We report the status of wetland vascular plant species in Korea including the whole peninsula and its adjacent islands. This analysis was based on database from our previous categorized list. In all, 4,050 taxa have been reported, including 3,769 native and 281 naturalized. Of these, 479 taxa (12%) are considered as wetland vascular indicator species: 240 obligate wetland plants (OBW) and 239 facultative upland plants (FACW). Approximately 31% of those 479 taxa, i.e., 149 taxa, are labelled as aquatic macrophytes. Wetland plants, mostly herbaceous but some woody, inhabit aquatic bodies and wet meadows. Except for two OBW and six FACW taxa, the rest of the plants are summer-green only. The information provided here is valuable for making assessments of wetland ecosystem health, as well as for developing management plans to preserve and restore wetlands and their resident plant species while also creating artificial wetland environments.

A wetland is an ecosystem which is the most useful and highly-energetic transition area. This study has been carried out to develop the wetland function assessment methods and apply on the natural wetlands (Mul-young-ari wetland in Jeju-island and Bangdong wetland in Taejon Metropolitan city) using RAM (Rapid Assessment Method). The RAM is useful method for assessing the wetland functions in terms of general functions acquired by once or twice onsite surveying. Eight functions of 2-12 variables each are analyzed for assessing the wetland functions. The results are as follows : 1) The conservation values of two wetlands are "High". 2) In Mul-young-ari wetland, such functions as groundwater discharge, floral diversity and wildlife habitat, shoreline/stream bank protection are relatively high, but some functions such as flood/storm water storage, aesthetics and recreation are "Moderate" - "High". 3) In Bangdong wetland, such functions as floral diversity and wildlife habitat, groundwater discharge, flood/storm water storage, aesthetics and recreation are high, and another functions are "Moderate" - "High". The taxonomy of this study stems from assessing functions of inland wetlands using indices of RAM. So It is needed that consequent studies are to be performed with verifying the variables and indices.

Wetlands considered to be an important natural resources because they provide biodiversity and habitat for species to breed and survive. In this regard, many countries in the world provide wetlands and have policies and laws to protect them. In Korea we hosted RAMSAR COP-10 at Changwon in 2008 representing Korea's endeavor to wetland protection. But, in the process of development Wetlands are easy target to be lost due its easy access and the laws and regulations to protect them are relatively weak. Thus, this research focused on the introduction of No Wetland Loss(NWL) and we can achieve wetland protection in the economy market ways. Thus, NWL should consider 1) a clear definition of NWL and harmony and consensus of introduction of NWL, 2) considering most wetlands be private we need a financial support for securing wetlands, 3) inventories for wetlands in Korea, draw a line of demarcation, technic to evaluate wetlands, 4) wetland restoration considering function of ecosystem not total amount of wetlands. Wetland protection should be a part of Basic Law of Water Management which in its progress and we need further studies on wetland protection because of watershed management, deserted agricultural paddies, etc.

Long-term water treatment performance analysis was conducted for the constructed wetland treating agricultural tailwater. Studied wetland was established in 2001 and operated from June, 2002 to November, 2010. Wetland vegetation cover was shown over 90 % coverage after 2005. According to vegetation development, accumulation of sediment nutrient was observed; Organic Carbon, T-P and T-N. In addition, DO concentration and temperature was decreased in the constructed wetland output. An infiltration rate also significantly decreased due to compaction of wetland soil. A runoff coefficient was increased due to the low infiltration rate after 2005. A T-N, TSS and Chl.a removal rate was maintained constantly. However, the T-P removal rate was slightly decreased along to wetland operation because low DO concentration could increase elution of phosphorus from sediment. After constructing open water, the T-P removal rate was increased. This is because open water could accelerate the reaearation process. Consequently, over three years of vegetation development could be helpful for wetland performance. In addition, DO concentration is important factor to maintain the T-P treatment.

The purpose of the present study is to develop ecological experience learning program for the wetland so that elementary school students can recognize the significance and values of wetland and have the attitudes to protect it through their ecological experience learning, and investigate changes in elementary school students' perception for wetland. The experimental class was composed of 26 elementary school students and took the ecological experience learning. The comparison class was also composed of 26 students who took theoretical learning for wetland. It was found that knowledge and attitudes for wetland of the experimental class were significantly high not only in the knowledge area but also in the affective area than those of the comparison class. And it was found that interest and curiosity into wetland were elevated also in the results of the qualitative evaluation, suggesting that we could get the effect of ecological experience learning. Therefore, it is thought that above all, more experience learning programs for wetland are needed to develop for elementary school students' right view of nature and minds to love it by continuously finding and providing materials of experience learning like those of this research in the future.

The standard design methodology was suggested to construct wetland system for reducing non-point source pollution from Saemangeum reclaimed paddy land. To set for the design flow and concentrations, runoff and water quality survey were conducted during the irrigation period in 2008 at Gyehwa reclaimed paddy land located at near Saemangeum lake. It is rational that 1ha is the optimum constructed wetland size. To meet this size, the moderate drainage area of reclaimed paddy field was 50ha under the conditions that rainfall is 30mm, average runoff coefficient is 0.83, and runoff capture ratio is 0.6. At these condition, the runoff volume from 50ha was 10,520 $m^3/d$ including base flow during irrigation period. To select the optimum wetland system, several case studies were conducted by focusing on the tidal reclaimed land areas having wetland systems in Seokmun. Pond-Wetland system was selected as the standard model because of showing the highest reduction efficiency. Single variable regression equation were delivered to estimate effluent water concentrations from the designed wetland by using long-term monitoring data from the Seokmun experiment site. The effluent concentration from the designed wetland using these equation were showed moderately range.

