  • This research was thereby made to study and analysis ecological, landscape, and stability qualities of roadside cut Slopes in expressways and national highways that went through revegetation works. Also, evaluation items and framework for integrated assessment of plant structure and restored state for the maintenance were suggested. Following is the summary of the result. firstly, for stabilization of introduced native plant species on roadside cut slops, assessment on the post-project environmental management through long-term monitoring and maintenance works must be made. It signifies a form of authentic recovery and restoration by the native plants. second, current evaluation framework on the test beds is well managed with clear evaluation standards and table while its method of assessing the post management with only test bed results lacks conformity with this study site. Newly developed evaluation framework on the post construction sites is estimated to be used as assessment standards on any roadside construction sites. Third, after site investigation distinction was observed among different revegetating construction types in the long-term perspective. Due to the different duration time of vegetation state between seed-spray measures(degraded in time) and layer-spray measure(maintained), the use of coarse straw-mat mulching work or Coir net was suggested in long term maintenance of cut slopes. forth, segmentation of post environmental assessment is organized into three large categories of "ecological", "stabile", and "landscape" qualities regarding post restoration quality and stability of slope through native plants with which categories marks 50, 30, 20 points of rates. fifth, components of the post environmental assessment were segmented in twelve categories driving results from former experimental construction and newly focused items on site. In the future, it is possible to propose a customized assessment method considering the location and location of construction work if the research on the application of post-environment assessment methods for road construction surface recording is conducted systematically.

  • To investigate the causes of distribution of Kummerowia striata (Thunb.) Schindl. mostly restricted on the roadside and reclaimed land, plant growth was analyzed under different of tread-pressures: $P_1$(10 times/day, $16.34Kg/cm^2$), $P_2$(20 times/day, $31.52 Kg/cm^2$), $P_3$(30 times/day, $40.79 kg/cm^2$) and the control $P_c$(0 times/day, $3.73 Kg/cm^2$). The matter production in the $P_1$decreased compared with that in the $P_c$, and those in the $P_2$and $P_3$ continuously decreased so that its length growth gradually decreased and, in particular, the growth of leaves and nodule was suppressed. The number of leaves and roots tended to increase in the $P_2$and $P_3$. The water contents of roots following the increase of tread-pressure increased continuously. Following the increase of tread-pressure, T/R ratio and C/F ratio tended to increase. Kummerowia striata showed the highest growth in the $P_c$ and showed 26% relative growth in the $P_1$compared with that in the $P_c$. This plant showed 8% relative growth in the $P_3$, which is excess to the tread-pressure $21Kg/cm^2$, the limit of growth in the plant. Because this plant grew continuously in the P$_3$, the tread-pressure is regarded as an important factor affecting the roadside distribution of this plant.

  • Metcalfa pruinosa was considered to be a very harmful invasive species, due to its high species density in nature and wide range of its host plants. M. pruinosa was distributed in 28 sites among 143 sites. M. pruinosa has wide range and diverse host plants of 52 families 110 species including crop, fruits and forest trees. At present, the identified host plant of M. pruinosa are composed of 62 families and 145 species in total since their first appearance was reported. M. pruinosa was found in roadside 46.7%, followed by forests 33.3% and orchard 20%. Nymphs and adults cause damage to crop and orchard by sucking juice, outbreak of fungi through secretion of wax, and reduction of plant assimilation due to the nectar of nymphs. Also, it reduces the merchantable quality of fruits and thus causes economic damage. It is judged that M. pruinosa has been moved along major road via the traffic vehicles.

  • 도시 강우유출수에 함유된 중금속은 저감시설 내에 축적되면서 기능저하와 유지관리를 어렵게 하는 원인이다. 이러한 문제를 해결하기 위하여 자연적 물질순환과정을 가진 LID 시설이 널리 이용되고 있다. LID 시설로 유입된 중금속은 식물흡입을 통해 밖으로 배출된다. 그러나 식물별 중금속 흡수율이 규명되지 못하여 LID 설계시 식물 종 선정에 어려움을 주고 있다. 따라서 본 연구는 중금속 노출빈도가 다른 LID 시설 내부, 도로변 식물 및 조경공간 식물을 상호비교하여 식물에 의한 중금속 제거특성을 연구하였다. 차량 활동과 접촉빈도가 높은 LID 및 도로변에 식재된 식물류(초본류, 관목류, 교목류)의 체내 중금속 함량은 조경공간 식재 식물체보다 높게 나타났다. 중금속의 체내 축적은 주변환경(유입수 성상, 주변 대기오염 정도 등)의 영향을 크게 받는 것으로 나타났다. 도시 강우유출수에 높은 농도로 함유된 Zn 제거에는 패랭이, 메타세콰이어, 영산홍, 쑥 등이 적정하며, Cu 제거에는 패랭이, 메타세콰이어, 쑥 및 은행나무가 적절한 것으로 평가되었다. Pb 제거에는 벚꽃나무, 메타세콰이어 및 조팝나무가 적정하며, As, Cr 및 Cd 제거에는 패랭이가 적정한 것으로 평가되었다. 식물별 중금속 흡입능력은 서로 다르게 나타났다. 이러한 특성은 다양한 토지이용에서 발생하는 다양한 중금속 제거를 위한 식물 종 선정에 활용될 수 있다.

