  • This study was conducted to establish ecotourism as an introduction to sustainability and international cooperation. As a plan to retain the original meaning of ecotourism, the introduction of a program to certify/designateecotourism is being vitalized in many countries around the world. In Korea as well, an agenda to the introduction of an "Ecotourism Designation System,"which aims to ensure the quality of ecotourism at a certain level, was submitted by the Ministry of Environment to the National Assembly in June 2011, and the promotion for a demonstration program is planned this year to introduce the system. Japan has been carrying out the certification systems Good Eco-tour, which certifies the sustainability of ecotourism providers and accommodations since 2006, respectively, and has been securing the sustainability of ecotourism by enactment in 2008, as the world's first law to promote ecotourism. And the second general conference of the first Global Partnership for Sustainable Tourism(GPST) was held in Korea in March 2012, particularly, there was an agreement that the promotion of Asia and the Pacific Area Network for sustainable tourism would center around Korea, and accordingly, it is expected that Korea's status as a core country for ecotourism in the Asia-Pacific Area will increase. While the demand for an approach to natural resources is rapidly increasing, we should be active in providing an institutional strategy such as a designation system to secure the sustainability of ecotourism and seeking a plan for cooperation and network vitalization in the Asia-Pacific Area where similar natural resources and cultures are shared.

  • 최근 몇 년 사이에 자연친화적인 하천복원의 관심이 고조되면서 자연형 하천공법의 적용 초기단계를 걷고 있는 우리나라에서는 생태계 복원과 더불어 인명과 재산을 보호할 수 있는 안전한 자연형 하천 공법의 개발을 위해 수리적 안전성을 지속적으로 관찰하고 분석할 필요가 있다. 그러나 아직까지 우리나라에서는 수리적 및 치수 방재적 측면에서 자연형 하천공법의 안전성에 대한 표준화되고 일관된 분석체계가 아직 구성되지 못하여 자연형 하천정비 공법의 실무적용에 많은 어려움을 겪고 있다. 더구나 소하천 유역은 지역적 특성이 두드러지고 계절에 따른 유량변화가 심하여 하천의 수리적 안전에 대한 분석체계가 적절하게 갖추어지고 있지 못하는 실정이다. 따라서, 본 연구에서는 자연형 하천공법에 따른 소하천의 수리적 안전성과 하천정비 전$\cdot$후의 치수기능의 변화를 Hec-Ras(river analysis system)를 이용하여 적용대상 유역의 수리$\cdot$수문학적. 기하학적, 기상학적 자료들 기본으로 대상유역에 모의해 보았으며 그 결과로부터 자연형 하천정비 전$\cdot$후의 수리적 안전성을 해석하고 하천의 치수기능에 대한 자료를 얻고자 하였다. Hec-Ras를 이용한 연구의 결과 값들은 국내에서의 자연형 하천공법 적용에 따른 하천의 수리적 안전성을 판단하는 표준화된 분석체계를 마련하는데 기초 자료를 제공할 것이며 자연형 하천정비의 기준과 적용을 확립하는데 중요한 의미를 가질 것으로 판단된다.

  • The purpose of this study is to examine distribution and damages of the trails of inquiry of urban natural parks. Those parks were located at south-north green corridor at Incheon being mountainous type of urban natural parks that were core area of urban ecosystem preservation to of urban natural parks that citizens recently made use of them as nature experience type of leisure and recreation place from time to time, and to supply basic material deciding on the ways to improve the trails of nature preservation type. The survey sites included Geyang Park, Baekma Park, Yaksa Park, Munhak Park and Cheongryang Park. The number of main trails was 42 at Geyang Park, 43 at Baekma Park, 9 at Yaksa Park, 28 at Munhak Park, and 22 at Cheongryang Park, and it was excessively more than optimum needed: The number of branch trails of the parks seemed to increase. The bared trail width in average of the roads was 3.5m, while maximum depth in average was 21.3cm. The trails were thought to be deteriorated rapidly without systematic maintenance. The 5th and 6th grade of the impact rating class that required restoration because of serious deterioration occupied 19.6∼78.0%. Based on the findings, the study suggested ways to improve and manage the trails of inquiry of urban natural parks that were placed at south-north green corridor at Incheon.

