Construction and Regulation of a Novel Architectural Waterscape Based on Submerged Plants

Architectural waterscapes play a crucial role in enhancing the aesthetics and ecological value of the environment. However, water quality maintenance has been a significant challenge, leading to many of them prolonged closure. To address these issues, this study proposed constructing grass-type clear-water architectural waterscapes using submerged plants and investigated key factors involved in their construction. The study included experimentation with two ecological filtration systems, a shading system and a circulating filtration system. The feasibility of this approach was verified by an approximately four-month water quality monitoring process. Experimental results highlighted the significant role of light conditions and water transparency in establishing a grass-type clear-water architectural waterscape. Water quality monitoring outcomes demonstrated that grass-type clear-water architectural waterscapes were practical, generally meeting Class III of environmental quality standards for surface water in China. Therefore, grass-type clear-water architectural waterscapes are a promising alternative with good performance and minimal water resource consumption.