  • 도시지역의 강우유출수를 관리하기 위하여 자연기반해법의 LID 및 그린인프라 적용이 늘고 있다. 식물이 LID 시설에 적용되는 이유는 광합성을 이용하여 오염물질 저감효율을 높이고, 시설 내부 오염물질 축적을 줄여 유지관리 기능을 향상시키기 위해서이다. 그러나 LID 시설 내부에서 작용하는 식물의 오염물질 흡입능력의 불확실성으로 인하여 식재 선정시 어려움이 많다. 따라서 본 연구는 도로변, LID 시설 및 조경공간에 식재되어있는 식물의 건물률 및 영양물질 함량을 비교하여 오염물질 제거기작을 분석하기 위해 수행되었다. 실험대상인 7종의 초본류, 관목류 및 교목류의 월별 건물률은 60~90% 범위를 보였다. 초본류 몸체 내 TN 함량은 여름철까지 지속적으로 성장하다가 감소하는 추세를 보였다. 그러나 관목류와 교목류는 초봄과 늦여름에 높은 TN 함량을 보였다. 패랭이를 제외한 LID 시설에 식재된 모든 식물에서 높은 TP 함량을 보였다. 이는 LID의 식물이 인 제거에 효율적이라는 것을 의미한다. 식물별 영양염류 함량은 유입수 농도에 영향을 끼치는 도시환경에 크게 의존하는 것으로 나타났다. 따라서 이러한 결과들은 향후 LID 적용 시 식생 선정에 있어 유용한 자료로 활용 가능할 것으로 판단된다.

  • To determine the accumulation and distribution of heavy metals in plants and soils of roadsides, the leaf and bark of Ginkgo biloba and Platanus occidentalis, and the soil were sample from Masan-city roadside and Chinhae forest land in July and November, 1994. The content of heavy metals from all the samples in Masan-city area was much higher than that in Chinhae forest land. The amount of heavy metals in soil was higher than those in plant parts of boty trees. The total amount of heavy metals of the bark was higher than the leaf of G. biloba plants. But that of the bark was less than the leaf of P. occidentalis. Heavy metal content in plants (leaf, bark) varied among elements and collections. The concentrations of heavey metals in both trees were in the order of Zn > Cu > Pb > Cd. The concentrations of the four heavy metals in leaf and Zn in soil in G. Biloba were seasonally changed. Whereas those in P. occidentalis were not significantly changed. And there was a high correlation between the concentrations of Pb and Cu in both trees.

  • Uptake and effects of treated Cd and Pb in rose moss and tomato were studied in pot cultures. Three horticulural plants on the roadside were tested to determine the contents of heavy metals in plant parts. Yields of rose moss were increased by the increase Pb concentrations in soil. Yields of rose moss by Cd treatment were decreased in 1, 000 ppm group, but increased in 500 ppm group. Portulaca grandiflora Hook. proved to be tolerent of Pb and Cd added in soil. Yields of tomato were decreased by an incrase of Pb concentration in soil, and tomato proved to be weak for Pb added in soil. Pb contents in root, stem, leaf, and flower and seed of rose moss were increased by an in crease of Pb concentration in soil Pb content in root was the highest among them. Pb content was the highest in root of tomato, but the lowest in the stem. Among the heavy metal contents metal contents of three horticultural plants collected by roadside, it was the Chrysanthemum which had the highest contents of heavy metal among them. The heavy metal contents in stem were less than in the other plnat parts in all three plants. The number of flowers in rose moss was decreased by an increase of Pb, and Cd concentration in soil, but in tomato it was increased by an increase of Pb concentration in soil. Amount of rose moss seeds which were collected after cultivation was decreased by Pb, and Cd treatment in soil.