  • 최근 도시화 및 불투수면의 증가와 지하수의 과다한 사용으로 직접유출이 증가하고, 침투량이 감소하며, 하천의 건천화가 발생하고 있다. 이에 환경부에서는 이러한 물순환의 왜곡을 막기위해 물환경보전법상의 물순환율을 정의하고 물순환 관리목표를 설정하였다. 하지만 지역 별 물순환 특성을 반영한 관리계획이 부족하고, 현재 제한된 재원의 효율적 활용을 위해서는 물순환 관리지역에 대한 우선순위 결정도 필요하다. 본 연구에서는 PSR framework를 통해 유역 물순환 평가방법론을 만들고 이를 활용한 지역별 관리계획 및 우선순위를 결정하고자하였다. PSR framework는 지속가능성을 위해 OECD가 개발한 개념 모형이며, Pressure, State, Response 세 가지 요소로 구분해 평가하게된다. PSR framework의 기본 개념은 인간의 활동들이 환경에 압력 (P)를 주고, 이로 인해 자연의 질과 영향 (S)을 미치며, 이에대한 회복을 위해 인식과 행동을 통해 정책과 제도 등을 통해 반응 (R)한다는 것이다. 유역 물순환을 4가지 그룹 (기후, 수문학적, 사회경제학적, 환경적)으로 구분하고 각 그룹 별 평가요소에 대하여 도출하였다. 기후그룹은 강우, 수문학적 그룹은 증발산, 토지이용, 유출특성을, 사회경제학적 그룹은 재정, 사회구조, 기반시설, 정책을, 환경적 그룹은 수질, 수생태계를 선정하였다. 이후 각 요소 별 평가를 위해 다양한 지표를 고려하여 선정하였으며, 각 지표를 PSR framework에 맞춰 재분류하였다. 각 지표를 하나의 점수로 통합하기 위해 지표 별 가중치를 산정하였으며, 이때 연구자의 주관이 반영되지않는 엔트로피 기법을 이용하여 산정하였다. 구한 식을 통해 우리나라 소유역구분을 기준으로 모든 지표를 계산하였으며, 각 지표에 가중치를 적용해 유역 종합점수를 산정하고 유역 별 취약지역 및 취약요소를 평가하였다.

  • This study was conducted to clarify the breeding ecology of tits Parus spp. used artificial nest boxes in a deciduous forest at the Ansung Campus, Chung-Ang University from March through July, 2006 to 2010. Varied tit Parus varius, marsh tit P. palustris and great tit P. major bred in artificial nest boxes during our study period. There were no differences in number of breeding bird pairs among different entrance diameters of artificial nest boxes. The number of breeding pairs of great tits was the most highest among tits and that of varied tits was the least. Great tits mainly used 40 mm and 35 mm artificial nest box entrance diameter and marsh tits preferred 30 mm entrance diameter. In three tits species, there were differences in first egg date, clutch size, brood size, egg incubation period, nestling care period and breeding success among study years. It is needed the study on long-term ecological research about breeding ecology of tits related with habitat conditions.

  • The Yellow Sea Ecoregion Conservation Project is a joint international project which is carried out under the purposes of conserving the habitats in the Yellow Sea Ecoregion and biodiversity from various threats that damage ecosystems, informing the importance and value of the Yellow Sea Ecoregion, and promoting the understanding and interests of Korea, China and Japan. Subsequent to the Yellow Sea Ecoregion Planning Programme which had been performed during the period from 2002 to 2006, the Yellow Sea Ecoregion Support Project has been performed over 7 years in total from 2007 to 2014. Panasonic is sponsoring the financing of the project, and the organizations in charge of the project by country are Korea Institute of Ocean Science & Technology for Korea and World Wide Fund for Nature branches for China and Japan. While the Yellow Sea Ecoregion Planning Programme was focused on the biological assessment and the selection of potential priority area by scientific review, the Yellow Sea Ecoregion Support Project is oriented toward practical activities targeting more diversified stakeholder. Especially, this project plans to support direct conservation activities in the region and participation and cooperation from local residents. The project plan is comprised of 3 phases. During the first period from 2008 to 2009, small grant projects were operated targeting 16 institutions of Korea and China, and for the second period from 2010 to 2012, one place each was selected as demonstration site for habitat conservation in Korea and China respectively and supported for three years to introduce the conservation method based on international standards such as the management of marine protected areas, ecosystem-based management and community-based management and simultaneously to develop habitat conservation activities suitable for national and regional characteristics. During the period from 2013 to 2014 which is the last phase, the project plans to distribute the performance of small grant projects and demonstration site activities through a series of forums among stakeholder. Through the activities described above, the recognition of general public on the conservation of the Yellow Sea Ecoregion was changed positively, and community-based management began to be reflected in the policies for the marine protected areas of central and local government.

  • The aim of this research is to set a systemic Ecological Landscape Planning Model to cope with the destroyed landscape problems which was caused by massive development project and thoughtless development in country areas. The summary of research result are as follows. As a result of analysis on domestic and international literature, there are 60 planning index items which are nature conservation area, landscape conservation area, and build and manage wetland biotope and so on. total number of planning index is 34 after finalizing the physical index items. As a result of on-spot research, all 34 planning index after literature analysis is existing. Also, there are 38 finally-selected index which includes 4 added planning index in the process of research like natural vegetation in frequently-used spot. As a result of importance analysis on detailed planning index, most are above 5 points, which is relatively high. As a result of factor analysis on patterning for the detailed planning index, it was classified with seven elements. The first Ecological Landscape Planning model was set with integrated analysis on result of pattering for the detailed planning index and importance of detailed planning index. Based on first model, to make more systematic landscape, the analysis of MCB was conducted. As a result of MCB analysis according to planning index, it is confirmed that each planning index shows maximum. As a result of importance analysis on the 9 plans keynote, the average importance point was 4.62 for conservation area and 4.54 for enrichment area respectively. By integrating the result of importance analysis on basic aims of the first model, MCB analysis and plans, we set the second Ecological Landscape Planning model. In vertical transition, for example, 'conservation area' showed the importance point above 5.2 for all planning index except setting recreational space. Also, the analysis on parallel structure showed that relation between 'additional improvement, management, and connection' and other planning index is above 5.3 and importance on correlation with 'the part which should be protected from nature and landscape' marked 6.07 which is the highest.

