In order to determine ecological niches of forests in Mt. UnJang, the studies were analyzed on the methods of TWINSPAN and DCCA ordination. The results are summarized as follows : Six communities determined by TWINSPAN : Fraxinus mandshurica, Cornus controversa, Acer mono, Carpinus tschonoskii, Carpinus tschonoskii - Quercus variabilis, and Cuercus mongolica community . In the relations of major community and environmental factors, Fraxinus mandshurica, Cornus controversa, and Acer mono community were distributed valley or evenness in the rich of organic matter. Elevation was high comparatively. Carpinus tschonoskaii and Carpinus tschonoskii - Quercus variabilis community were distributed in the low elevation, in rich of MgO and CaCO₃. Quercus mongolica community were distributed in the high elevation, in low of MgO, CaCO₃,. The factors in influencing community distribution were elevation. The importance value in all the quadrats sampled, Quercus mongolica recorded the highest and the next values then came those Cornus controversa, Acer mono, Fraxinus mandshurica, Quercus variabilis, Carpinus tschonoskii, Acer pseudosieboldianum Lindera erythrocarpa, Styrax obassia and Lindera obtusiloba in the orders.

In order to determine ecological niches of forests in Mt. ManDeok, the studies were analyzed on the methods of TWINSPAN and DCCA ordination. The results are summarized as follows ; Four groups were determined by TWINSPAN : Styrax japonica. Quercus variabilis-Quercus mongolica, Carpinus laxiflora and Fraxinus mandshurica-Cornus controversa communities. In the relations of community structures and environmental factors, Stvrax japonica community were distributed in the rich site of magnesium and organic matter, Quercus variabilis-Quercus mongolica community in the low potassium, Carpinus laxiflora community in the low available phosphorus, and the factors in influencing community distribution were elevation. The importance value of Quercus variabilis recorded the highest in all the quadrats sampled and the next values then came those Cornus controversa. Quercus variabilis, Lindera erythrocarpa. Quercus mongolica, f`raxinus mandshurica. C;ornus controversa, Symplocos chinensis for pilosa, Acer mono, Caypinus laxiflora, and Styrax japonica in the orders. The species diversities of major dominant species recorded the highest value in the communities of Quercus variabilis-Quercus mongolica but they lowest value in the communities of Fraxinus mandshurica-Cornus controversa.

본 연구는 순비기나무와 위성류의 삽목증식에 있어서 희토광물계 비료가 발근성적에 미치는 효과를 구명하기 위하여 수행되었다. 삽목시험은 2008년에 수행되었으며, 그 결과를 요약하면 다음과 같다. 순비기나무와 위성류의 발근율, 평균 뿌리 수, 평균 뿌리길이는 희토비료를 처리할 때 무처리 대조구에 비해 증가한 경향을 보였다. 특히, 희토비료 1/2500 희석액의 발근효과가 뚜렷하였다. 이러한 성적은 IAA 발근촉진제에 상응하는 결과이었다. 다만, 위성류의 발근율은 무처리 대조구를 제외한 모든 처리구에서 100%의 발근율을 보임으로써 희토비료 희석액 농도에 따른 발근율의 차이는 없었으나, 발근촉진 효과는 기대할 수 있었다. 희토 희석액의 침지시간에 따른 삽수의 발근성적은 순비기나무와 위성류의 모든 처리구에서 10분 침지한 처리구보다는 60분 침지한 처리구에서 상대적으로 높은 경향을 보였다. 따라서 순비기나무와 위성류의 발근율, 평균 뿌리수 및 평균 뿌리길이 등을 분석한 결과를 기준으로 희토 처리 수준 및 효과를 판단하면, 발근촉진제 처리농도는 희토 1/2500 이하의 저농도에서 60분 침지할 경우 삽수 발근 향상에 충분한 효과가있었다. 따라서 시험에 사용한 희토광물계 비료는 시판되고 있는 IAA 발근촉진제 대체품으로서의 이용 가능성을 확인할 수 있었다. This study investigated the effects of rare-earth fertilizer on the shoot cuttings’ rooting of Vitex rotundifolia L. and Tamarix chinensis Lour. The shoot cutting test was carried in 2008 and the main results are summarized as follows. The rate of rooting and the average roots increased in both number and length when rare-earth fertilizer is treated in V. rotundifolia and T. chinensis in comparison to those of the untreated control plot. In particular, when rare-earth fertilizer is diluted with water 1/2500, the rooting outstandingly increases. This result is almost similar to the effect of the rooting stimulant, IAA. Although there is no differentiation in its rooting rate according to the density, the rooting of T. chinensis shows a 100 percent effect on in the entire treated plot but not in the untreated control plot, so it is usable as a rooting stimulant. As for shoot cuttings`` rooting, depending on the time immersed in diluted solution of rare-earth fertilizer, both V. rotundifolia and T. chinensis showed relatively higher percentages in all treatment plot immersed for 60 minutes than for 10 minutes. In conclusion, considering the results of the rooting percentage and the average number and length of roots of V. rotundifolia and T. chinensis, the shoot cuttings`` rooting appeared higher in percentage when they were immersed in the rooting stimulant for sixty minutes with a lower density than 1/2500. This result shows that rare-earth fertilizer can be utilized as an alterative for IAA rooting stimulants currently available in the market.

Vegetational data from 81 quadrats of Quercus mongolica communities in Mt. Odae and Mt. Jumbong were analysed by applying two multivariate methods : two - way- indicator species analysis(TWNSPAN) for classification and detrended canonical correspondence analysis(DCCA) for ordination. The dominant tree species of Quercus mongolica communities were found in the order of Quercus mongolica, Acer pseudosieboldianum. Tilia amurensis. Carpinus cordata. Acer mono, and Fraxinus rhynchophylla. The forest vegetation of Quercus mongolica community was classified into Quercus mongolica. Quercus mongolica - Carpinus cordata. and Quercus mongolica -Abies nephrolepis groups according to the TWNSPAN. The relationships between the distribution of dominant groups for forest vegetation and soil condition in Quercus mongolica communities were investigated by analysing elevation and soil nutrition gradients. Quercus mongolica group was distributed in the low elevation and poor nutrition area of total nitrogen, Quercus mongolica - Carpinus cordata group was distributed in the low elevation and good nutrition area of Mg^(++) and Ca^(++), while Quercus mongolica Abies nephrolepis group was distributed in =he high elevation and poor nutrition area of Mg^(++) and Ca^(++). The two dominant factors influencing community distribution were elevation and total nitrogen.
