Abstract

주왕산국립공원 탐방로중 가장 높은 가메봉을 대상으로 포유류의 고도별 분포 현황을 분석한 결과 총 22종의 서식을 확인하였다. 해발 200 m에서 800 m 구간을 100 m 단위로 세분화하여 분석한 결과 다람쥐(Tamias sibiricus)가 가장 많은 구간에서 우점종으로 나타났으며, 조사지역내 전 구간에서 서식이 확인된 종은 족제비(Mustela sibirica), 노루(Caproelus pygargus), 다람쥐였다. 확인된 Field Sign을 관찰 지점을 기준으로 분석한 결과, 고도의 증가에 따른 종 및 개체수는 유의적인 관계가 있는 것으로 나타났다(y=-0.0234X+25.552, <TEX>$R^2$</TEX>=0.9296, <TEX>$F_{0.05}$</TEX>(1, 4)=7.71, p<0.05). 그러나 100 m 단위로 세분화한 6구간중 5구간 이상에서 관찰된 9종을 대상으로 분석한 결과Apodemus agrarius(y=-0.034X+25.2, <TEX>$R^2$</TEX>=0.905, <TEX>$F_{0.05}$</TEX>(1, 4)=38.169, p<0.01)와 Sciurus vulgarie (y=-0.0154X+12.819, <TEX>$R^2$</TEX>=0.781, <TEX>$F_{0.05}$</TEX>(1, 4)=14.270, p<0.05) 2종만 유의적 영향을 받는 것으로 나타나 종별 고도에 따른 제한적 분포보다는 주변 식생 현황 및 서식지 구조에 따라 종의 분포가 이루어지는 것으로 판단된다. Box and Whisker Diagram분석 결과200<TEX>$\sim$</TEX>300 m 구간내 탐방객의 출입이 금지되어 있는 자연 휴식년제(Nature Restoration Area) 지역에서의 사분위 편차(<TEX>$Q_U-Q_L$</TEX>)가 가장 적은 것으로 나타났으며, 주변 식생 및 탐방로 형태가 유사한 해발 500<TEX>$\sim$</TEX>600 m 구간에서 가장 광범위한 분포를 보였다. 특히 이 구간내 탐방로 상에서 멸종 위기 야생동물 II인 삵(Prionailurus bengalensis)의 배설물이 집중적으로 관찰되어 이에 대한 연구가 연계되어야 할 것으로 사료된다. The study analyzed the distribution of mammalia per altitude in Gamebong, the highest trail of Juwangsan National Park and confirmed the inhabitation of 22 different species inhabiting in the park. Starting from 200 m to 800 m above the sea level was segmented into 100 m unit. The result of analysis has shown that the Tamias sibiricus is the dominant specie throughout in all segments. Species confirmed to be inhabiting in all segments of research areas were Mustela sibirica, Caproelus pygargus and squirrel. By analyzing the confirmed Field Sign basing from the observation point, it has shown close relations between types of species and population following the increase in altitude (y=-0.0234 + 25.552, <TEX>$R^2$</TEX>=0.9296, <TEX>$F_{0.05}$</TEX>(1,4)=7.71, p<0.05). However, the result of analysis targeting nine species inhabiting in at least five out of six 100 m segmented units has shown that only two species, Apodemus sgrarius (y=-0.034X+25.2, <TEX>$R^2$</TEX>=0.905, <TEX>$F_{0.05}$</TEX>(1, 4)=38.169, p<.0.01) and Sciurus vulgaris (y=-0.0154X+ 12.819, <TEX>$R^2$</TEX>=0.781, <TEX>$F_{0.05}$</TEX>(1, 4)=14.270, p<0.05) were affected by the altitude. Therefore, it is judged that the distribution of species does not follow the altitude variation but follows the food conditions and the structure of habitat. The result of analysis of Box and Whisker Diagram had shown lowest quartile deviation(<TEX>$Q_U-Q_L$</TEX>) in Nature Restoration Area that is located in <TEX>$200{\sim}300m$</TEX> above the sea level, where hikers are prohibited from entering. In <TEX>$500{\sim}600m$</TEX> above the sea level segment that has similar food environment and trail, it has shown the widest distribution. Further research is required on this segment for the excretion drops of Prionailurus bengalensis, a Grade II class of endangered species, were found on the trails.
