녹화식물의 조기녹화와 자연식생으로의 천이를 빠르게 유도하기 위하여 임도 비탈면에 미생물제재의 사용을 통한 산림토양의 개선효과 및 녹화식물의 초기생육 상태를 분석한 결과는 다음과 같다. 토양의 pH는 미생물 처리구에서 5.69로 많이 중화되어 약산성을 보였고, 치환성 양이온도 대조구에서의 1.59(me/kg)보다 처리구에서 비교적 높은 수치인 5.04(me/kg)로 나타났다. 전질소함량(T-N) 및 유기물 함량도 처리구에서 훨씬 높게 나타나 산림토양의 비옥도가 아주 높게 개선되었음을 알 수 있었다. 미생물제재로 처리된 실험구의 평균 피복율은 대조구보다 2.5배 높게 나타났으며, 각 소형방형구의 발아 평균본수는 미생물 처리구가 대조구보다 2.7배나 높은 발생율을 보였다. 처리구별 목본인 참싸리의 초기 평균 생장량의 차이는 없는 것으로 나타났으며 참싸리의 초장은 발아 초기에 빠른 신장을 보이므로 외래초종과 혼파하면 사면안정 및 경관보전에 유리함을 알 수 있었다. 따라서 현재 외래종 위주의 단순한 종자뿜어붙이기공법의 녹화개념에서 초본 및 목본식물을 혼용한 외래종과 재래종의 사용과 미생물제재를 이용한 미생물 녹화공법의 도입은 산림토양의 개선과 사면안정 및 경관보전 효과를 높이면서 임도 비탈면의 조기녹화에 크게 기여할 수 있을 것으로 기대된다.

This study was launched to verify the effective composition of plant species and its management program most suited for the dredged soiled area near Nakdong River Site 14. The improvement methods of planting base and the composition of plants such as silver grass, reed, and some colonies in aesthetic effect were studied. To search the management methods to decrease the confining pressure risen from the burried seeds which would consequently harm the previously seeded plants, experimental construction process was measured on the site. The purpose of this experiment was to figure out which part of the improvement on the plant base has the most significant effect for the revegetation of infertile, dredged soil, to verify the easily seeded, developing plants among seeded plants, and finally, to find the restoration model using plants near the dredged soil around riverside. 8 seeded plants and 23 invaded species were appeared which among the emerged plants, development of Aster yomena MAKINO, Lotus corniculatus var. japonica Regel, Trifolium repens L, and Dianthus longicalyx Miq were proved to be brought up well. Difference risen from the seed composition were not noticeable until 150day since the germination was proceeded mainly by Aster yomena MAKINO. The experimental plot with dredging sand+organic fertilizer method of construction and dredging sand+soil conditioner method showed most development while the effect of the plot with only the soil base of dredging sand stayed low. Another important method for the management of infertile, dredged soil base would be the removal of disturbing species which the experiment showed the tied relationship between the removal of disturbing species and development of seeding plants. Although this study was carried out focused on the Nakdong River Project, the study suggests the general management program that the removal of disturbing species such as Humulus japonicus Sieboid & Zucc. and Pueraria lobata (Willd.) Ohwi in times around rainy season(60days after seedling) would be effective for the easy growth of revegetation plants.

In this study, we attempted to seek out the ways to recycle fresh root-chips in the slope revegetation works by breaking tree root wastes occurring during the construction works, also to review the applicability of fresh root-chips as the soil media in slope revegetation works. For this purpose, we organized test units in order to investigate on-site applicability of fresh root-chips (broken chips). In order to examine the desirable ration of combining fresh root-chips with the hydroseeding soil media on the cutting slopes, we organized test units depending on the amount of combination. The following is the main experimental results. 1. At first, we analyzed properties of hrdro-seeding soil media and soil of the experimental sites. The overall results demonstrate that all the test units show proper range for vegetation. 2. We believe that the physical properties of soils in the earlier phase of restoration works on the sloped sites are not greatly affected by the fact whether broken chips exist or not. However, as time elapses, broken chips needs to be investigated further on what kind of impact they have on the soil condition. 3. More species are found in the test unit combining broken chips and we believe that it will contribute to blossoming of green plants and ecological succession of neighboring plants. 4. We performed experiment on possibility for fresh root-chips as substitutes for the hydro-seeding soil-media. In the test unit that combines fresh root-chips, its mixture ratio tends to exceed that of the test unit that does not combine fresh root-chips by 5 %. In case of the Thick-Layer-Soil-Media Hydroseeding works, the mixture ratio of the test unit that combines fresh root-chips after 16 weeks exceeds that of the test unit that does not combine fresh root-chips by 75%. 5. From the result of our experiment, it is obvious that the ratio of mixture and the number of emerging species are higher for the test unit combining fresh root-chips than the test unit that does not combine them. In other words, we can replace the hydro-seeding-soil-media with some Fresh root-chips without affecting the physical property of soil.

