Abstract

This study analyzed the satisfaction of green infrastructure around 39 dams, including multi-purpose dams, water dams, and flood control reservoir dams, to induce space improvement in terms of sustainability, and the results of the study are as follows. First, the satisfaction level based on the Likert scale of 5 points for the currently created dam green infrastructure was 3.76, and there were differences depending on the respondents' gender, age, residence, number of dam visits, and the need to pursue sustainability, and it was analyzed to be statistically significant. In the case of gender, p<.05, age, residence, number of dam visits, and the need to pursue sustainability were found to be p<.01. Regression analysis was conducted to confirm the effect of these respondents' characteristics on satisfaction, and it was analyzed that only the number of dam visits and the need to pursue sustainability had a statistically significant effect, and other characteristic variables had no significant effect. Second, in terms of satisfaction with the conceptual image of public bridge, view place and play space, which are the main spaces of dam green infrastructure considering sustainability, view place was the highest at 4.43, the play space was 4.35 and public bridge was analyzed as 4.21. The t-test result for the satisfaction of each space was found to be p<.01, and the difference in values was analyzed to be significant. The difference from the current satisfaction with green infrastructure was also analyzed as p<.00, showing a statistically significant difference. Third, as a way to revitalize green infrastructure around the dam through the results of satisfaction analysis, it is necessary to identify needs for major visitors in their 40s and 50s and create a space considering them. It was proposed to derive facilities and programs that can be introduced to other regions through the analysis of green infrastructure status around dams in Chungbuk, Jeonju, and Ulsan, where there are relatively many dams. Furthermore, satisfaction analysis by space showed that green infrastructure around the dam could be activated in terms of sustainability when selecting packaging materials considering the structure and shape of the dam, arranging observation facilities considering lake prospects, and introducing amusement facilities using local environmental resources. This study differs from previous studies in that it presented space improvement measures in consideration of sustainability for green infrastructure around dams for non-urban areas, and space improvement can contribute to improving it connectivity in urban and non-urban areas, which can also contribute to improving the sustainability of green infrastructure in Korea.

본 연구는 다목적댐, 용수댐, 홍수조절지댐 등 39개 댐 주변 그린인프라에 대한 만족도를 분석하여 지속가능성 측면에서의 공간개선을 유도할 수 있도록 하였으며 연구 결과는 다음과 같다. 첫째, 현재 조성된 댐 그린인프라에 대한 리커트(Likert) 척도 5점 기준 만족도는 3.76으로 나타났고 응답자의 성별, 나이, 거주지, 댐 방문 횟수, 지속가능성 추구 필요성에 따라 차이가 있었으며 통계적으로 유의한 것으로 분석되었는데, 성별의 경우 p<.05, 나이, 거주지, 댐 방문횟수, 지속가능성 추구 필요성은 p<.01로 나타났다. 이러한 응답자 특성이 만족도에 미치는 영향을 확인하기 위하여 회귀분석을 실시한 결과, 댐 방문횟수와 지속가능성 추구 필요성만이 통계적으로 유의한 영향을 미치는 것으로 나타났고 이외의 특성 변수는 유의한 영향을 미치지 않는 것으로 분석되었다. 둘째, 지속가능성을 고려한 댐 그린인프라의 주요 공간인 공도교, 전망공간, 놀이공간의 구상 이미지에 대한 만족도에서는 전망공간이 4.43으로 가장 높았고, 놀이공간이 4.35, 공도교가 4.21로 분석되었다. 각 공간의 만족도에 대한 t-test 결과 p<.01로 나타나 값의 차이가 유의한 것으로 분석되었고 현재의 그린인프라에 대한 만족도와의 차이는 p=.00으로 분석되어 통계적으로 유의한 차이를 보였다. 셋째, 만족도 분석 결과를 통한 댐 주변 그린인프라 활성화 방안으로는 주요 방문객 대상을 40대~50대를 대상으로 니즈(needs) 파악 및 이를 고려한 공간 조성이 필요하며, 비교적 댐이 많이 분포하고 있는 충북, 전주, 울산 지역의 댐 주변 그린인프라 현황 분석을 통한 타 지역에 도입 가능한 시설, 프로그램 등을 도출하는 것을 제안하였다. 또한, 공간별 만족도 분석결과 댐의 구조와 형태를 고려한 포장 재료 선정, 호수의 전망을 고려한 전망시설 배치, 지역의 환경 자원을 활용한 놀이시설 등의 시설 도입 시 지속가능성 측면에서 댐 주변 그린인프라 활성화가 가능할 것이며, 공간별 만족도에 대한 t-test 결과를 활용하여 우선적으로 시행이 필요한 공간을 전망공간으로 제시하였다. 본 연구에서는 비도시지역에 위치한 댐 주변지역의 그린인프라를 대상으로 지속가능성 측면을 고려한 공간개선 방안을 제시하였다는 점에서 선행연구와 차별성을 가지며, 이에 대한 공간개선은 도시지역과 비도시지역의 그린인프라 연결성 향상에 기여 가능하며, 이는 우리나라 그린인프라의 지속가능성 향상에도 기여할 수 있을 것이다.
