본 조사는 능동산의 산림지 2곳에 대한 목본류의 다양성 양상을 조사하기 위해 12 plot $(100{\times}100 m)$를 설정하였다. 흉고직경 10 cm 이상의 목본류 2,157 그루를 동정한 결과 총 35과 135종이었다. 최소 유의성 차이(LSD)에서 지역 A (울주군 석남사 방향)가 지역 B (밀양시 얼음골 방향)보다 높았다. Shannon-Wiener의 다양성 지수에서 지역 A는 1.822, 지역 B는 2.118로 두 지역간 유의한 차이가 있었다(F=4.12, p<0.05). 곰솔-갈참나무군락이 두 지역에서 우점 하였다. 그러나 지역 A의 중간 고도는 소나무가 우점인 반면 지역 B의 중간 고도부위는 참나무속 식물군락과 서어나무군락이 우점 하였다. 공간 분포 분석에서 능동산의 동서지역의 식물상은 서로 이질적이며 미세기후와 패치(patchy)구조를 나타내었다.

The purpose of the present investigation was to investigate diversity patterns in Mt. Neungdong forested landscape. It was conducted on twelve sloping plots $(100{\times}100 m)$ in the east and west sides of Mt. Neungdong. A total of 2,157 specimins were identified as trees with a diameter at breast height (DBH) ${\geq}$10 em. There were a total of 135 species of 35 families present in both regions of Mt. Neungdong. Least significant differences (LSD) by post hoc analysis revealed that region A had significantly greater densities than region B. Shannon-Wiener functions differed significantly between forests (F=4.12, < 0.05), with region B forest having a significantly higher value (2.118) than region A (1.882). Pinus thunbergii and Quercus aliena were dominant on most plots of both regions, however, the P. densiflora forest of region A was distributed better in the middle plots exposures compared to the opposite ones. Q. aliena, Q. mongolica, and Carpinus laxiflora largely occupied the middle and lower exposures of region B. The spatial distribution in Neungdong's forest was very heterogeneous and reflected by most species as having micro-climate and patchy distributions.

문제 정의

The purpose of the present investigation was to investigate diversity patterns in Mt. Neungdong forested landscape. It was conducted on sloping twelve plots (100x100 m) that was representative of the two separated forests, where the canopy has well developed.
It was conducted on sloping twelve plots (100x100 m) that was representative of the two separated forests, where the canopy has well developed. What is the nature of floristic diversity and species richness patterns generally, and what are the effects of habitat fragmentation? The study was conducted to examine the relationship between floristic diversity patterns and plant life forms.

s: the total number of species in a community, n the total number of individuals observed.

Neungdong forested landscape. It was conducted on sloping twelve plots (100x100 m) that was representative of the two separated forests, where the canopy has well developed. What is the nature of floristic diversity and species richness patterns generally, and what are the effects of habitat fragmentation? The study was conducted to examine the relationship between floristic diversity patterns and plant life forms.
1. Location of the regions at Mt. Neungdong and twelve sites used in this study. Region A: UU, UM, and UL mean upper, middle, and lower sites in the direction of Ulsan-shi, respectively.

데이터처리

Analysis of variance and least significant differences post hoc tests were used with SYSTAT 9 to compare results between forest areas [9, 16].
Mean Jaccard's coefficient of similarity between regions pairs was compared by the two-sample t-test (Table 3). The Jaccard's coefficient showed two distinct groups, although UU1 and UU2 of region A and four middle and lower plots of region B were not well separated from each other.

이론/모형

Environmental species and environmental plot relationships were investigated by detrended canonical correspondence analysis using CANOCO, version 4.0, based on normal data [12].
The Shannon-Weiner index of diversity was used to characterize species richness and abundance [3, 14]. It was calculated as:

성능/효과

A total of 17 species occurred at an abundance of 20 trees per plot or greater in at least one region, and ten species at an abundance of 40 trees per plot or greater, and two species at an abundance of 60 trees per plot or greater (Table 2).
low densities and patchy distributions. In addition there were significant differences between the two forest regions in this study in terms of Shannon-Weiner index of diversity, number of trees, species richness, family richness, species evenness and species composition.
8% of the species variation. P. thmbs'gii was dominant on most plots and they correlated with a combination of substrate variables, essentially presenting level temperature and slopes, while Q. aliens Q. mendie and C laxiHora appeared to be linked to communities in lower altitude on moderate slopes.
2). When this study restricted the species to mare than 5% in dominance (10 species), the first axis explained 12.8% of the species variation. P.