This study was conducted to find out the physical properties and soil shearing strength reinforcement effect of herbaceous plants for the slope revegetation works. Two native plants(Pennisetum alopecuroides and Miscanthus sinensis) were used for this experiment, because they have excellent seed germination rates without preconditioning, and grow naturally around rivers. To identify the physical properties, the partial dry weight of plants were investigated. To identify the soil shearing strength reinforcement effect, the respective soil shearing strengths of the control soils, Pennisetum alopecuroides, Miscanthus sinensis samples were measured. Also, we did a correlation analysis to examine the relation of shearing strength to plant features. The results are summarized as follows: 1. The average dry weight of Pennisetum alopecuroides samples consists of 52.36% above ground and 47.64% at root. And in dry weight, 78.24% of it's root distributes within 10 cm in soil depth. Meanwhile the average dry weight of Miscanthus sinensis samples consists of 52.91% above ground and 47.09% at root. And in dry weight, 82.95% of it's root distributes within 10 cm in soil depth. 2. The results of correlation analysis showed that for both Pennisetum alopecuroides and Miscanthus sinensis, it could not be said that there was any correlation between shearing strength and plant characteristics, and statistically they were not meaningful. 3. In the shearing strength test with control soils, Pennisetum alopecuroides, Miscanthus sinensis as subjects, the differences in shearing strength measurement results were modest, and the order was shown as control soils < Pennisetum alopecuroides < Miscanthus sinensis, so the soil shearing strength reinforcement effect by the Pennisetum alopecuroides and the Miscanthus sinensis on loamy sand at river banks surface was confirmed.

This study was performed to evaluate the planting properties and root potential of planting block with mixing seeding of herbaceous plants and cool-season grasses in CSG blocks manufactured by cemented sand and materials (CSG) in order to develop environmentally friendly CSG block applied revegetation. Five types of CSG mix designs with cement contents were determined, and the mechanical properties of CSG materials were studied experimentally. To analyze growth properties of plants within CSG block, germination ratio, visual cover, plant height and root potential were measured in four weeks and eight weeks after seeding. The germination regardless mixture seeding of plants and CSG mixproportions started within 4 ~ 7 days after seeding and the germination ratio were in the range of 60 ~ 65 %. The visual cover of kinds of plants evaluated by visual rating system were in the range of 6 ~ 8 in case of seeding the species of cool-season grasses and were in the range of 4 ~ 6 in case of seeding the species of herbaceous plants in four weeks after seeding. The root potential of CSG block with the species of cool-season grasses and herbaceous plants were in the range of $5.7{\times}10^{-3}{\sim}7.7{\times}10^{-3}$ MPa and $2.3{\times}10^{-3}{\sim}6.7{\times}10^{-3}$ MPa in eight weeks after seeding, respectively.

This study was conducted on the field application for a method which is currently used. Although the method was performed with experimental knowledge, this study attempted to approach scientific ways through thirty sets of test-bed and three times monitoring limited by control variations for three months. The factors on previous studies are slope location, slope degree, type (roadfill vs. roadcut), aspect, vegetation cover, species, thickness, vertical length, horizontal length, soil type, elevation, erosion, soil-moisture, soil-hardness, pH, and so on. However, the factors of a suitable and significant level are slope degree, type, aspect, thickness, soil-moisture, vertical length and horizontal length in slope revegetation. the results were as follows : As a result of survey on soil types based on the status before construction, the rate of vegetation cover with non-mesh construction in soil areas was better than the rate of vegetation cover with fiber meshes and wire meshes. The rate of vegetation cover with fiber meshes in weathered rocks was better than using wire meshes. The rate of vegetation cover with the wire meshes in blasted rocks was better than using fiber meshes. Also, the factors affecting the rate of vegetation cover presented the number of appearance species, soil-moisture, thickness. this result presented the more appearance species as a positive role, and the lower soil-moisture and the thicker soil as a negative role.

