The present Namgang Dam had been completed in 2000, Salix subfragilis communities began to form in 2003 and their distribution area have been rapidly extended into nine times in 2010. In order to deduce correlation between water level and distribution of Salix subfragilis communities under this background in Namgang-dam reservoir, distribution characteristics and widening direction of Salix subfragilis communities have been analyzed by aerial photographs and water levels has been reviewed, also heights and ages of Salix subfragilis have been surveyed in field. The water levels of Namgang-dam related germination of Salix subfragilis have been analyzed in May and June from 2000 to 2010, mean water level, minimum water level and maximum water level were 37.87m, 36.99m and 38.82m, respectively. The oldest ages were 9-13 years, average diameters of breast height, average heights, average numbers and average crown area were respectively 3.9-8.8cm, 3.8-7.5m,
in sites. Therefore, this results showed that the first recruitment of Salix subfragilis was in May 2002 when water levels have been maintained as 38.76-41.31m and the widening of Salix subfragilis communities was in May 2004 and 2005 when mean minimum water levels have been maintained as 38.76-41.31m. Salix subfragilis communities formed climax forest in Namgang-dam shore, this phenomena were different from the succession processes of Salix in rivers appeared landforming by deposition of sediment.

Recently, the importance of forest landscape as a visual resource has been increased, so it is emphasized that the necessity of forest landscape management through `Forest landscape management master plan` and `National Forest landscape belt`. As such, this study aims to suggest a method for forest landscape management plan considering visual landscape analysis and regional landscape resources in case of Sangju-si, Gyeongsangbuk-do. Accordingly, this study has investigated regional landscape resources and surveyed existing forest conditions of target area. In order to analyze the characteristics of visual landscape, landscape control points are selected through viewshed analysis. And, Forest landscape plan is suggested 3 areas considering comprehensive analysis of forest landscape resources survey and characteristics of visual landscape:the landscape resource management area, the landscape resource restoration area and the landscape resources exploit area.

South Korea had encouraged farmers to breed bear to increase farmer`s income since 1981. Currently farmers breed over thousand number of bears, however but the policy measures for breeding bears is expected to conflict the main stream of bear conservation due to South Korea belong to the member of CITES, which categorizes and manages bears under Wild Fauna and Flora Protection Act. Government needs to establish a special law containg the win-win relief strategy not only for farmers of breeding bears, but international corresponding policy. So, we have reviewed the domestic status and international trends on breeding bears, and suggest the alternative strategies of the policy such as a bear park, a bear village, use of species recovery center, use of a preservation organization. This policy should be accompanied with more detailed fact analysis, management agency, well equipped welfare facility and financial preparation for proper management of breeding bears against changing international trends on wildlife conservation.

As ten years have passed since national parks were adjusted and released inceptively, it is the time for evaluating the effectiveness of the national park policy and improving it on the basis of the evaluation result. In this study, the method of appraising the environmental and socio-economical ripple effect on the implementation of national park regulation were provided, based on the institutional consideration, the environment analysis, the survey of residents consciousness, the statistical analysis and so on. It is applied to target sites where were released from national parks, and the policy direction was suggested for sustainable use and management of national parks. National parks, that exhibit various characteristics depending on geographical and local conditions, were categorized through the statistical approach. Released sites from Seoraksan National park, where was categorized as the core national park for sustainable use and management, were evaluated environmentally based on the time-series analysis of environmental thematic maps and socio-economically based on the survey on residents perceptions. As a result of this study, the environmental effect of released sites has been declined or threatened, and the residents` economic, social and living condition in these areas are still not improved(p<0.05) since the adjustment of national parks. Based on the policy approach reflecting regional characteristics, natural resources are kept and enhanced for the sustainable use and management of national parks. And a consensus on the national park policy of national park should be developed between local residents and voluntary participation and public awareness should be attracted from them, based on the construction and the supplement of the infrastructure.

The purpose of the study is investigating the price fluctuation of landscaping plants in the Information on Commodity Prices(ICP) and the posted price fluctuation of landscaping plants of Public Procurement Service(PPS) recent 10 years. It also provides the basic information which can be applied to production and sales of landscaping plants, comparing with general price index. The major findings of the study are as follows. First, The price of investigated plants of PPS has increased about 4.56% in average recent 10 years. Among this increase, of evergreen tree was predominant. On the other hand, landscaping trees price of ICP has increased about only 2.34% in average. Secondly, The result shows that average price of investigated plants of PPS is positively related with the price of ICP. For this reason, we found that prices of ICP and of PPS move together in most case. However, we found that there are no relation between Consumer Price Index(CPI), Producer Price Index(PPI) and Agricultural Price Index(API). Therefore, price fluctuation of landscaping trees moves regardless of normal price fluctuation in general. Third, even though result shows that price index of evergreen trees, deciduous trees and shrubs are weakly related with normal price index partly, it was not high enough to be significant. According to the result, we found that price of landscaping plants is not related with market situation. For this reason, we thought that there are some difficulties for the reasonable production and sales of landscaping plants because the price is somewhat decided by rule of thumb. Therefore, understanding the composition of cost and making prediction by price fluctuation available are needed so that it can be practically conducive to reasonable production and sales.