This study was conducted to analyze the variation of hydro-geomorphological environment along Baekgok wetland, which experiencing periodical inundation, in that water-level fluctuation of reservoir caused by irrigation. Since the field data is unavailable, modeling techniques, involving models such as HSPF and TELEMAC-2D, have been applied to simulate hydrological cycle in watershed and hydrodynamics in channel scale. The result of simulation indicates that the water-level of reservoir determines both the water surface extension and water depth in the wetland. Furthermore, it also shows that water-level functions as a spatial limit factor for a fluvial environment and woody vegetation such as willow. The fact of which the scale of water-level fluctuation being larger than an average topographical relief along the wetland can explain the result. While the water-level kept high, the wetland is submerged and waterbody becomes lentic. In contrast, while the water-level is lowered, fluvial phenomena of which being dependent on flow rate and channel shape become active. Hence, the valid fluvial process is likely to take place only for 4 months annually just near the channel, and it advances to a conclusion expecting a deposition to be dominant among the wetland except for such area. It is anticipated that such understanding can contribute to establishing plans to preserve the geomorphological and ecological value of the Baekgok wetland.

The researcher noted the fact that wetland users are more and more diversified while people are more conscious of their ecological importance. Wetlands tend to be very sensitive in ecological terms, and therefore, they can hardly accommodate their users' needs indefinitely. With such basic perception in mind, the purpose of this study was to survey wetland users' eco-consciousness, determine their traits, analyze the corelation between their traits and preferences of wetland amenities, and thereby, provide the data useful to planning of an effective wetland management policy. To this end, the researcher sampled nation's largest wetland, Upo Marsh located in Changnyeong for a questionnaire survey. Wetland users' eco-consciousness was measured, using Dunlap's NEP (New Ecological Paradigm) approved by many researchers. Wetland users' preferences of the wetland amenities were measured, centered around 11 amenity types observed commonly at the domestic wetlands. As a result of the survey conducted in October, 2012, a total of 228 effective samples were acquired. Wetland users' eco-consciousness was higher than normal, scoring 3.45 on the 5-point scale consisting of 5 sub-scales. In particular, users were more conscious of 'the possibility of an eco-crisis,' while being less conscious of 'ejection of exemptionalism.' As a result of classifying the users into 3 sub-groups in reference to their eco-consciousness and analyzing their preferences of amenities comparatively, significant differences were found in all 3 sub-areas. In particular, the sub-group most eco-conscious tended to prefer the learning amenities, but the least eco-conscious sub-group tended to prefer the utilities. As a result of the post-hoc test, it was found that most and normal eco-conscious sub-groups were more or less homogeneous, while the least eco-conscious sub-group was significantly different from the former 2 sub-groups in terms of eco-consciousness. As the wetland users were found to be diversified in terms of their eco-consciousness, it is necessary to plan the wetland management policies in consideration of such differences. However, it is perceived that the wetland amenities need to be built to meet the more eco-conscious users.

최근들어 세계환경의 화두는 습지와 더불어 논습지 그리고 습지의 생태계서비스 기능에 집중 조명되고 있지만, 논습지의 생태계서비스를 평가 할 수 있는 연구체계가 부족한 실정이다. 따라서 본 연구는 기존의 습지평가체계를 논습지에 적용하여 습지로서 논의 가치를 평가해보는 동시에 논습지 중심의 평가체계를 구축하는 기초자료로 활용하고자 연구를 진행하였다. 연구 대상지는 고도와 토양을 기준으로 16곳을 선정하였다. 습지평가 결과 연구대상지 16곳은 총점 110점~118점, 평균 2.17~2.50으로 선행연구 사례지인 호수형습지, 소택형습지, 하천형습지와 비교해도 습지로서 가치가 인정되었다고 할 수 있다. 하지만 고도, 토성에 따라서는 평가결과의 차이는 없었으며, 보전가치는 모두 같게 나타났다. Pearson 상관분석을 통해 보전가치에 가장 밀접하게 작용하는 요인을 찾아본 결과, 면적이 상관관계가 있는 것으로 나타났다. 그러나 기존의 습지평가체계로 논습지에 적용하기에는 한계가 있는 것으로 사료되어 논습지 평가를 위해서는 재배유형, 지형적 특성, 식생특성, 생육환경, 생물다양성 등의 다양한 후속 연구를 통해 습지평가체계를 보완할 필요가 있는 것으로 판단하였다.

전라남도 신안군 흑산면 대장도에 부존하는 장도습지는 선캠브리아기로 추정되는 매우 심하게 규화된 변성퇴적암층을 관입한 화강암이 풍화되어 형성된 와지로 사료되며, 습지주변으로 비교적 다양한 화강암 풍화지형들이 관찰된다. 그리고, 장도습지의 형성은 화강암이 차별침식작용에 의하여 잘게 부스러지고 암편들이 홍수성 강우나 혹은 표토의 사면이동으로 낮은 경사지형이 되었고, 그 결과로 습지가 형성될 수 있는 지형특성을 보인 것으로 잠정적으로 해석된다. 또한, 습지주변의 사면토양과 습지퇴적물을 분석해 본 결과, 장도습지는 주변 사면토양의 영향하에 있는 환경이라고 할 수 있다. 이러한 환경에서 습지로의 수분공급은 오랜 기간동안 지속되어 지형적으로 오목한 곳에 수분과 유기물을 끊임없이 공급하여 유기물의 분해가 잘 이루어지지 않는 습지환경을 만들어 냈으며, 습지에 적합한 식생들이 정착하여 지속적으로 습지의 두께를 높여 현재의 습지를 형성해 낸 것으로 사료된다.