휴 폐광산 토양에 안정적인 식생도입 시 고농도의 중금속에 의한 독성과 열악한 물리화학적 토양조건은 주요 제한 인자가 됨은 주지의 사실이다. 중금속의 안정화를 목적으로 도입되는 식물의 안정적인 활착을 위해서는 중금속 급성 독성의 경감 및 토양의 물리화학적 특성의 개량이 필수적이라 할 수 있다. 본 연구는 쑥과 잔디를 이용하여 중금속 오염 토양의 안정화할 때 토양개량제로 돈분퇴비 ($75{\sim}225$ Mg/ha)와 도시하수슬러지 ($150{\sim}450$ Mg/ha)의 처리효과를 살펴보고자 포트 (pot) 실험을 수행하였다. 광산토양에 개량제를 처리한 모든 처리구에서 대조구에 비해 쑥과 잔디의 초기 생존율 및 생장량이 크게 증가하였고, 퇴비보다는 슬러지 처리구에서 생육개선 효과가 높았다. 중금속의 식물 체내로의 흡수이행에 있어서는 쑥과 잔디 모두 지상부보다는 지하부에 중금속이 축적되는 양상을 보였고, 슬러지 처리 토양에서 재배된 쑥과 잔디의 체내 중금속 농도가 낮은 것으로 나타나 개량제간 중금속의 생물학적 유효도에 미치는 영향이 다름을 확인할 수 있었다. 토양 개량제 처리에 의해 카드뮴, 아연, 구리 모두 생물학적 유효도가 낮은 형태로 이행하는 것으로 나타났다. 토양 중 중금속의 존재형태에 있어 식물재배 전후의 변화를 측정한 결과 재배 후 토양에서 대체적으로 잔류상 형태, 산화물결합 형태, 및 치환성 형태 함량은 고르게 감소하였고, 유기물결합 형태 함량은 증가한 것으로 조사되었다. 특히 아연의 유기물결합 형태의 비율은 쑥의 경우 7.84% 에서 13.58%, 잔디의 경우 7.84% 에서 14.16% 으로 증가하여 중금속에 대한 유효도가 낮아지는 것으로 나타났다. 본 연구를 통해 퇴비, 슬러지 등의 토양개량제 처리가 그 자체로서 토양중 중금속의 안정화 효과가 있음은 물론 식물안정화를 위해 도입되는 식물의 생육 개선에 효과가 있음을 확인할 수 있었다.

This report is an investigation of the revegetation and secondary succession in the burned area of Mt. Sanseung in Taegu region. The forest fire took place in December, 1977. The survey was conducted eight times, -three times from October 1, 1983 to October 3, the same year and five times from August 10, 1984 to August 15, the same year. The floristic compositions in the sampled sites constituted 25 kinds of vascular plants and 21 kinds in the burned area and the unburned area respectively. The biological type in both the burned and unburned areas was H-D1-R5-e type, which is generally common to other areas (Taegu, Kyungpook, Chung Buk and Kangweon areas). In the burned area dominant species were Carex humilisvar. nana, Arundinella hirata and Quercus serrata and on the other hand, in the unburned area Pinus densiflora, Carex humilis var. nana, Rhododendron mucrfonulatum var. ciliatum and Quercus serrata. The species diversity diversity index(H) and eveness index(e) of the burned area were higher than those unburned area. Degree of succession (DS) was 650 in the burned area at the 6th years after the fires and 962 in the unburned area. THe vegetation of the burned area was slowly recovered as of 1984 compared with each other. According to the analysis of the soil preperties, pH, available phosphorus and exchangeable potassium were increased, but organic matter, total nitrogen and total organic carbon were decreased. It is assumed that these results were due to the forest fire.
