- W4238676813 abstract "본 연구에서는 경북 청송·영천 지역의 화성암 산지와 의성·안동 지역의 퇴적암(역암 또는 역질사암) 산지에 대한 식생 구조를 비교하여 토지적 지표성을 가지는 식물종과 식물군락을 규명하였다. 두 지역에서 3영급 이상의 삼림식생으로부터 Z.-M.방법에 의해 108개의 식생자료를 획득하여 분석에 이용하였다. 총 85과 239속 444종로 이루어진 25개 식물군락을 구분하였으며, 식물군락 간의 유사성을 분석하기 위하여 출현식물종의 상대순기여도에 의한 PCA(Principal Coordinates Analysis)의 좌표결정법을 이용하였다. 화성암 산지에서는 졸참나무, 신갈나무, 생강나무, 쇠물푸레나무 등 139종의 상대순기여도가 증가하였으나 서어나무와 때죽나무는 감소하였다. 퇴적암 산지에서는 갈참나무, 산초나무, 양지꽃, 붉나무, 방아풀 등의 96종이 증가하고, 신갈나무-생강나무군단의 주요 표징종들인 신갈나무, 졸참나무, 철쭉나무, 고로쇠나무, 쪽동백나무 등은 감소하였다. 뿐만 아니라 조릿대, 느티나무-박쥐나무군락, 들메나무-고광나무군락 등은 결석되어 있음이 밝혀졌다. 결론적으로 의성·안동의 퇴적암 산지의 종조성과 식물군락은 지역의 퇴적암 토지, 구릉성 지형의 인간간섭의 용이성, 그리고 과우기후 등의 독특한 환경조건의 총화로부터 기인하는 왜생(倭生)한 소나무림 및 소림상(疏林相)의 활엽수림으로써 화성암 산지의 삼림식생과 구별되는 지역식생형(regional vegetation type)으로써의 그 독특성이 인정되었다. In order to identify plant species and communities characteristic of lithospheric condition, forest vegetations of igneous(mainly granite) and sedimentary(mainly sandstone) areas in Kyungpook province were compared. We collected 108 phytosociological releves from the older forests over 20 years old. 444 vascular plant species and 25 plant communities were identified. Results of Principal Coordinates Analysis (PCA) indicated that lithospheric conditions and human impacts were the most important factors related to the plant community diversity and species richness. In the igneous rock areas net contribution degree (rNCD) of 139 species including Quercus serrata, Q. mongolica, Lindera obtusiloba and Fraxinus sieboldiana increased and those of Carpinus laxiflora and Styrax japonica decreased. In the sedimentary rock areas, to a lesser extent, 96 species including Q. aliena, Zanthoxylum schinifolium, Potentilla fragarioides var. major, Rhus javanica, and Plectranthus japonicus increased, whereas character species of Lindero-Quercion mongolicae such as Q. mongolica, Q. serrata, Rhododendron schlippenbachii, Acer mono and Styrax obassia decreased, and particularily the species Sasa borealis, the Alangium-Zelkova serrata community and the Philadelphus-Fraxinus mandshurica community were absent. The vegetation of sedimentary rock area is characterized as a regional type shaping dwarf pine forests and sparse and light broad-leaved forests." @default.
