This study was carried out to suggest the baseline data necessary for vegetation restoration at riverine wetland within stream corridor. We used the prevalence index for wetland assessment by applying the method of weighted averages with index values based on five hydrophyte indicator status as defined by estimated probability occurred in wetland. We selected near nature and urbanized reach of Gap and Yanghwa streams as experimental site. Although two sites have some different disturbance and characteristics of watershed, they showed that similarity of vegetation community including three dominant species - Salix koreensis, Phragmites communis, Miscanthus sacchariflorus - was very high. But in case of Yanghwa stream, various kinds of emergent plants along wetted condition were distinctly occurred, resulted from difference of hydrological regime and substrate, etc. Degree of naturalness of vegetation at the sampled areas indicated that near nature area of Gap stream and all area of Yanghwa stream were fitted as riverine wetland, while urbanized area of Gap stream has changed into upland condition. In conclusion assessment system using prevalence index would be considered an effective method for evaluating of natural states of riverine wetland, but further integrated consideration of physical, hydrological, and biological factors of stream process, and also with considering the difference between those qualitative data of vegetation community.

This study is to investigate the conditions closely related to the establishment of vegetation in the riparian zone: the soil condition, an important factor along with climate and light. Especially, the soil structure of the microtopographical formations in the specific area known as the riparian microtopographical zone investigated. In addition, the effect of the riparian microtopographical features on the ground water level, soil moisture content, and vegetation was studied. The results of this study are as follows; 1) At all sample sites, below the sand layer, a gravel layer is always present. This is the result of past floods. 2) Although Salix koreensis experiences frequent disturbances such as increase in river level and floods, this vegetation establishes itself in the most secure are in the microtopographical zone. 3) The growth of Phragmites japonica is closely related to the underground water level. 4) It is clear that Miscanthus sacchariflorus grows concentrated in dry areas. 5) The soil accumulation conditions differ according to the soil moisture content of each microtopgraphical feature. Accordingly, the moisture content of the soil is clearly different within the microtopographical zone. The continuous and long-term investigation and research on the relation of riparian reproduction and the relevance with location surrounding factors are necessary in the future.

The De-militarized Zone(DMZ) on the Korean Peninsula is ecologically conserved and naturally developed as access to the area has been controlled in the past five decades. As a result, biodiversity and wetlands are developed very well, but they have not been sufficiently surveyed due to land mines and security reasons. Focusing on the Kyongui Line area in Paju DMZ, this study aims at examining the status of forested wetlands in detail through an on-site survey and understanding the features of forested wetlands in DMZ. The forested wetlands of Paju Kyongui Line area are inhabited by naturally grown Salix koreensis Andress. and Acer ginnale Maxim. and affected by Sacheon Basin region extensively. As the topography of this region is created of inundated area and gentle ground, it is easily affected by hydrology and irrigation and has ideal conditions as forested wetlands. In addition, forest wetlands in this area were used as agricultural land in the past but now transformed into palustrine forested wetlands after being deserted for long time. However, as construction of roads and railways increasingly blocks water paths, the coverage of Robinia pseudoacacia L. and Amorpha fruticosa L. is on the rise, which indicates that forestedwetlands are gradually becoming inland over time.

댐 건설이 주변 환경에 미치는 영향에 대해서는 주로 기후와 농산물에 초점이 맞추어져 연구되어왔다. 본 연구는 댐 건설에 따른 주변 식생의 변화를 알아보기 위하여 조사 장소를 준공 후 33년이 지났으며, 저수용량이 우리나라에서 가장 큰 소양강댐으로 선택하였다. 소양호의 범람지, 범람지보다 고도가 5m 높은 범람지 위쪽, 그리고 호수로부터 능선을 사이에 두고 3km이상 떨어져 있는 대조구에서 방형구법을 통한 식생과 토양함수량 조사가 이루어졌다. 관목층~교목층의 평균상대우점치는 범람지는 버드나무(87.9%)가, 범람지 위쪽과 대조구는 신갈나무(38.9%, 40.4%)가 가장 높았으며, 초본층의 상대우점치는 범람지에서는 사철쑥(34.2%)이, 범람지 위쪽과 대조구에서는 주름조개풀(19.4%, 24.6%)이 가장 높았다. Shannon-Wiener 종다양도 지수는 관목층~교목층에서 범람지(0.26)가 범람지 위쪽(2.34)과 대조구(2.23)보다 낮았으며(p<.01), 초본층에서는 3 모둠간에 유의한 차이가 없었다. S${\o}$rensen의 군집유사도 지수는 범람지와 범람지 위쪽, 범람지와 대조구에서 낮았으며, 범람지 위쪽과 대조구는 비교적 높았다. 교목과 아교목의 흉고직경별 개체수는 범람지에서 5~10cm인 버드나무(240/ha)가, 범람지 위쪽과 대조구는 모두 15~20cm인 참나무속 식물(400/ha, 466/ha)이 가장 높은 밀도를 보였다. 치수는 범람지에서 소나무(7,040/ha)가, 범람지 위쪽과 대조구는 모두 참나무속 식물(720/ha, 400/ha)이 가장 높은 밀도로 출현하였다. 토양함수량은 범람지(6.28%)가 범람지 위쪽(11.13%)과 대조구(10.14%)에 비하여 낮았다(p<.01). 조사 결과, 소양강 댐 건설로 인해 범람지는 식생이 변하였지만, 그 바로 위쪽에서는 식생의 변화가 나타나지 않았다.
