  • This study aims to analyze civil society consciousness to river projects, examine the current state of resident participation, and suggest development directions for river policy. For this, this study conducted a survey of 1,200 local residents and 100 public officials living and working in the river project areas. The result demonstrates the necessity of formulating river policy in a way that recognizes voices of various policy stakeholders, strengthens partnership among resident groups, and promotes a trend shift in river restoration to reflect residents' consciousness.

  • 우리나라 하천관리의 패러다임은 1990년대 이후 기존의 치수 및 이수능력을 고려함과 동시에 하천환경의 보전 및 복원을 새로운 목표로 설정한 자연친화적 방식으로 변화되었다. 하천법령 및 제도적 측면에서도 수자원 장기종합계획 및 유역 종합 치수계획은 하천의 환경보전 및 다목적 이용계획을 포함하도록 규정하고 있으며, 국내 하천법에 따르면 하천기본계획 수립 또한 자연친화적 하천조성 및 이와 관련된 보전지구 지정 등을 포함하도록 규정하고 있다. 하천설계기준, 자연 친화적 하천관리에 관한 통합지침, 또는 수자원 장기종합계획에서 적용하고 있는 하천환경조사 및 평가지표는 서로 다를 뿐만 아니라 과학적인 근거가 명확하지 않는 등 국가차원의 표준화가 이루어지지 못한 상태라 할 수 있다. 1990년대 이후 미국, 독일, 영국, 호주 등 선진국들은 하천환경 복원사업의 추진과정에서 복원사업의 타당성 제고 및 성공적인 사업수행을 위하여 그들 국가의 하천특성에 적합한 하천환경 평가 체계를 구축한 바 있으며, 이들 평가체계는 새로운 과학적 지식과 기술의 축적에 힘입어 지속적으로 발전되고 있다. Fujita의 유형화(Segment 분류)법에 의하면, 하천구간(Segment)은 하상경사, 하상재료, 식생, 생태 등이 통계적으로 동질인 하천 구간으로서, 하도 특성과 하천생태계 공간을 구분하는 단위이다. 자연하천에서 동일한 경사를 갖는 하천구간은 하상재료, 소류력, 저수로 폭, 수심 등이 대체로 동일한 값을 나타내고 있으며, 하도 특성을 지배하는 주요 인자로 각 하천의 평균 연최대유량, 하상재료의 대표입경, 하상경사 등을 설정하고 있다. 본 연구에서는 하천구간을 유형화하는 기준을 하상경사로 적용하여 평가단위를 분류하였으며, 평가체계는 미국의 USEPA를 한국형 하천환경에 맞도록 수정보완 하였다. 특히 미국의 USEPA의 지표 중 하안영역의 식생피복, 하반림 등은 생물분야 식생영역과 상충되어 제외하고 우리나라 특성에 적합한 하천횡단형상, 하천횡단 구조물 등의 평가기준을 재정립하여 내성천에 평가적용 분석하였다. 하천환경의 수리 및 하도 특성 평가기준 개발에 따라 평가체계의 개념적 틀을 토대로 통합적이고 표준화된 한국형 하천평가기준 개발을 위한 방법론을 정립하고, 나아가 하천환경의 지속가능성을 전제로 한 하천복원사업의 장 단기적 성공 여부를 평가할 수 있는 실무지침의 과학적 근거를 제시하고자 한다.

  • This study aims to obtain basic data for systematic restoration by analyzing the monitoring results of the Shimwon Valley Ecological Landscape Restoration Project area in Jirisan National Park. In 2017, when the restoration project was completed, 12 monitoring plots and 4 control plots were installed for vegetation monitoring, and changes in the relative dominance, species diversity index and similarity between 2017 and 2020 were analyzed. The species diversity index of the surveyed areas where trees were planted during the restoration project was 0-1.4552, and the similarity index with the control group was 0% except for one survey area at 1.32%. The very low species diversity index and similarity index in the survey areas were attributed to the loss of trees planted during the restoration project due to death, damage by wild boars, or erosion by running water. On the other hand, the species diversity index was 0.9538-2.3222 in the monitoring plot where no tree was planted, and the similarity index was analyzed to be as high as 8.33%. It is necessary to continue the long-term monitoring for the development of ecological landscape restoration methods in the national park and analysis of the succession in monitoring plots where no trees were planted.

  • 이번 글부터는 다시 도시지역에서의 복원 기법과 사례를 소개하고자 한다. 지난 글에서는 서울 공고 생태연못을 대상으로 하여 소개하였다. 우리나라에서는 처음으로 도심내부에서 소규모로 생물다양성을 증진시키기 위한 실험사업이었다는데 의의를 찾을 수 있다. 물론, 최초로 조성된 사업이기 때문에 보완해야 할 것도 많은 곳이었다. (중략)

  • To assess an economic value of Cheonggyecheon river restoration project, an in-depth exit survey data was collected to apply travel cost method in this study. Poisson model, Negative Binomial, Zero-truncated Poisson, and Zero-truncated Negative Binomial model were executed due to the nature of count data. Empirical results showed that regressors were statistically significant and corresponded to general consumer theory. Since our survey data showed over-dispersion, Zero-truncated Negative Binomial was selected as an optimal one to analyze travel demand of Cheonggyecheon by model goodness of fit test among those aforementioned empirical models. Estimating an economic value of Cheonggyecheon river restoration project, which is known as an ecological river restoration project, we used annual visit of individual traveler and an optimal model. Suffice to say that the annual economic value of Cheonggyecheon river restoration project was estimated as 193.4 billion won in 2013.

  • This study was conducted to identify items that should be considered in order to increase user satisfaction in the Jayeonmadang project by analyzing the importance and satisfaction targeting Gochang Jayeonmadang users. As a result of analysis on the importance and satisfaction of Gochang Jayeonmadang users focusing on 20 items in 6 fields, Overall, it was analyzed that they were not satisfied as they were important. In order to increase user satisfaction of Gochang Jayeonmadang, maintenance such as 'cleanliness and hygiene', 'water quality', 'vegetation growth', and 'facility management' should be carefully reflected from the planning and design stage, and careful attention should be paid even after the project. In addition, emphasis should be placed on enhancing the user convenience, such as 'accessibility', 'space layout and utilization efficiency', and 'convenience of route'. And, when promoting the Jayeonmadang project, the purpose of the project should be actively promoted to local residents to raise the residents' awareness of the importance of biodiversity in the city.
