본 연구는 강원도 평창 지역의 천연 활엽수림을 대상으로 입지유형별 임분의 생장 특성과 생태적 특성을 구명함으로써 각 임분 특성에 맞는 산림관리 방안을 제시하고자 하였다. 이를 위해 연구 대상지를 방위, 해발고도, 지형 조건에 따라 36개의 입지유형으로 구분하고 각 입지유형별로 직경 생장량과 직경 생장률 그리고 Shannon-Wither의 다양성지수, 균재도, 풍부도를 파악하여 임분의 생장 특성과 생태적 특성을 비교 분석하였으며, 이를 근거로 산림관리 방안을 제시하였다. 임분의 생장 특성은 방위에 따라서는 동쪽 사면과 서쪽 사면이, 해발고도에 따라서는 서쪽 사면을 제외하고는 해발고도가 낮아짐에 따라, 그리고 지형 조건에 따라서는 사면과 계곡이 양호한 생장 상태를 유지하고 있었다. 생태적 특성은 적정한 습도 조건을 유지할 수 있는 지역으로 방위별로는 북쪽 사면과 서쪽 사면, 지형 조건별로는 계곡의 종 다양성이 높게 나타난 반면 해발고도에 따른 일정한 경향은 찾아볼 수 없었다. 입지유형별 산림관리 방안은 남쪽 사면과 동쪽 사면의 경우 임목 생장과 생태적 특성을 함께 고려한 무육작업이 필요한 반면 서쪽 사면과 북쪽 사면은 생장 촉진을 위주로 한 밀도조절이 필요한 것으로 파악되었다. 해발고도에 따라서는 저지대는 생태적 특성을 고려한 무육관리가 필요하며, 고지대와 중지대는 직경 생장률이 2% 미만인 지역에 대해서는 생장 촉진을 위한 무육작업이 시급한 것으로 나타났다. 한편 지형 조건에 따라서는 남쪽 사면의 중지대와 고지대를 제외하고는 계곡의 생태적 안정성이 기장 양호한 것으로 나타나 친환경적 경영에 가장 적합한 지역으로 평가되었다.

The Ministry of Environment of South Korea has launched its plan to establish the National Ecological Institute. An International Symposium and Workshop was held at Ewha Womans University in Seoul on Thursday, 30 September 2010, to strengthen international cooperation, networking and partnerships for the conservation of biodiversity. This symposium was attended by experts of many major institutions for biodiversity conservation from South Korea and overseas. At the symposium and workshop preceded by a keynote speech by the renowned primatologist and conservation biologist Jane Goodall the participants discussed a wide range of topics including "biodiversity conservation: in situ and ex situ approaches", "conservation of species diversity and ecosystem management", and "international cooperation for biodiversity conservation and research". As a basis for future discussions, this article summarizes how the National Ecological Institute might contribute most effectively to public life and environmental management in South Korea and worldwide. It addresses the following issues: governance and funding, synergies within Korea, participation in international networks, external advice, a broad view of ecological issues, research agenda, building on identity, public outreach, and training the next generation of scientists.

The integration and management of various national ecological assessments are essential for the benefit of the public. In the Republic of Korea, the Ecological and Natural Map (ENM) serves as a comprehensive platform that synthesizes the results of national ecosystem surveys into a unified system interface. To provide the current status and characteristics of our policy, we analyzed the ENMs and related appeals from 2014 to 2022. Following their implementation, the ENM Guidelines underwent nine revisions, with most of the revisions pertaining to appeals. Nine public announcements were made regarding the ENM, resulting in a gradual expansion of the conservation area. The data also showed a consistent increasing trend in appeals. Most of the 1st-grade areas in the ENM regions where appeals were filed have significantly decreased. The larger area or the smaller population density of an administrative distinct, the more appeals were filed. Our study presents information regarding the current status of the ENM system. The analysis of the operational direction and indicator trends across the 16-year period since the establishment of the system provides valuable insights for similar systems.