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.
A Case Report on the Constructed Wetland for the Growth of Sphagnum palustre

Construction of an artificial wetland for the growth of Sphagnum palustre with emergent macrophytes (Phragmites australis, Typha angustifolia, and Zizania latifolia) was firstly tried and the growth of those plant components according to various environmental combinations has been monitored for three years. Above-ground dry weight of Z. latifolia (
) was higher than T. angustifolia (
) and P. australis (
) under most environmental conditions. In overall, planted emergent macrophytes seemed to prefer polishing sand without moss peat as a substrate and relatively deep water-depth condition (20cm) rather than shallow water-depth (5cm). Despite of high calcium content in inflow water (> 15ppm) into the constructed wetland, S. palustre populations have survived in most experimental plots during the monitoring period. Substrate layer including moss peat with high surface-area might play a role as an ion-filter. After three years, relatively thicker litter-layer in Z. latifolia plots due to vigorous growth appeared to heavily depress S. palustre by physical compressing and complete shading processes. Most of all, for the continuous growth of S. palustre, physio-chemical characteristics of water and substrate must be carefully managed. In addition, companion emergent species should be also cautiously selected not to depress S. palustre by much litter production. We suggest P. australis and T. angustifolia as companion species rather than Z. latifolia.

This study was carried out to investigate the changes of plant species and soil physicochemical properties on green roofs established at Seoul Women`s University in 2005, 2006 and 2007. The plant species and soil properties were investigated in 2013. The areas of green roof sites ranged
. There were floras of vascular plants of 12 families, 20 genera and 22 species in the 2005 site, 24 families, 37 genera and 38 species in the 2006 site, 14 families, 27 genera and 31 species in the 2007 site. The total number of plant species decreased in the 2005 and 2006 sites and increased in the 2007 site since established. High proportion of dispersal type was barochory in the 2005 and 2006 site, and autochory in the 2007 site. And the proportion of the compositae family was high in the introduced plants over the sites for the all study sites. Average pH and organic matter concentration of green roof soil were ranged from 5.25 to 5.96 and 7.17 to 8.96% in study sites. The organic matter concentration and pH of green roof soil were lower in 2013 than in the three establishment years. Carbon concentration of green roof soil in the three study sites were ranged from 4.16 to 5.30% and total soil carbon in 10cm depth were ranged form 1.57 to

The purpose of this study is to develop riverbed techniques to activating ecological function of hyporheic zone. Hyporheic zone maybe simply defined as an active eco-tone between surface water and groundwater, which facilitates to exchange water, nutrients and aquatic habitat occur in response to variation in discharge and bed geomorphology. The aim of this study is to evaluate the effectiveness of an applied riverbed technique for two years since its installation in the hyporheic zone. The experimental riverbed technique has been implemented on Anyang stream penetrating Anyang city in Gyunggi province. The dimension of the installed structure is 5.0 m in width, 46 m in length. Bottom layer is filled with rip-rap covered with gabion. After the implementation of the technique, the study conducts follow-up monitoring in two years of between 2011 and 2012. The results of follow-up monitoring for two years are as follows:1) In Hydro geomorphic process, the riverbed technique maintains hydraulic stability despite of several flood events in 2011, 2012. 2) After transformation to form pool-and-riffle habitat, for aquatic community composed of freshwater fish, macro invertebrate, and attached algae, the species diversity and population gradually increased. 3) The riverbed technique achieved desired effect on enhancement of ecological function in hyporheic zone.

DOI : 10.13087/kosert.2013.16.6.135
Ultrasonic mist fogger and the fan were used for investigating the availability of fog circulation system in greenwall and the potential growing ability of the plant. The mist caused by ultrasonic mist fogger was circulated by the fan through the pipeline and supplied to the pots containing plants. Moisture content of the 3 different soils was measured at different irrigation time points. The moisture content of 15-26% in PP and Co soil was maintained at irrigation of 24H, 18H, 12H in a day. Proper growth condition was found in Ardisia pusilla and Hosta plantaginea at the height of L level after 1 month of growth when the plants were irrigated by the fog circulation system. The results suggest that the fog circulation, by ultrasonic mist fogger to the green walls is system of choice for suppling moisture to plants.
