Journal of the Korea Society of Environmental Restoration Technology, volume 11, issue 5, 2008, Pages 1~11
This study was carried out to provide primary data set for cleaning of contamination site. By having hydroponic culture on Salix alba and S. caprea seedling treated with Ni solution, the result of Ni accumulation came out as followings : In a treatment of Ni to the Salix alba and S. caprea, Ni accumulation increased in its root, leaves, and stem, as Ni concentration became higher until
. But in a
treatment, the seedlings died after 4 weeks. Ni accumulation in the Salix alba and S. caprea was the highest in its roots, second-highest in leaves, and the lowest in stems. In the case of
treatment of Ni solution, Ni accumulation in roots were above 500.0mg/L, and leaves were above 20.0mg/L. But it was lower than 13.0mg/L in stems. Ni accumulation in the plant increased more when nutrient solution containing Ni was weekly changed than just refilling the same amount of nutrient solution that evaporated Ni accumulation in Salix alba was higher than S. caprea when the nutrient solution had been refilled only.

With recent emphasis on the creation of environment-friendly new towns, introduction of ecological facilities for habitation and migration of wild animal's species is requested when developing new towns. In order to introduce such facilities, building an eco-network within the site based on the connectivity of the source area and habitats is essential in new town development. Therefore, this study mainly aimed at selecting species targeted for building an eco-network in Pangyo new town, which is intended to be an environment-friendly city. Therefore, criteria for selecting target species were generated. Then, species observed within the site through field surveys and literature review was evaluated based on the selection criteria and items. By totaling the score, a list of appropriate targeted species was finalized. Among species surveyed and observed in the site, appropriate target species that may be selected for Pangyo new town's eco-network include Falco tinnunculus interstinctus, Accipiter soloensis, Picus canus, Paradoxornis webbiana, Parus palustris, Parus ater, Parus major and Passer montanus Egretta in birds, Asiatic chipmunk, Nyctereutes procyonoides in mammals. For Pangyo new town, it is essential to create living environment and build a network for major wild animal species within the site based on target species. This will play a crucial role in building a reasonable ecological network enabling harmonious co-existence between mankind and nature. In order to build an ecological network successfully, follow-up studies need to be conducted on restoration technology and methods required for creating habitats appropriate to target species.

A field survey was performed at the Human-made Wetlands along Boknaecheon of Juam Lake from March 2004 to October 2007 for the purpose of investigating changes of flora for 4 years since its creation. A total of 15 species including 10 families, 13 genera, 12 species and 3 varieties were planted at the Human-made Wetlands along Boknaecheon of Juam Lake which was completed in December 2002. The survey conducted in 2004, 15 months after creation of the Human-made Wetlands, revealed a flora composed of 47 families, 102 genera, 112 species and 19 varieties, 131 taxa in total. In 2007, further increase was registered with 46 species added compared to 2004 reaching 177 species in total. A 4-year monitoring of naturalized plants showed that no quick but constant increase was featured yearly in their number of species with 12 in 2004, 17 in 2005, 18 in 2006 and 19 in 2007. As for changes in life form, 13 species of perennial plants and 2 woody species, 15 in total, were planted initially but, in the survey 2004, 1- or 2-year old therophytes numbered 73, perennial plants 54 and woody species 4, indicating a large change of life form accompanied with increase in overall number of species. The number of 1- or 2-year old therophytes and perennial plants featured a steady increase each year from 2005 to 2007. The distribution ratio of 1- or 2-year old therophytes, however, showed a gradually decreasing tendency while perennial plants tended to increase, instead. As evidenced in changes of flora at the Human-made Wetlands, most of species in it have been determined to be fit or not within 1 to 2 years after its creation and, since the stable settlement of these species onward, its life forms have undergone stepwise changes together with the number of species and individuals in parallel with repeated extinction and penetration of plants.

This research has a meaning to provide basic data for eco-friendly way of district unit plans and ecological landscape planning by evaluation of biotope preservation value at the level of district unit and designating land development of the site, the whole area of Sinseo-dong (Dong-gu, Daegu metropolitan city) for research site. The summary of analysis result is as follows. As a result of classification of biotope types on the research site, it is divided into 11 biotope groups such as a residential biotope group and 51 specific biotope types which is subordinate to the groups. As a result of the first value assessment on classified biotope types, there are 16 types of natural rivers which is full of vegetation as a I class. Also it is analysed as 9 types of IIclass, 14 of IIIclass, 8 of IVclass, and 4 of Vclass. In particular, in light of a wildlife habitat, EB, in case of broad-leaved tree of mixed forest assessed as a II class, was classified into Iclass which is one-step upgraded as a final class with the analysis as there is a structural characteristic (more than 71% of low density, 50 years of age-class). As a result of second assessment, it is analysed that there are 17 special sites (1a,1b) and 33 special sites (2a, 2b, 2c) respectively for preservation of species and biotope. Particularly, in case of the No. 27 space, it was assessed that it has the value of about medium (IIIclass) level, but its value was upgraded with the on-spot detailed investigation that most of Aristolochia contorta, designated as a rare plant by Ministry of Environment, is growing. It is regarded that the above-mentioned research result on evaluation of biotope preservation value is expected to provide very important basic materials for future district unit plans and smooth integration with landscape ecology plans and eco-friendly space development.

