The study for the estimation potential natural vegetation was estimated the occurrence probability distribution using geographic information system(GIS) in Bukhansan National Park. Correlation and factor analysis were analyzed to estimate probability distribution. Coefficients were calculated by logistic regression analysis. Correlation coefficients were significantly at the 0.01 level. Commonality of elevation, annual mean temperature, warmth index and potential evapotranspiration were high value, but topographic index was low value. Communities of over the 0.3 points distribution probability, Quercus mogolica communities were the largest area, 76,940,900 $m^2$, Pinus densiflora communities area was 860,800 $m^2$, Quercus acutissima communities area was 500,100 $m^2$ and Quercus variabilis communities area was 1,000 $m^2$, but Q. aliena, Q. serrata, Carpinus laxiflora and Zelcova serrata communities was not appeared. Therefore, potential national vegetation of Bukhansan national park was likely to be Q. mongolica community, P. densiflora community, Q. acutissima community and Q. variabilis community.

The purpose of this study is on identifying the restoration guidelines of supplementary village grove and villageside forest in case of Neunggil village in Jinan county of Korea. These forests were managed very well before industrialization by village residents in order to obtain fuels and organic fertilizers traditionally. But recently, these forests were abandoned by using natural gas, oil and chemical fertilizer. Therefore, species diversity of these forests was downward and traditional rural landscape was lost. Accordingly, this study suggested the restoration guidelines of these forests through restoring the relationship between man and nature. For this, vegetation map was made by quadrat method. And management guidelines of these forests were suggested by the analysis of vegetation map. Also, for the restoration of supplementary village grove, Miyawiki professor's method of Yokohama university through introducing potential natural vegetation was suggested.

We described the above-ground plant species composition and measured a range of soil physico-chemical properties and the composition and size of the soil seed bank in the remnant natural vegetations on the flood plains of the Han River within Seoul, South Korea. We used analysis of variance and multivariate analyses to analyse the data and S${\o}$rensen's similarity index to compare the composition of the vegetation and seed banks. The soils were circum-neutral and composed of mainly sand and silt fractions with a very limited clay component; a gradient based on sand/clay proportions was identified. The soil seed banks varied markedly between- and within-sites and had much greater species diversity than the above-ground vegetation. Two of the major dominants in the vegetation (Miscanthus saccariflorus and Phragmites australis) were found at very low densities in the seed bank. The site differences appeared to be correlated with the sand-clay gradient, suggesting that the soil properties differentially affected seed inputs into the soil, or that the processes than controlled sediment deposition during floods was also important in differentially affecting seed deposition. Lastly, there was relatively little similarity between the vegetation, dominated mainly by perennials, and the seed bank which contained a relatively large proportion of annuals and biennials. This result suggests that after disturbance caused by flooding there is the potential for many other species to colonize. This may impinge on the regeneration potential of the sites and cause concern for the future conservation of these important remnants of natural vegetation.

Land Use Changes (LUCs) have effects on greenhouse gas emissions and carbon stocks in soil and vegetation. Therefore, predictions for LUC are very important for achieving quantitative targets of $CO_2$ reduction rates. Some research exists on carbon fluxes and carbon cycles to estimate carbon stocks in terrestrial ecosystems in Korea. However, these researches have limitations in terms of helping us understand future potential reductions of $CO_2$ that reflect the influence of LUC. The aim of this study is to analyze the reduction levels of $CO_2$ emissions while considering LUC scenarios that effect carbon fluxes for LCS basic study in the year 2030. In this study, a common approach to model the effects of LUC on carbon stocks is the use of CA-Markov technical process with LUC patterns in the past. Potential reduction of $CO_2$ is calculated by change of land use that contains different soil organic carbon, each land use type, and biomass in vegetation. An IPCC analytical method of natural carbon sink and coefficient results from previous study in Korea is used as a calculation method for potential reduction of $CO_2$. As a result, 12,419 KtC will be reduced annually, which is 8.3% percent of 2005 $CO_2$ emissions in Korea. This will result in 3,226 hundred million won of economic efficiency. In conclusion, conservation of natural carbon sinks is necessary even if the amount of potential reduction change is little.

