  • Lately, besides promoting the biodiversity of the natural ecosystems, there is a demand for climate change mitigation features that will reduce greenhouse gases and prevent disasters that will bring damages such as torrential rains. However, there was not a lot of discussion on the soils that are key in these features. Therefore, this paper proposes a network (Gold Network) as an alternative that will solve the problem that was filed earlier by figuring out how to compose the soil environment. First, in order to maximize the ecological status and value of the soil, a soil network can be proposed through the vertical and horizontal connections of the fragmented soil. Second, there is a need to understand and research the organic system of the ecosystems as well as the complex perspective of the ecosystem services, not only the fragmentary perspectives of the soil remediation, planting improvements or the other existing elements. Third, there is a need to apply the integrated perspective of the Landscape Ecology, Ecological Engineering and Restoration Ecology for the connectivity of the soil (network) due to it being in the execution of the soil network. If a soil network was to be built, a fundamental ecological network would be realized to not only promote biodiversity but also to prepare effective adaptation to climate change.

  • DMZ (De-Militalized Zone) in South Korea is world heritage area by passage control of human-being for more than 50 years since 1953. Wild flora and fauna in these area have been protected from any development and/or habitat destruction. However, consideration on ecosystem and nature in the area is becoming higher, and demand for development is raising also. We have reviewed any publications, which are surveyed about ecosystem and interview local residents about wildlife inherit there. Totally 51 species have been reported inhabited DMZ belonging to 17 Families, 6 Orders, so far. National monuments in DMZ are following; Asiatic black bear (Ursus thibetanus), Eurasian otter (Lutra lutra), Musk deer (Moschus moschiferus), KOREAN goral (Nemorhaedus caudatus), flying squirrel (Pteromys volans) and spotted seal (Phoca vitalima). These results would be an essential data to establish management strategy and manuals for conserving native ecosystem, native flora and fauna in DMZ, and also using for registering world heritage area under UNESCO.

  • An-yang stream is a branch stream connecting to Han river and regarded as a national stream. This study chose the representative stream of An-yang and identified vegetation and flora. The ecological survey aimed at identifying indicator of urban streams for measuring to protect urban areas and to promote wetland conservation. A total of 266 species were identified into 35 Orders, 78 Families. The introduced species of Sicyo angulatus need a special treatment to reduce the population. The wetland vegetation is quite various and we suggested 11 different vegetation zones depending on introduced species and amenity between human and nature, This will lead to blue-network to crease favorable environment and manage important species for this region.

  • Due to a decreasing tendency of river runoff in the Laohahe River basin in North China, quantitative analysis was made with the aid of the conceptual Xinanjiang model under the background of nature climate variability as well as human-induced climate change according to the long-term observational hydrometeorological data. In the past, the human effect on surface water resources was estimated by investigating the impact of human activities on each item in the equation of water balance, so as to calculate water quantity of each item in the original natural status. It seems to be clear conceptually. It is appropriate just for the case of direct impact, such as water transfer from one basin to another, water storage by various scales of hydraulic projects, besides a huge amount of investigation and indeterminate statistics data when applied in practice. It is difficult for us to compute directly water consumption due to the implementation of measures for soil conservation, the improvement of farming techniques in agriculture, the growth of population in towns and villages, and the change of socioeconomic structure. In view of such situation, the Xinanjiang model was used to separate human impact from the climatic impact on water resources. Quantitatively human activity made river runoff decrease by 1.02, 50.67, 58.06 mm in 1960's, 1970's, 1980's, respectively, while by 97.2 mm in 1990's in the sense of annual average in the Laohahe River basin.

  • Land-use changes have made considerable impacts on humans and nature such as biodiversity and ecosystem services. It is recognized as important elements for land use planning and regional natural resources conservation to identify the major causes of land use changes and to predict a process of changes and effects. This study, by using a spatially explicit Dyna-CLUE model, analyzed correlations between driving factors, quantified location characteristics of different land use types using logistic regression analysis and examined future land use changes and its effects in Yangpyeong and Yeoju region. We expected land use changes based on the three scenarios with different future land demands and simulated future changes for spatial variations of land use for the 20 years. The outcomes shows that larger change was found in agricultural areas than forest areas, based on the change in built-up areas. The changes in forest areas, which were mainly occurred in edge area, were expected to affect a large impact on its ecotone. It was found to be the importance of the management of forest edge and the necessity of the environmentally sound and sustainable development in order to conserve natural resources of the region.

  • 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.

  • Assessment of soil erosion is a cost and time-consuming task. There are many models developed to predict soil erosion from an area, but Universal Soil Loss Equation (USLE) is most widely used empirical equation for estimating annual soil erosion. Soil erosion depends upon-rainfall intensity, type of soil, land cover and land use, slope degree, slope length and soil conservation practice. All these parameters are have spatial distribution and hence satellite remote sensing and Geographic Information System (GIS) are applicable in the assessment of the influence on soil erosion. GIS has been integrated with the USLE (Universal Soil Loss Equation) model in identification of rainfall-based erosion to the Bocheong River which is the representative basin of IHP due to Typhoon Rusa. Similar studies are available in literature, ranging from those that use a simple model such as USLE to others of a more sophisticated nature.

  • This study is a basic study of the stone cultural landscape resources of Jeju Island with the value of world heritage. It has the ultimate purpose of providing basic resources for the advantages of various Jeju local resources and future conservation and management. Literature research and field survey were conducted to derive the landscape characteristics of Jeju stone cultural resources. and Research for recognition of stone cultural resources and image analysis were performed in parallel. Accordingly I would like to consider the recognition of the Jeju stone cultural landscape held by Korean and Chinese. As a result of the research, Stone is a typical local resource in Jeju, and the greatest feature of the stone was its natural nature. and In the image of the cultural resources of stone, he highly appreciated the image of "Harmonious", "Attractive" and "Unaffected". Recognized Field walls as "Beautiful" and Dolhareubang as "Familiar". And the most preferred stone cultural resources in Korea and China are surveyed in order of Field walls and Dolhareubang, and you can see that there is a difference between them in the evaluation.