Through analyzing the specific physicochemical alterations in depth-based soil at reclaimed dredging area, the baseline data were provided for developing the reclaimed dredging area as natural landscape planting sites and ecological-landscape sites based on the soil improvement technology. There was no physical disturbance for 15 to 20 years in Gwangyang Bay reclaimed dredging area after reclamation. Physicochemical examinations of the soil were performed based on the vertical depth. Results of physicochemical analysis such as pH, electric conductivity, total salt contents, silt, clay contents, available phosphorus, calcium, magnesium, sodium, chlorine, and sodium-adsorption ratio showed increasing patterns with the depth while total organic contents, total nitrogen, and sand showed decreasing patterns. Potassium as an exchangeable cation, showed similar distribution patterns between the shallow and deep soil. This result strongly implied that long-term exposure to natural rainfall in reclaimed dredging area altered soil characteristics related to salinity. This research demonstrated that there were no remarkable differences in physicochemical characteristics at soil depth and groundwater table height, suggesting a baseline data for developing reclaimed dredging area. Additional investigation is required for different reclaimed dredging areas. Also, additional monitoring and examination are need on plant communities and time variable alteration in the soil to test the feasibility of reclaimed dredging areas as natural landscape planting sites and ecological-landscape sites.

Research was initiated to investigate germination characteristics of creeping bentgrass (CB, Agrostis palustris Huds.). Seven varieties of CB were evaluated with different experiments. An alternative environment condition requiring for a CB germination test by International Seed Testing Association (ISTA) was applied in the Experiment I, consisting of 8-hr light at
and 16-hr dark at
(ISTA conditions). Experiment II was conducted under a room temperature condition of 5 to
(natural conditions). In each experiment, data such as seed germinating vigor, early germination characteristics, germination speed and germination peak time were measured. Significant differences were observed in seed germinating vigor, early germination characteristics, germination speed and germination peak time. Seed germinating vigor was variable with different environments and varieties. It was 61.50 to 98.25% under ISTA conditions and 55.00 to 98.50% under natural conditions. There were considerable variations in early germination characteristics among CB varieties according to different conditions. Early germination characteristics indicated that all varieties were 1 to 4 days faster in germination under ISTA conditions, when compared with natural conditions. The germination speed, measured as days to seed germination of 70% and 90%, was much faster with Penn A-1, Penn A-4 and Penncross under ISTA conditions. But it was even faster with L-93 and Penncross when grown under natural conditions. Differences were also observed in germination peak time with varieties and growing conditions. It was 0.57 to 2.86 days under ISTA conditions and 0.74 to 1.74 days under natural conditions. Regardless of the environment conditions, the shortest variety was L-93 and the longest one T-1. Considering germinating vigor, early germination characteristics, germination speed and germination peak time, Penn A-1, Penn A-4 and Penncross were regarded as excellent varieties under ISTA conditions in terms of early establishment characteristics, while L-93, Penn A-1 and Penncross under natural conditions. These results suggest that an intensive germination test be needed prior to planting, for the early germinating vigor, germination speed and germination peak time. Also, a proper variety selection and comprehensive site analysis for the growing environmental conditions should be done before golf course construction.

Development of new approaches to achieve naturally good ecological potential of forest road cut-slope by making the best use of advantages of gabion systems with vegetation base materials to prevent slope failure and erosion, in the area with highly erodible soil. As a result on the type analysis of gabion systems already installed in road cut-slopes, gabion systems were generally established to prevent slope failure. Existing gabion systems can be divided into monolithic and modular system and can be divided into ten subtypes according to the purpose of establishment and combination of other measures. As a result on the monitoring of erosion amount from forest road cut-slopes in the test applications, the order of erosion amount from largest to smallest is as follows : the curved road cut-slope site where normal gabion system was established (
); the control site (
); the straight road cut-slope site where normal gabion system was established (
); the curved road cut-slope site where the new gabion system was established (
); and the straight road cut-slope site where the new gabion system (
). Therefore, the result shows that the new gabion system is more effective than the normal gabion system to reduce erosion amount from forest ! road cut-slopes. During the study period, vegetation coverages of the straight and curved road cut-slope site where the new gabion system was established were about 45% and about 36%, so average vegetation coverage of the sites where the new gabion systems was established was higher than the sites where the normal gabion systems was established. Therefore, it was concluded that the new gabion system can be more effective for cut-slope revegetation.

The importance of the green space in urban area has been increasing. There are the increasing needs of creation and sustainable management of urban forest. In order to satisfy the need, it is necessary to set indicators for sustainable urban forest. With this regard, this study is to derive the indicators for evaluation of the urban forest through literature reviews, experts opinion, and field survey. The results of the study, the indicators consist of the ecological healthiness, socio-cultural function, and scenic beauty. The ecological healthiness includes stability and naturality (e.g. area, native species, connectivity etc.). The socio-cultural function contain improvement of living environment, stable emotion, community, and environmental education. The scenic beauty includes environmental-friendly facilities, maintenance of urban forest. The indicators have high feasibility to create and manage the urban forest through evaluating urban forest in practical. This indicators are useful to guide to develop urban forest and park.
