To select tolerant species among the Korean major woody plants for restoring disturbed ecosystems by air and soil pollution, we transplanted the seedlings of 56 species in control and polluted sites within Yeocheon industrial complex area, and compared their aboveground growth characteristics such as total branch length, total leaf weight, and maximum photozynthetic rate. Tolerant species growting better in polluted site than in control site was Quercus variabilis, Pinus thunbergii, Q. aliena, P. densiflora, Styrax japonica, Alnus firma, Celtis sinensis, Elaeagnus umbellata, Q. serrata, japonica, Sorbus alnifolia, and Q. acutissimia in local tree occuring within polluted area group (80%), Ailanthus altissima in street tree group (20%), Populus tomentiglandulosa and A. hirsuta var. sibirica in fast growing tree group (50%), Acer ginala and Abies holophylla in late successional tree group (20%), Betulla platyphylla var. japonica, Acer truncatum, A. palmatum, Syringa dilatata, and Rosa multifora in garden tree group (38%), and Q. rubura, and Robinia pseudoacacia in foreign restoring tree group (20%), respectively. The remaining plant species, 37 species (57% of total species), were classified into sensitive species to pollution. Those tolerant species can be utilized for restoration of the degraded ecosystem in this polluted area.

The investigation was made about distribution and ecological characteristics of host plant for Phellinus linteus at habitats in Gangwon-Do. The habitats of P. linteus are the place where the fog is much generated and there is lots of the moisture. The flora of the vascular plants in P. linteus habitats were consisted of 76 taxa; 62 species, 10 varieties and 4 formas of 62 genera of 40 families. The plants of infiltration type were found 70% around P. linteus habitats. This results shows that the natural environments of P. linteus habitat is very stable condition. The categories of vegetation were classified into two types. The host plant for P. linteus appeared 61.6% from Populus tomentiglandulosa. The first type showed up above the sea about 600m and west exposure region. The second type was investigated around the facing north region of the steep slope-land.

In an effort to evaluate the qualities of the unused woods designed for art materials, Yellow pine, Pitch pine, Suwon poplar, Platanus and Cherry grown in Korea has been investigated in the study. Physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods were examined. Among the five species, Cherry wood showed the highest density in green, air-dried and oven-dried conditions. Hardness of Cherry wood was higher than those of Suwon poplar and Platanus. In softwoods, Pitch pine showed greater hardness than Yellow pine. Yellow pine and Platanus had the highest values of wood surface roughness. Abrasion value of cross, radial and tangential sections was the highest in Yellow pine and Suwon poplar. It has been concluded from the experiment that physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods can be used as an indicator of the suitability for woodcraft material.

독일의 산림미학(숲미학)과 영국의 산림디자인 개념에 따르면 우리나라 국립공원 인공림도 단계별로 생태적 복원이 필요하며, 본 연구는 국립공원 인공림의 식생구조를 분석하여 생태적 천이를 유도하기 위한 식생유형별 간벌 밀도 기준을 제시하고자 수행하였다. 국립공원 중 치악산, 속리산, 덕유산, 내장산에 분포하는 잣나무림, 전나무림, 편백림, 은사시나무림, 일본잎갈나무림 등 인공림 8개소와 소나무군집, 소나무-졸참나무군집, 졸참나무군집 등 자연림 3개소 등 총 11개소에 $20m{\times}20m(400m^2)$ 크기의 방형구를 설정하였다. 식생구조 특성을 고려하여 인공림을 천이미발달형, 외래종치수발달형, 천이초기형으로 유형화하였다. 종다양도(H')는 천이미발달형 0.9681~1.1323, 외래종치수발달형 1.0192~1.1870, 천이초기형 1.3071~1.3892, 자연림 1.2202~1.3428로 침엽수 단일수종 위주의 단층구조의 인공림보다 천이초기형 인공림과 다층구조의 자연림의 종다양도가 다소 높았다. 단계별 간벌 밀도는 30~60% 범위로 하되, 천이미발달형은 외래종 우점치가 88~90%로 높으므로 대경목부터 3단계에 걸쳐 간벌하고, 외래종치수발달형은 외래종 우점치가 60~97%로 높고 아교목층과 관목층에 치수가 발달하고 있어 조기에 외래종 치수를 제거하고 1단계 또는 2단계에 걸쳐 간벌하며, 천이초기형은 외래종 우점도가 30% 이하로 자생종과 경쟁하는 외래종을 우선적으로 간벌하고 1단계 또는 2단계에 걸쳐 간벌할 것을 제시하였다.
