Recently, there is an increasing criticism both inside and outside China toward the eco-migration projects. The author focuses on the eco-migration of Sanjiangyuan National Nature Reserve as a case study as it is one of the main eco-migration projects. At the end of 2010, government invested 4.47 billion CNY in eco-migration and relocated the immigration 55773 people in 10733 units. Benefits of eco-migration is obvious, however, it needs to be recognized that in the aspect of environment justice, it is unfair to sacrifice a group of people in the process of environmental protection because costs and benefits result from the environmental protection have to share among the people without discrimination. Local herdsmen received extra disadvantages in their level of material possessions, social and cultural values and the social inclusion after eco-migration project. As a part of the eco-social system established within several centuries, the local herdsmen are not only threateners to local ecology system, but also the guardians to the natural environment through religion and habits last for generations. The social and cultural values, traditional religion and Nomadic living habits, as important as the environment, are need to be cherished and protected.

Eco-village is emerging as one of housing styles in the modern age. The common space in Eco-village uses environment-friendly materials while residents appear to aspire to a community. The common space in Eco-village offers a place of interchange and interaction for both visitors and residents as a transit area connecting dwelling units. It also forms the sense of community and serves as a space that builds friendly relations among residents. However, there seems to be a lack of research compare to its various roles and importance for this common space, which is an significant factor in establishing Eco-village plans. The purpose of this study is to provide research data by creating a layout drawing of Eco-village and reveal the characteristics of space boundary and practical use of common space through case studies on villages. This will serve as actual data in designing common space which would correspond to the purpose of Eco-village planning.

Vegetation processes have a significant impact on rainfall runoff processes through evapotranspiration control, but are rarely considered in the conceptual lumped hydrological model. This study evaluated the model performance of the Hapcheon Dam watershed by integrating the ecological module expressing the leaf area index data sensed remotely from the satellite into the hydrological partition module. The proposed eco-hydrological model has three main features to better represent the eco-hydrological process in humid regions. 1) The growth rate of vegetation is constrained by water shortage stress in the watershed. 2) The maximum growth of vegetation is limited by the energy of the watershed climate. 3) The interaction of vegetation and aquifers is reflected. The proposed model simultaneously simulates hydrologic components and vegetation dynamics of watershed scale. The following findings were found from the validation results using the model parameters estimated by the SCEM algorithm. 1) Estimating the parameters of the eco-hydrological model using the leaf area index and streamflow data can predict the streamflow with similar accuracy and robustness to the hydrological model without the ecological module. 2) Using the remotely sensed leaf area index without filtering as input data is not helpful in estimating streamflow. 3) The integrated eco-hydrological model can provide an excellent estimate of the seasonal variability of the leaf area index.

Natural resource of the island and coastal regions is one of the most important element of ecological network system in Korea. Currently, there is trend that natural and biological resources such as fishing and tidal wetland have been used to local economic activation in island and coastal regions. According to the 5-days work in a week, island and coastal regions become important amenity resource of citizen's recreation area. Korea is peninsula surrounded by maritime. Especially, South and West Sea surrounded by many islands and tidal flat wetlands are emerging marine ecosystem and seascape in the world. Natural resource is limited, so we have to sustain those resource to current tourism. In this study, I would like to suggest that importance of cultural resource as well as natural resource for 'eco-cultural tourism' in order to keep both biological diversity and cultural diversity as amenity resource for future island economic activation in Korea.

Marine algal flora and community structures were examined seasonally at three sites around the Shingori Nuclear Power Plant, Korea from February to November 2016. A total of 76 species were identified, including 9 green, 14 brown and 53 red algae. The greatest number of species occurred at Daesongri (51 species) followed by Sinamri (43 species) and at the discharge area (38 species) during the study period. Of the 76 seaweeds, 59 annuals and 17 warm tolerant species were recorded. Annual average biomass in dry weight varied from $168.02g/m^2$ at the discharge area to $222.53g/m^2$ at Sinamri. The coarsely branched form was the dominant functional form of seaweeds at the three sites. Seaweed community structures at the discharge site were distinguishable by decreasing species richness, biomass, species diversity index, richness index, and evenness index. The ratio of warm tolerance species and the dominance index values were remarkably higher at the discharge than those at the other sites.

The purpose of this study is to evaluate the creation techniques of eco-pond, one of biotopes to promote biodiversity in urban residence area. Investigation were classified out plant, mammals, amphibia, reptiles, birds, fishes and insects. The results were summarized as follows: Around the eco-pond shows simple vegetation structurs, consisted of Pinus densoflora S et Z. and Robinia pseudoacacia under competition. In case of shrub, consisted of 4 species but plant growing appearence diversely by seasons. The evaluation of vegetation of eco-pond, there are found 4 species of aquatic plants. Inside the revetment of pond, Echinochloa crus-galli, Persicaria hydropiper, Digiaria sanguinalis, Cyperus microiria and Bidens frondosa L. are mainly distributed. Near the revetment, Trifolium repens L. and Digiaria sanguinalis are prevailed. And in its background, Erigeron canadensis, Erigeron annuus and vines are begins to make their appearances. When evaluation animals in eco-pond and contrast plot, it show simple species and numbers of mammals. It seemed to be resulted from its isolation and outside intervention by users In eco-pond, Pica pica and Streptopelia orientalis are mainly found and in contrast plot of Columba livia, which are so strong adaptation to city life environment. In case of amphibia and reptiles, none is observed in contrast plot, but in ecological pond, Rana nigromaculata and Hyla japonica are constantly observed. In case of insects, more species are found in eco-pond than contrast plot. And in eco-pond, more dragonflies are visibly increased one year after its construction. In floral zone inside of pond revetment, grasshopper and Locusta migratoria are frequently observed. In case of butterflies, they are mainly found in log fence and willow(salix) around eco-pond. In case of fishes inside of eco-pond, the species and its density are remarkable increased one year after the construction. With above evaluation results, we have identify the increase effect of biodiversity after construction of the eco-pond.

We recorded the movement of wildbirds nine times at Hoam 1st Tunnel, Kkachisan Park, Deungneung pass to compare the movement between eco-corridor and neighboring crossing road from June to September, 2006. Among three areas, birds did not prefer the eco-corridor at pass type such as Kkachisan Park and Deungneung pass, however number of species and individuals were high at the eco-corridor at Hoam 1st Tunnel. Over 90m width and the slope location of eco-corridors can be beneficial for wild birds to enhance the movement along eco-corridors between isolated two patches. Average foliage volume under two meters showed the relation with bush nesters, and that from 7 to 8m had the highest relationship with canopy nesters. In Seoul city, target species should be considered at the construction of eco-corridors according to site characteristics, but Paradoxornis webbianus could be suggested as a main target species at eco-corridors. To enhance the movement of diverse wildbirds, we would implement that eco-corridors could be located at the slope area with the size of 1ha (over 90m width), eco-corridors could be planted and managed with the high foliage volume of shrub layer under twometers and canopy layer over 8 meters.
