Comparison of the Structure of Pinus densiflora Community by Soil Depth in Ulsan Grand Park
토양깊이에 따른 울산대공원 소나무군집구조 비교
Abstract
Eleven plots(10m*10m) were established in Pinus densiflora forests and analized in with TWINSPAN and DCA techniques, to study the comparison of the structure of plant community by soil depth in Ulsan Grand Park. As a result of this analyusis, the communities were divided into two groups : Community B which have shallow one. Community A showed climatic climax which have proceeded from Pinus densiflora to Quercus variabilis, Castanea crenata, Platycarya strobilacea, and at last to Carpinus laxiflora. Community A showed climatic climax which have proceeded fro, Pimus densiflora to Quercus variabilis, Castanea crenata, Platycarya strobilacea, and at last to carpenus laxiflora. Community B showed edaphic climax in sere of Pinus desiflora. The diffrernce of the growth of tree height was showed significantly between two communities. The sample tree aged 30 in Community A was 8.50m high and the sample tree aged 35 in Community B was 3.80m high. Community A was better than Community B in soil characteristics and species diversity indicies.
울산대공원 산림의 토양깊이에 따른 식물군집구조를 비교하기 위하여 소나무림에 11개 조사구(10m*10m)를 설정하고 TWINSPAN과 DCN기법을 이용하여 식물군집구조 분석을 실시하였다. TWINSPAN과 DCN분석결과 토심이 깊은 군집(군집 A)과 토심이 얕은 군집(군집 B)으로 분리되었다. 군집 A는 기후극상의 생태적 천이 특성을 보여 천이단계가 소나무$\
