'Gu Maig(瞿麥)' is one of the Chinese crude drugs used mainly to cure a diuretic, gonorhoea and menostasis, etc. With regard to the botanical origin of 'Gu Maig', it has been considered to be Dianthus spp. of Caryophyllaceae, but there has not been studied pharmacognostically. To clarify the botanical origin of the "Gu Maig", the morphological and anatomical characteristics of the leaves and stems of Dianthus species growing in Korea, i.e. D. sinensis, D. superbus var. longicalycinus, D. repens, D. morii, D. superbus var. speciosus were compared. As a result, it was determined that 'Gu Maig' was the whole plant body of Dianthus sinensis and D. superbus var. longicalycinus.

During the period of 1975-76, a survey was carried out to find out zinc indicators in the natural vegetation in Korea. The symptoms fo chlorosis were observed in flowering plants in the areas of zinc outcrop of Wolgok-A, Seokgok-9, and Sowolgok. Although 28 species were found to be chlorotic, the total quantity of chlorotic foliage observed was small. Reasons for chlorosis in the areas of zinc are deposits is considered as effects of zinc, lead, copper and calcium ions. Sedum sp. and Dianthus sinensis were confined to soil containing more than exchangeable zinc of 30 ppm and to accumulation in the plants contained at least 1,300-14,000 ppm of zinc. Therefore Sedum sp. and Dianthus sinensis might be used as zinc indicators in Korea.

Research was initiated to investigate a vegetation characteristics of the winter season by seeding periods. 3 seeding periods (Mid-December seeding plot, Late January seeding plot and Early March seeding plot) and 3 zones (the top zone, the middle zone and the bottom zone) in each plot were treated with 3 replications on the experimented slope. Data such as vegetation coverage (%), soil hardness (MPa), temperature ($^{\circ}C$) and moisture (%) content were analyzed. The vegetation coverage was high in Early March seeding plot, medium in Mid-December, and low in Late January seeding plot. Early March seeding plot was effective in moisture content, soil hardness, and temperature for the growth of vegetation when compared to Late January seeding plot and Mid-December seeding plot. From the standpoint of coverage ratio of plant species, the coverage of Dianthus sinensis and Albizzia julibrissin were high in the Late January seeding plot whereas the coverage of Lotus corniculatus and Cool-season turfgrass were high in Early March seeding plot. These results indicated that the high vegetation coverage of Dianthus sinensis and Albizzia julibrissin in Early March seeding plot was caused by scarification during winter season. There was no difference observed in plant height regardless of seeding periods except in early surveying time of May and June after seeding. As far as each zone of the plot was concerned, the vegetation coverage was high. in the bottom zone, medium in the middle zone and low in the top zone. The bottom area of the experimented slope was high in moisture content when compared to the middle zone and the top zone.

전국의 16개 휴 ${\cdot}$ 폐광 지역에서 토양중 중금속함량과 식생조사를 실시한 결과를 요약하면 다음과 같다. 조사 휴 ${\cdot}$ 폐광산 대부분의 경우 피복식물이 없는 나대지로 존재하고 있었고 유기물함량, CEC 등이 낮은 값을 가지고 있는 등 대체로 척박한 토양조건을 가지고 있었으며 특정 중금속으로 인한 오염의 정도가 토양환경보전법상의 우려기준과 대책기준을 초과하는 지점도 있었다. 식물종들의 분포를 조사한 결과 목본은 소나무, 아카시나무 등이, 초본은 쑥과 억새의 출현빈도가 높았다. 쑥은 지상부에 Zn과 Cd를 각각 1,191, 26.35mg/kg을 함유하였고, 패랭이꽃은 Cu를 405mg/kg 함유하여 체내 농도가 가장 높은 것으로 조사되었다. 체내 중금속함량, 건물생산량, 생육기간등을 고려할 때 쑥, 억새, 달맞이꽃등이 토양정화식물로서의 가치가 있다고 생각된다. 앞으로 쑥을 비롯한 내성이 있는 식물종에 대한 조사는 물론 생리적 특성, 토양조건, 기후조건 등에 대한 지속적 연구가 뒤따라야 할 것으로 생각된다.

Research was initiated to investigate a vegetation characteristics of the species of ground cover plants mixed with herbeceous and woody plants on a cut slope. 4 different ground cover plants (Miscanthus sinensis var. purpurascens, Pennisetum alopecuroides, Festuca arundinacea and Zoysia japonica) were seeded at the same rate of $10.0g/m^2$ with herbaceous plants (Lotus corniculatus var. japonicus, Dianthus sinensis, Aster yomena, Chrysanthemum zawadskii and Coreopsis drummondii L) at the total seeding rate of $7.5g/m^2$ and native woody plants (Lespedeza bicolor Turcz, Indigofera pseudo-tinctoria and Albizzia julibrissin) at the total seeding rate of $7.5g/m^2$, respectively. This experiment was treated with 3 replications on a randomized block design. Data such as surface coverage rate(%), the germinating number, plant height and visual quality were analyzed. There were no statistic differences observed in the soil hardness and the soil moisture content while a significant difference was observed in the surface coverage rate and the germinating number. The surface coverage rate and the germinating number were significantly high in the Pennisetum alopecuroides plot when compared with the Miscanthus sinensis var. purpurascens plot, the Festuca arundinacea plot and the Zoysia japonica plot, respectively from the viewpoint of ground covers. Especially, the surface coverage rate was considerably low in the Festuca arundinacea plot. However, the surface coverage rate and the germinating number were no statistic differences observed in this treatment from the viewpoint of herbaceous and woody plants. Also, both of the plant height and visual quality were high in the Pennisetum alopecuroides plot when compared with the Miscanthus sinensis var. purpurascens plot, the Festuca arundinacea plot and the Zoysia japonica plot, respectively. We concluded that Pennisetum alopecuroides was the optimum plant from the treated ground covers mixed with native woody and herbaceous plants for the balanced emergence from the viewpoint of the ecological slope vegetation.
