Development of housing, industrial and public lands has been a cause to increase a temperature of a city higher than that of a rural area. Knowing that, the research analyzed temperature changes in a riverside district and a coastal area depending on the land usage and climate change in the areas. Add to this, the study examined a correlation between topographic characteristics and temperature changes. According to the results, the temperature was increased by $1.80^{\circ}C$ in 2007 comparing to 2003 while the wind velocity was reduced by 0.24m/s. In addition, a more number of areas were designated as build-up areas which, in return, decreased the forested land. The analysis on the correlation reported that the riverside district has more of grassland and bare land while the coastal area has more of wooded land and grassland. The study is expected to be used as fundamental data for research on heat island effect which would be different by each regional characteristic as it proposes measures to solve the heat island effect.

Polygonatum stenophyllum Maxim. is a native perennial herb to Korea belonging to family Liliaceae. Although it was removed from the endangered species list, since it inhabits the riverside, it has been threatened with damage to its populations due to frequent disturbances. In order to reveal the basic ecological characteristics of P. stenophyllum, This study was identified the life cycle of the aboveground part and was measured the number of flowers and fruits, which are reproductive organs of P. stenophyllum in riverside in Paju - si during the two years. As a result, aboveground part of P. stenophyllum appeared and grew rapidly until the end of May to about 1m. In early May, two buds per one peduncle were formed up to six pairs per floor. The flowers bloomed in turn from the base of the stem and to the top floor and the blooming occurred when the number of leaves was at least three. Fruits were formed in mid-June and matured by the end of September. The numbers of flowers and fruits were revealed that flowers bloomed in turn from the bottom of the stem to the top floor, the most intensively bloomed in the center part of the stem, and did not bloom from the floor closest to the ground and above the highest 5th node. This basic ecological characteristics of the P. stenophllyum grown in riverside identified in this study will be useful as basic data for their conservation.

In case of the axial line bikeway, the residents in the riverside use it frequently but those in the city center hardly do as the axis is formed along the riverside of the Han river. This situation happens due to the inefficient connectivity between the bikeway that leads to the riverside and that in the city center, which means the administrative policies have been focused on the facilities rather than on raising connectivity of the bikeway networks in the south of the Han River. Also, this is the point of time when a reasonable improvement plan is needed to raise the accessibilities of the bikeways in Seoul, not just a utilization of those in the south of the Han River. This study intends to analyse the connectivity between Gangseo (west of the Han River) and Gangdong (East of the Han River) districts by comparing the current spatial structure in the southern areas of the Han River and that after the installation of the axial line, and that after installation of the ordinary bikeway respectively with use of the Space Syntax Model, and to predict resultant changes there of. The Space Syntax Model was used as the major method of analysis in this study to find out characteristics of the bikeways in the south of the Han River. Consequently, as the analysis shows that when the bikeways in the Gangseo and Gangdong-gu districts are connected, the accessibility of the bikeways in the south of the Han River will improve while the spatial structure intelligibility will be lowered, it can be said the prediction rate in the all areas is low compared with the current status. It is analyzed that the intelligibility of the current bikeways in the south of the Han River appeared highest when compared with those of plans for installation of the axial line and ordinary bikeway because they don't interconnect with other areas.

The purpose of this study is to offer raw data on managing naturalized plants and the ecological characteristics of urban streams by researching the naturalized plants distributed in Naedong Stream, Changwon-si. The results are as follows. The numbers of naturalized plants were summarized as 45 taxa: 18 families, 38 genera, 43 species and 2 varieties. There were 3 taxa of invasive alien plants: Rumex acetocella, Ambrosia artemisiifolia var. elatior and Sicyos angulaus. In an analysis of life forms, there were 2 taxa of megaphanerophytes, 1 taxa of nanophanerophytes, 3 taxa of chamaiphytes, 7 taxa of hemicryptophytes, 1 taxa of geophytes and 31 taxa of therophytes. The urbanized and naturalized indices were 16.6% and 25.1%, respectively. The results of an analysis by vertical structures showed that naturalized plants included 30 taxa upstream, 42 taxa midstream and 32 taxa downstream. For the urbanized index, upstream was 11.1%, 15.5% in midstream and 11.8% in downstream. For the naturalized index, upstream was 21.7%, 33.3% in midstream and 37.2% in downstream. An analysis of crossing structures showed at taxa of 39 naturalized plants on bank. 30 taxa along the riverside and 7 in the water. For the urbanized index, banks were 14.4%, riverside 11.1% and waterside 2.6% while the naturalized index included 30.5% on the banks, 30.6% along the riverside and 20.0% in the water. As regards the management of naturalized plants, because Remex acetocella, Ambrosia artemisiifolia var. elatior and Sicyos angulaus have a negative impact on the ecosystem, they need to be efficiently controlled.

This study was conducted to determine the content of trace metals in crops cultivated in Han-riverside, Anyang stream, Tan stream, and Jungryang stream. Trace metals (Pb, Cr, Cd, Fe, Zn, Cu, Hg) were detected in 36 crops, 285 samples by Atomic Absorption Spectrophotometer and Mercury Analyzer. The average concentration of trace metals in crop samples was in the order of Fe (34.592 ppm)>Mn (11.071 ppm)$\geq$Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm). In crop samples, the contents of Fe, Cu, Mn, and Zn, which ranges were 0.004-203.083 ppm, 0.017~22.727 ppm, 0.000~74.373 ppm, 0.080~37.166 ppm, respectively, were relatively higher than those of Pb, Cd, Cr, and Hg, which ranges were 0.000~0.654 ppm, 0.000~0.270 ppm, 0.000~l.229 ppm, 0.000~0.037 ppm, respectively. The concentration of trace metals in crop samples was in the order of leafy vegetables > stem vegetables > root vegetables > fruity vegetables. In the root vegetables, such as radish, the content of Pb was leaf(0.055 ppm)>root(0.035 ppm), that of Cr, leaf (0.118 ppm)>root(0.031 ppm), that of Cd, leaf(0.004 ppm)>root(0.001 ppm), that of Hg, leaf(0.004 ppm)>root(0.001 ppm). As the results, it could be thought that root is the organ which doesn't accumulate the heavy metal ions, but absorb them.

In this study, changes in the fluvial landforms of the Yeoju section of the Han River, which was made up of the Han River Restoration Project, were examined through existing previous research data, government's environmental impact assessment data, satellite images, and field observations. For example, In the vicinity of Dori Island, the most upstream part of the study section, the location of the confluence of the Han River and Cheongmi Stream was changed, and it was found that a significant portion of the sand sedimentary layer disappeared. In the Bawuinupgubi area, the wetland, which is the first class in the ecological nature, was greatly modified, and the elevation of the ground rose as Gangcheon island and it was completely separated from the river by dredging The confluence of Geumdangcheon and the point bar of Yeonyang-ri in the south were also dredged, turned into an artificial waterfront park, and a chute channel remained in the form of a wetland was also developed as a recreational park. The deposional forms around Baekseok-ri islands also disappeared as dredging was carried out. Among the areas adjacent to the confluence of Bokcheon and Yangchon-ri Island, some sedimentay forms remains, but the abandonned channel between Yangchon-ri and the northern river bank has been changed into a riverside reservoir through dredging and embankment construction, and the waterway of the tributary river(Yazoo) has been greatly changed.