DMZ is considered as an ecologically sensitive landscape and one of the highest biodiversity regions in the Republic of Korea. There have been, albeit the significant value, increased interests in developing this region for a variety of purposes including tourism and commemorative events. As this region has been already facing a range of problems derived from previous development, natural disaster and invasive species, the necessity for active management of ecological health within this region has been increased, which weighs the importance of executing ecological restoration. The objective of this study was to develop evaluation indices as an effective management means of properly evaluating ecological restoration and sustainably maintaining the restored conditions on a long-term scale. Through literature review existing evaluation indices related to restoration were collected, and then the most suitable indices were selected based upon two interviews and one questionnaire survey targeting experts in the relevant field to ecological restoration. They were categorized by two major division and their subclasses (Ecological base - vegetation structure & composition, habitat characteristics, soil environment; landscape ecology - connectivity, landscape patch, boundary & surrounding) and 40 indices. These indices were considered helpful to comprehensively evaluate ecological restoration on degraded environments within ecologically sensitive areas, and sustainably manage target areas by employing a long-term monitoring approach. As this result played a meaningful role in providing the fundamentals of evaluating ecological restoration, it should develop a suitable evaluation system through further research.

생태계는 우리의 생존과 삶의 질을 유지할 수 있게 하여 인간 복지에 직, 간접적으로 기여하고 있다. 그래서 생태적 기능의 계량화 방법이 필요하다. 본 연구에서는 응용생태공학에 생태계서비스를 도입하고 적용하는 것에 대하여 논의하였다. 하천의 경제적 가치, 도시 블루-그린-화이트 네트워크 구축, 생태복원 및 통합 물관리에 생태계서비스 개념 및 평가체계를 적용할 수 있는 방안을 모색하였다. 생태계서비스 개념 틀과 평가는 이해해당사자의 생태계 혜택 이해에 도움을 주고 응용생태공학 적용을 증가시켜 생태적 보호와 복원 가치의 증진에 이용될 수 있다.

최근 외래어종의 유입은 하천 내 어류 관리에 문제가 되고 있다. 최근 하천환경에 대한 인식이 높아지면서 하천변을 환경적이 기능을 갖도록 정비하는 사례가 많아지고 있다. 대저 생태공원은 4대강 사업에서 비닐하우스 등 관리하기 어려운 하천변 시설을 철거하고 조성된 지역이다. 조성된 대저생태공원은 철새도래지로의 의미와 수중생태계의 다양성을 제공하기 위한 하천공간으로의 환경적 요소를 고려한 정비로 설명할 수 있다. 이러한 자연친화적인 하천사업에도 불구하고, 외래어종은 환경공간을 파괴하고 하천 생태계에 악영향을 미칠 수 가능성을 가지고 있다. 본 연구는 낙동간 본류와 더블어 생태공원에서도 어류상 조사 및 우세종/외래어종 점유율 분석을 수행한 것이다. 대저생태공원은 정체지역으로 낙동강 본류와 수리적 특성이 다르므로 획득된 자료를 통해 생태공원의 외래어종 관리방안을 마련하는 것이 필요하다.

Ecological Engineering (EE) refers to all sustainable engineering that can reduce damage to ecosystems and that adopts ecology as a base and safety as an orientation in order to implement conservation of biodiversity and sustainable development. In short, EE attempts to safeguard the ecological environment while any essential construction projects proceed. EE encompasses many fields, including construction skills, ecosystem preservation, landscape, and even related cultures and so on. Such variety results in greater complexity of construction, and, consequently, indirectly increases the difficulty of construction quality control. The objective of our research is to explore a promising model for EE via an extensive literature survey. This model includes three principal stages: plan-design, construction, and maintenance, along with individual accompanying phases concerned with quality control and vital management. In this article, a river restoration example is adopted to describe in detail the critical points of quality control in the three stages (plan-design, construction, and maintenance) of the construction life cycle. This study proposes an integrated structure for quality management of EE to guarantee its quality and to enhance its core applications in order to achieve long-lasting preservation of the environment.

To protect water pollution and scarcity in lake and river, water quality monitoring applications have become important tools to understand the change of aquatic ecosystem. KLEON (Korean Lake Ecological Observatory Network) is designed to manage and share the ecological observations. The various kinds of water quality and phytoplankton observations are collected from the selected observatories such as seven lakes/rivers/wetlands. To deeply understand the collected observations with weather, KLEON also manages the observatory information such as lake, dam, floodgate, and weather. The accumulated observation and analyzed results are used to improve the water quality index of the observatories and encourage the ecologists' cooperation.

Parameter identification problem of a three species (predator, mutualist-prey, and mutualist) ecological system with reaction-diffusion phenomenon is investigated in this paper. The mathematical model of the parameter identification problem is constructed and continuous dependence of the solution for the direct problem on the parameters identified is obtained. Finally, the existence of optimal solution and an optimality necessary condition for the parameter identification problem are given.
