Purpose - Urban agglomeration construction is one of national strategic plans to accelerate the development of industrialization and urbanization in China, which has threatened the eco-environmental quality at the same time. This paper selected the urban agglomeration in the middle reaches of the Yangtze River as the research area. Research design, data, and methodology - The the slack-based measurement (SBM) model considering undesirable outputs is applied to measure the eco-efficiency of this urban agglomerations during 2006-2015. Results - The empirical results show that average eco-efficiency of the urban agglomeration in the middle reaches of the Yangtze River is 0.595. Regional ecological development is unbalanced. The highest eco-efficiency is recorded at Wuhan Metropolitan Area, and the lowest one is at the Changsha-Zhuzhou-Xiangtan City Group. Energy consumption and waste dust emissions are the key factors led to ecological inefficiency. Based on this, potentials for energy saving and waste dust reducing are calculated. Conclusions - Finally, this study provides policy implications targeted to promote the coordinating development of economy and eco-environment under the construction of urban agglomeration.

Seven soil samples were collected from paddy fields located nearby Nagoya city in Japan. All the soils were subjected to flooded condition and incubated with PCP at $30^{\circ}C$ for two months, and their anaerobic PCP degradation have been monitored by checking the PCP concentration of the soils at regular intervals. The degradation of PCP did not occur in the soils autoclaved two times before pre-incubation. On the other hand, all the soils showed significant PCP degradation in non-sterilized condition after 30 days of incubation, except far one soil sample (Yatomi), in which PCP was rarely degraded until 30 days of incubation. This result showed PCP disappearance in the pad(rf soils was mainly caused by microbiological activity, and depended upon the physicochemical characteristics of the soils.

Starting from the February 2008 till the end of November 2014, abundance of phytoplankton and their composition living in the coastal waters of Kyoungju city were investigated. Environmental and biological properties were also observed at 10 different stations on a seasonal basis. Due to the environmental variables, fluctuating pattern was appeared during the entire period of observation with different degree, as compared to those found in other costal waters in the East Sea. The concentration of phosphate was turned out to be very low which was even less than threshold level in the study area. Phytoplankton community structure was dominated by diatoms (both micro- and nanoplankton fractions) for several years and seasonal succession was also relied on the diatoms. The importance of dinoflagellates in the community was relatively low. Abundance of phytoplankton was heavily affected by physical factors in the surface water, however, affected more by chemical factors including nutrients in the deep water. For periods of this study, the phosphate concentrations was observed in an extremely low, which indicates that the main limiting factor affecting phytoplankton growth could be phosphate.

Rapid developments around the world have resulted in urban expansion, habitat destruction, habitat fragmentation, and pollution problems, which are the main reasons for the decline in biological diversity. The United Nations warns that many animals and plants will die out in the near future if this continues. This study was performed to propose a map of eco-corridor suitability analysis of Korean water deer(Hydropotes Inermis) to enhance biodiversity in Chuncheon city. Eight factors affecting habitat suitability were elevation, aspect, slope, forest type, distance to the road, distance to the stream, land use and green connectivity. Previous study analysis on the mobility behaviour of the Korean water deer(Hydropotes Inermis) produced a habitat suitability map by determining the threshold and assigning a value between 0 and 1 depending on the habitat suitability using the fuzzy function. A method of analysis was proposed for a number of eco-corridor through comparative analysis of the data from the produced habitat suitability map and the road-kill point. The previous studies were focused on Backdudaegan region and national parks except for urban cities. The potential habitat map of Korean water deer could be helpful as a way to prevent habitat disconnection and increase species diversity in urban areas.

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.
