다국어 초록 (Multilingual Abstract)

This study is the result of an empirical analysis of Qili river in Hebei Province, China after constructing a landscape evaluation model using the Fuzzy-Delphi method and the DEMATEL-ANP method. After reducing the first 54 indicators to 40 indicators using the first questionnaire according to the Delphi method, as a result of the second questionnaire and data processing according to the expert Fuzzy-Delphi method, all evaluation indicators reached the convergence standard. After deleting the indicators whose median value was lower than the critical value, the final evaluation system for urban riverside revetment landscape was constructed centering on 22 indicators. The derived model is functional classification in four areas, namely in terms of water management, in terms of proximity to water, in terms of beneficial to water, in terms of protection of water, and functional, safety, landscape, ecological, and socio-economic aspects are classified into five criteria. The top five factors of the greatest influence of the evaluation indicators were River water landscape(C11), construction investment(C19), plant coverage(C16), hydrophilicity of the revetment(C10), and overall visual harmony(C9). However, considering that the weight of the factor of diversity of human landscape(C12) was the lowest, it was confirmed that the revetment landscape of urban rivers pays more attention to the interaction between natural landscape and waterscape, which almost excludes human landscape. On the other hand, in the urban landscape evaluation system, the order of the five rule layers was in the order of landscape aesthetics > ecology > socio-economics > function> safety, which was evaluated as a result of reflecting the overall landscape perception and attraction of the coastal landscape of the city's waterway. The overall landscape evaluation of the Qili river revetment is satisfaction at 70.93points, but urgent improvement is needed in Drowning rescue facilities(C6), Cultural landscape diversity(C12), and Embodiment of history, culture, and customs(C22) It turned out to be necessary.

국문 초록 (Abstract)

본 연구는 Fuzzy-Delphi법과 DEMATEL-ANP법으로 경관평가 모형을 구축한 뒤 하북성 형태시 소재 칠리하(七裏河)를 사례로 실증 분석한 결과이다. Delphi법에 따른 1차 설문지를 이용하여 최초 54개 지표를 40개 지표로 줄인 후 전문가 Fuzzy-Delphi법에 따른 2차 설문지 및 데이터 처리 결과 모든 평가 지표는 수렴기준에 도달하였다. 평가지표 중간값이 임계값보다 낮은 지표를 삭제한 뒤 최종적으로 22개 지표를 중심으로 도시 하천 호안지역 경관 평가체계를 구성하였다. 도출된 모델은 치수, 친수, 이수, 보수 등 4개 방면의 기능분류이며, 다시 기능적 측면, 안전성 측면, 경관적 측면, 생태적 측면, 사 회경제적 측면 등 5가지 기준으로 유형화되었다. 평가지표 중 영향력이 큰 상위 5개 요인은 수역경관 (C11), 건설투자(C19), 식물피복률(C16), 호안의 친수성(C10), 시각적 조화(C9) 순이었다. 그러나 인문 경관의 다양성(C12)요인의 가중치가 최하위임을 볼 때 도시 하천의 호안경관과 인문경관은 거의 배 제된 상태이며, 자연경관과 수역경관의 상호작용에 더 많은 관심을 기울이고 있음이 확인되었다. 한편 도시 경관평가 체계에서 5개 준칙층의 순서는 경관 미학성> 생태성 > 사회경제성 > 기능성 > 안전성 순으로 나타났는데 이는 도시 내 수로의 호안 지역 경관의 전체적인 경관 감지와 흡인력을 반영한 결과로 평가되었다. 칠리하 호안구역의 종합적 경관 평가치는 70.93점으로 만족스러운 수준이지만 익수사고에 대비한 구조시설(C6) 인문경관의 다양성(C12) 그리고 역사문화 풍습의 구현(C22) 항목에 있어서는 시급한 개선이 필요한 것으로 밝혀졌다.