A survey was conducted on the vegetation of Seogmo island, which is small island (ca. 41 okm2) located about 1km west of Kanghwa island in the central Korea, from Aug. 1983 to May 1984. Based on the field data, actual vegetation map and potential natural vegetation map were made. The island is covered with broad-leaved trees dominated with Quercus variabilis. The dominance diversity curves obtaiend in different associations are grouped in two types, lognormal distribution forms at the undisturbed vegetation and geometric series at the disturbed or rocky sites. It seems that the curves show to us the nature of their ecocline by the hypothesis of some investigators, i.e. Random niche boundary hypothesis, niche preemption hypothesis, lognormal distribution and logarithmic series. Total numbers of vascular plant species of the island were recorded 108 families, 348 genera, 475 species, 73 variaties and 7 forma. And Pte.-Q Index, 0.93, and Fisher's Index, 589.8, were higher than those in neighboring islands.

본 연구는 기존에 건설된 터널 입 출구부를 중심으로 유형과 식생경관 등 주변환경에 따른 식생복구 잠재성을 파악하고 그 결과를 토대로 유형별 상세조사지를 선정하여 각 터널별 개선사항을 도출하고자 하였다. 또한 터널의 구조적 안정성을 유지하면서 경관 및 자연성을 증진시켜 향후 건설될 터널 입 출구부를 자연친화적으로 유도하려는 것이 본 연구의 의의이다. 경부고속도로, 영동고속도로, 중앙고속도로 일부 구간의 터널을 전수 조사하였다. 터널 입 출구부 유형을 갱문형식을 중심으로 면벽형과 돌출형으로 구분하고 식생경관은 층위적 관점과 자연미적 관점을 고려하여 다층동질형, 다층이질형, 단층동질형, 단층이질형, 초지형(나지형)으로 총 5개로 분류하였다. 터널의 구조적 안정성과 식생도입 가능성의 관점에서 식생복구 잠재성을 파악하였다. 구조적 안정성의 요소로는 사면높이와 법면경사를 선정하였으며, 식생도입 가능성은 생육기반 조성의 용이성을 구분하여 각 요소별 정량화 값을 부여하여 다소 변형된 정규 분포로 5개의 등급으로 식생복구 잠재성을 구분하였다. 터널 입 출구부의 유형은 면벽형이 33개소로 돌출형보다 많았으며, 식생경관은 단층이질형, 다층이질형, 초지형, 다층동질형 순이었다. 또한 식생복구 잠재성이 뛰어난 곳은 터널 입 출구부 유형이 모두 돌출형이었으며 이는 돌출된 구조물 위에 성토를 실시하고 성토사면으로 인해 주변지형과 조화를 이루었으며 사면 안정성이 확보된 상태로 생육기반 확보가 용이한 것으로 사료된다. 개선안 도출을 위해 7개의 터널을 상세조사한 결과를 보면, 터널 입 출구부는 지형, 안정성, 공사비, 유지관리 등을 총체적으로 고려하여 결정되어야함에도 불구하고 공사비 및 안정성 등이 우선시 되어 비탈면을 최소화하는 시공이 제대로 이루어지지 못하고 있는 실정이었다. 그 결과, 식생기반이 원활히 형성되지 못했으며 식생기반이 형성된 곳이어도 생태적으로 건전한 식생복구는 이루어지지 못했다. 그러므로 향후에 건설될 고속도로 터널 입 출구부는 입지 및 자연 생태 조사를 사전에 실시하여 설계에 반영하도록 하고 훼손면적 범위를 최소화하는 터널 입 출구부 유형을 지역의 특성에 맞게 적용되어야 할 것이다. 또한 안정성을 기초로 한 적극적 식생복원 기법을 도입하여 생태적으로 건전하고 지역의 특색에 맞는 터널 건설이 되어야 할 것이다.

Results from study on physiological responses to $SO_2$ of Quercus spp. selected for restoration of vegetation damaged by air pollution in the field study were as follows. Tolerance of Quercus aliena, Q. acutissima and Q. mongolica used in this study to $SO_2$ was higher in that order and tolerance of these plants to $SO_2$ was high comparatively among trees composing of major forest vegetation of Korea including natural forests and plantations. Stomatal resistance of these plants was increased after exposure to $SO_2$ and range of increase was different among species. From discrepancy between order of tolerance to $SO_2$ and range of increase in stomatal resistance, we were estimated that resistance mechanisms of Quercus spp. were different among species as mechanism originated in avoidance and resistance, respectively. Water potential of plant leaves reduced after exposure to $SO_2$, degree of reduction accorded with order of tolerance to $SO_2$. Reduction of water potential of plants after exposure to $SO_2$ was initiated before appearance of visible damage in plant leaves and water potential of plants exposed to $SO_2$ of low concentration, in which plants were not showed viaible damage was also reduced.
