Abstract

It is suggested investigating method about the existing state of demand in this study. The total demand of 357 water amenity zones in 2014 is estimated based on the growth curve models. The effects of population density and distances between water amenity zones and metropolises populated over 1 million are investigated on each river system. The suitability like RMSE and MAPE of logistic and gompertz models are considered to select more suitable model for each water amenity zone. Demand for water amenity zones in 2014 is seemed to be rather high at Han Gang river system and Chungcheongbukdo after analyzing. The influence of population density is rarely effective except Geum Gang river system. The influence of metropolis on the demand for water amenity zones is higher at Geum Gang river system than others.

본 연구에서는 한강, 낙동강, 금강, 영산강, 섬진강 등을 중심으로 신규 조성된 친수지구에 대한 이용 현황 조사 방안을 제안하고, 조사 결과를 토대로 성장 곡선 모형을 이용하여 총 357개 지구에 대한 2014년 이용수요를 예측하였다. 또한 친수지구가 위치한 지방자치체의 인구밀도와 수계별로 위치한 인구 100만 이상 도시와 친수지구 사이의 거리에 의한 영향을 검토하였다. 각 친수지구별로 로지스틱 모형과 곰페르츠 모형으로 추정한 결과를 RMSE와 MAPE 적합도를 이용하여 선택하였으며, 분석 결과 2014년 친수지구 이용수요는 한강 수계와 충청북도에서 상대적으로 활성화 된 것으로 나타났다. 인구밀도의 영향은 금강 수계를 제외하고는 비교적 미미한 것으로 보이며, 친수지구 이용에 대해서는 대도시 영향이 나타나긴 하나, 마찬가지로 다른 수계에 비해 금강 수계에서 대도시 영향이 큰 것으로 나타났다.
