초록
참나무류 견과는 야생동물들의 주요한 먹이자원이기 때문에 지리산국립공원(피아골, 빗점, 장당골, 뱀사골, 한신계곡, 칠선계곡)에서 2008년부터 3년간 참나무류를 대상으로 견과 생산량을 조사하였고, 지역별, 고도별, 사면별 결실특성을 분석하였다. 결실량의 많고 적음에 따라 조사지별로 다른 결실특성을 나타냈으며, 결실량이 많은 해에는 빗점과 장당골 지역이 가장 많은 결실량을 보였고, 결실량이 적은 해에는 빗점과 한신계곡의 결실량이 많은 것으로 나타났다. 고도별 특성에 따라 결실량이 많은 해에는 1000 m와 900 m, 결실량이 적은 해에는 800 m와 900 m에서 많은 결실량을 나타내었다. 또한 전 조사기간 동안 통해 남사면이 북사면에 비해 많은 견과생산량을 나타내었다.
Abstract
Acorn production of some oak species from 2008 to 2010 in Mt. Jiri national park(Pia, Bitjeom,Jangdang, Baemsa, Hansin, and Chilsun) was measured and compared among study area, altitude and aspect because acorns are an important wildlife food resources. Acorns were produced the most in Jangdang and Bitjeom area at year of good fruiting, and those of Bitjeom and Hansin area were produced the most at bad fruiting year. In terms of altitudinal characteristics on acorn production,acorn production in 1000 and 900 m was the most at good fruiting year, and 800 and 900 m at bad fruiting year showed the most production of acorn. Throughout the study period, acorn production on southern slopes was larger than that of northern slopes
