Selection and Application of Garden Plants in the Construction of Sponge City in Northwest China

ABSTRACT Li, R. and Zhang, C., 2020. Selection and application of garden plants in the construction of sponge city in Northwest China. In: Yang, Y.; Mi, C.; Zhao, L., and Lam, S. (eds.), Global Topics and New Trends in Coastal Research: Port, Coastal and Ocean Engineering. Journal of Coastal Research, Special Issue No. 103, pp. 1139–1143. Coconut Creek (Florida), ISSN 0749-0208. Since the development of sponge city construction in my country, most of the research on sponge city construction has focused on the engineering level. The research on the selection and application of plants is relatively lagging, making it impossible to reasonably choose plants during the construction of sponge cities. The lack of “localization” of the design and the lack of systematic and targeted consideration and design of the plant landscape configuration have restricted the construction and development of the sponge city to some extent. The purpose of this article is to solve the problem of the selection and application of garden plants in the construction of sponge cities in the northwestern region. Through the literature review method, field survey method, and case comparison analysis method, the roof garden, residential area green space, road green space, and landscape in the sponge city in northwestern China Selection and arrangement of plants in green space and park green space. Finally, combined with the problem analysis, the principles of sponge city plant selection and allocation were put forward. At the same time, the sponge city plants that can be applied to the northwestern region were summarized based on the survey results and related literature reading. The research results show that the satisfaction of the open layout is 81.38%, and the satisfaction of the enclosed layout is 79.30%. The open layout is more popular in use. The selection and application of garden plants in Northwest China based on the construction function of sponge cities proposed in this paper has positive significance for sustainable urban development.