  • 경제개발에 따른 현실적인 하천의 모습은 각종 오염원으로 인한 수질악화와 산업화 및 도시화에 의한 물순환시스템의 붕괴로 인한 하천 생태계의 파괴로 나타나고 있다. 따라서 훼손된 하천을 친자연적으로 보존하고 더 나아가 하천을 자연생태계와 인간이 공존할 수 있는 공간으로 조성하기 위한 시도가 늘어나고 있다. 2006년 수립된 수자원장기종합계획에서는 자연환경보존과 생활환경 개선을 위한 유량확보의 필요성을 제기하고 있다. 이중 생활환경개선에 필요한 물은 청계천의 사례처럼 최근 들어 하천 및 수변생태계 복원, 보전 사업과 연계된 거주성(Amenity)차원의 새로운 용수수요로써 급격히 증가하고 있는 실정이다. 이러한 환경개선용수는 인위적으로 공급되기 때문에 환경개선용수를 필요로 하는 구간의 상 하류의 자연적인 물순환시스템에 영향을 미치게 되어 하천수 사용에 대한 수리권에 직접적으로 영향을 주게 된다. 따라서 환경개선용수를 사용하고자 하는 경우에는 이를 공급하는 공급원 지점과 환경개선용수를 사용하는 구간을 중심으로 상세한 물수지분석을 통해 기존의 수리권에 대한 영향 여부를 검토하여야 한다. 새로운 수요인 환경개선용수는 하천의 일부 구간 또는 일부 지역에 대해 거주성(Amenity) 차원에서 사회환경을 개선 정비하는데 활용하기 위하여 수혜자의 요구에 의해 인위적으로 공급되는 용수인 것이다. 따라서 국가가 산정하는 하천유지유량과 달리 환경개선 용수는 수혜자가 직접 산정하여야 하며, 산정된 환경개선용수는 하천관리자(국가)로부터 사용허가를 받아야 한다.

  • This study was carried out to evaluate the physicochemical properties of different types of topsoil in forest ecosystems by damage pattern and analyse the possibility of using the topsoil as a planting ground construction material. There were 72 samples from 36 sites of 12 damaged areas and 36 sites of 12 non-damaged areas. The results showed that the physicochemical properties of topsoil from non-damaged areas of forest ecosystems were on an average clay loam~sandy loam in soil texture, showing $0.95{\sim}1.10Mg/m^3$ in soil bulk density, $35.7{\sim}44.0m^3/m^3$ in solid phase, 56.0~64.3 in soil porosity, 8.4~35.8% in aggregate stability, 5~13 mm in soil hardness, 5.3~6.1 in pH, 0.14~0.65 dS/m in EC, 0.28~0.42% in T-N, $14{\sim}22cmol^+/kg$ in CEC, $0.15{\sim}0.31cmol^+/kg$ in Ex. $K^+$, $2.07{\sim}2.84cmol^+/kg$ in Ex. $Ca^{2+}$, $0.45{\sim}1.97cmol^+/kg$ in Ex. $Mg^{2+}$, 17~96 mg/kg in Av. $P_2O_5$ and 3.2~5.6% in OM. On the other hand, damaged areas were on an average clay loam~loamy sand in soil texture, showing $1.54{\sim}1.75Mg/m^3$ in soil bulk density, $52.8{\sim}58.0m^3/m^3$ in solid phase, 42.0~47.2 in soil porosity, 4.2~22.5% in aggregate stability, 13~25 mm in soil hardness, 4.8~5.5 in pH, 0.13~0.62 dS/m in EC, 0.02~0.12% in T-N, $5{\sim}15cmol^+/kg$ in CEC, $0.11{\sim}0.18cmol^+/kg$ in Ex. $K^+$, $0.45{\sim}2.36cmol^+/kg$ in Ex. $Ca^{2+}$, $0.39{\sim}0.96cmol^+/kg$ in Ex. $Mg^{2+}$, 15~257 mg/kg in Av. $P_2O_5$ and 0.4~2.2% in OM. After conducting a comparison of physicochemical characteristics of non-damaged forest area and damaged areas, it was found that the physicochemical characteristics of damaged areas were more deteriorated compared to that of non-damaged areas. Therefore, it is judged that it is necessary to establish countermeasures for the conservation and management of the damaged areas for topsoil recycling in the future.
