We examined three nature restoration projects in urban areas of Japan, China, and Korea. A prefectural park(29ha) has been under construction since 2005 on an abandoned industrial site in the southern part of Amagasaki City, Hyogo Prefecture, central Japan. Shanghai Central Park(28ha) was redeveloped in 2002 on a site that was formerly the old downtown in central Shanghai. Seoul Forest Park was developed as a large urban park(116ba) in 2005 in Seoul. All three parks were developed as urban parks by local governments. Citizen involvement is common to all three examples. One of main purposes of the Hyogo prefectural park and the Seoul Forest Park was the reuse of unused or abandoned areas. One goal in Hyogo, Shanghai, and Seoul was to restore the urban ecosystem and preserve the environment. We discussed the meaning of nature restoration in urban areas.

About 50% of the population and 75% of the properties concentrate on the flood plain in Japan. The rivers have intimate relationship with our lives. Those conditions have been seen after modern river improvement projects that began about a century ago. The technology which was introduced from foreign countries was improved in conformity with geographical features and the climate condition of our nation, and has redeveloped as a Japanese original technology. In 1940's, Japan had serious natural disasters that were caused by large- scale typhoons. Those typhoons wiped out everything completely. Even though the government realized the importance of flood control and management after those natural disasters, civil work still aimed to economic development. Those construction works have become the one of factors for concentrating population and degrading natural environment in urban areas. Deterioration of river environment has become serious issue in urban development and main cause of pollution. The approaches for environmental restorations which were started about 30 years ago aimed to harmonize with nature environment and cities and human lives. There have been going on many projects called 'river environmental improvement projects', the 'nature friendly river works' and 'natural restoration projects.' The society has tried to find a way to live in harmony with nature. As for societies symbiotic with habitats will form the safe country in the history and the spectacle. Such as the symbiotic of the river or the basin where discharge, water quality, nature, the history, landscape, the local society and also for culture were built in is achieved. Examples of working, applied to restoration technologies and the one to describe the mechanism construction are been shown in the paper. Furthermore, write for an international spread of the river technology of Japan to attempt.

Today most landscape architects and scientists have approached ecological restoration, only in a scientific way or on aesthetic way so as to deal with the complex phenomena of a site easily. However, 'the real world' as well as 'ecological nature' as it is can not be totally dealt by the scientific approach which is quantitative and reductioinal. ince a site to be restored has the character of 'place' where man 'dwells', it must be designed and built as total phenomenon. In terms of Martin Heidegger's interpretation of "revealing", we might find out how to overcome the dilemma of the 'modern technology'. To the point of the phenomenological integrity between 'modern technology' and 'art', we can reveal 'sense of place' on a site. The phenomenological approach, which is related to the characteristics of the site, implies something more than scientific since it focuses on the development of site-specific data without wasting extra data for ecological restoration. Bodily experiencing a site with the perception, man discloses the site's nature and he also analyzes it in a scientific way. Therefore the phenomenological approach might be a clue of constructing ecological restoration as well as construing the identity of landscape architecture.

Ecological restoration is an ecological technology that diagnoses problematic ecological spaces and restores the damaged ecosystem to a healthy appearance similar to its original appearance based on reference information obtained by analyzing intact nature. To achieve successful restoration, the project must be carried out in respect of a series of procedures. However, in Korea, restoration projects are usually actively promoted regardless of diagnostic evaluation, which wastes cost and energy, and the effect is not significant. As the reference information is not utilized, ecological restoration to return the damaged nature makes features different greatly from the appearance of nature, causing another damage. As the restoration effect is not evaluated, it is impossible to determine whether it is successful or not, and as a result, even if the project continues, there is no development and no effect. However, advanced societies have not only made academic progress by respecting these procedures but also have great economic effects along with the improvement of environmental conditions as ecological restoration has become an industry. Therefore, the international society recognizes ecological restoration as an important means of solving environmental problems at the global level, including climate change, and international organizations are actively promoting projects to treat the injured planet. However, most of the restoration projects promoted in Korea were evaluated below the level as a result of the evaluation of the effect. Nevertheless, those who have led low-quality projects are blocking plans to establish ecological restoration as a new industry that can contribute significantly to improving these levels, and thus the problem is expected to worsen. To solve this problem, it is necessary to filter out defective businesses by introducing a strict and correct project evaluation system by dividing it into before and after. Furthermore, it is necessary to establish ecological restoration as an industry and leave the process in the principles of the market.

