The design concept of Qinghe Park takes folk customs as its connotation, natural landscape as its support and ecological protection as its foundation, and it has assumed three main roles of flood detention, hydrophilicity and leisure in Yueqing urban planning. It includes four characteristic elements of Yueqing "mountain, river, sea and city" and five functional carriers of life service, high-speed dense forest, island tour, wetland flood detention and popular science creativity. The islands dotted in the lake in the park are connected in series by various bridges, showing an extraordinary scene of flying rainbow surrounded by waves and meandering water.
