양한 분류 방법이 가능하여 그 유용성이 매우 높다. 실제적으로 동굴의 내부환경, 주변환경 등을 고려한 (1)동굴 규모 및 형태에 따른 수치적 유형분류, (2)동굴외부의 토지이용적 입지특성에 따른 유형분류, (3)동굴의 관계적 주변 입지특성에 따른 유형분류 등이 가능하다.