The purpose of this study was a biota research and analysis for Close-to-nature stream restoration planning of Shinchun. The summary of this study is as follows; 1) The vascular plants in research area recorded of 45 species and insect fauna recorded of 34 species of 8 orders. As a result of table of community classification, the communities were two group; Quercus variabilis community(I), Pinus densiflora-Quercus variabilis-Quercus dentata community(II). 2) As a result of analysis on correlation of tree species, the level of significance in positive correlation between Quercus dentata and Corylus heterophyll aindicated 1% and between Pinus densiflora and Lespedeza bicolor also indicated 1%. 3) As a result of DBH analysis, it is expected that Quercus variabilis and Quercus dentata will dominateover other species in competition and its succession continuously maintains from now on in community I. In community II, it is assumed that there is a high possibility of changing into community of Quercus such as Quercus mongolica, Quercus dentata, and Quercus variabilis. 4) As a result of analysis on insect fauna, insect fauna consists of 94% of whole species as 32 species, 23 families, 8 orders. And 7 species, 7 families 4 orders was found in highly urbanized area, the vicinity of Sang-Dong bridge. 5) As mentioned above, Based on A biota fundamental research, Close-to-nature stream restoration planning were full of suggestions: i) Designating ecosystem preservation area, ii) Making Close-to-nature stream revetments, iii) Making pool-and-riffle, vi) Making decks for observation and walks for nature experience, v) Creating wetland biotope. Through these methods, it is necessary to promote bio-diversity and lead people to the space for eco-learning.

The purpose of this study is on identifying the restoration guidelines of supplementary village grove and villageside forest in case of Neunggil village in Jinan county of Korea. These forests were managed very well before industrialization by village residents in order to obtain fuels and organic fertilizers traditionally. But recently, these forests were abandoned by using natural gas, oil and chemical fertilizer. Therefore, species diversity of these forests was downward and traditional rural landscape was lost. Accordingly, this study suggested the restoration guidelines of these forests through restoring the relationship between man and nature. For this, vegetation map was made by quadrat method. And management guidelines of these forests were suggested by the analysis of vegetation map. Also, for the restoration of supplementary village grove, Miyawiki professor's method of Yokohama university through introducing potential natural vegetation was suggested.

Although the demand and necessity for the facilities of nature environmental conservation and its utilization have been increased recently, the local governments has been experiencing difficulties to launch the facilities since there are no confirmed principles or guidelines for the direction of the facility and distinctions from the ordinary parks. In this regard, the aim of this paper is to provide the overall framework for establishing the facility by equipping checklists from planning to operational stage. The stages are disengaged into 5 steps of siting feasibility, planning, preliminary environmental assessment and environmental impact assessment, design, construction, and operation. This paper also include the recommendations to vitalize the existing facilities, of which expansion of educational program development; utilization of various manpower; provision of appropriate settings; strengthened monitoring; and increased public relations. Furthermore, it is suggested to consider the strengthened local characteristics, reviewing management plan at the stage of applying a new facility establishment to the concerned authority, fostering experts, and expansion of the facilities through restoration of environmentally damaged areas for a new facility.

Recently according to increasing of damage in creeks, it has been needed to develop a close-to-nature creek improvement technique considering flood safety as well as the functions of ecosystem and scenery preservation. In this study, the monitoring on creeks in seven provinces was accomplished to develop the technique applicable to domestic creeks between 2002 and 2007. Although the riparian ecosystem was disturbed, after just finishing the improvement on pilot creeks, the result of monitoring showed that restoration rates of creeks were satisfactory by constructing close-to-nature creek revetments. However it is hard to analyze on restoration and permissible tractive force of each revetments constructed in most creeks, because of insufficient monitoring data. Therefore the feasible study on the close-to-nature creek revetments should be performed in the near future through continuous monitoring on creeks.

This study was compared to the differences in the habitat, species composition and community structure of revegetation and nature area in Korea. Plant number in plot of revegetation and nature area was 10.3 and 15.0 taxa, respectively, and coverage was 90.6 and 88.1%, respectively. Revegetation and nature area was very heterogeneous, due to low similarity index (0.38) and less common plants. Festuca arundinacea frequency (56.7%) was highest in revegetation area, and Oplismenus undulatifolius frequency (66.7%) was highest in nature area. Plant appearing of revegetation and nature area was 111 and 136 taxa, respectively. Herb appearing of revegetation and nature areas was 93 (83.3%) and 72 (52.9%) taxa, respectively, tree was 18 (16.2%) and 64 (47.1%) taxa, respectively. Plant communities of revegetation area was classified into Lespedeza bicolor, Indigofera amblyantha, Alnus sibirica, Festuca arundinacea, Eragrostis curvula, Miscanthus sinensis, Humulus japonicus, Setaria faberii, Rudbeckia bicolor, Pueraria lobata community. Plant communities of nature area was classified into Pinus densiflora, Quercus aliena, Quercus acutissima, Quercus variabilis, Quercus serrata, Castanea crenata, Pinus rigida, Robinia pseudoacacia, Populus tomentiglandulosa, Phyllostachys bambusoides community. Habitat, species composition and community structure of revegetation and nature area showed a large difference.
