The Reconstruction of Guilin's Urban Ecological Landscape Based on the Concept of Sponge City

Abstract

Guilin is an international tourist city famous for its landscape, but the prominent contradiction in water usage becomes one of the key factors that influences and restricts the construction and development of the city. As an effective measure to relieve the contradiction of urban water usage, the concept of “sponge city” has achieved success in many places. Thus, building Guilin urban ecological landscape on the basis of the concept of “sponge city” is of great significance for the effective relief of the contradiction in water usage and the realization of sustainable development. Academic studies point out that for the purpose of the construction of sponge city, the construction of Guilin's urban ecological landscape first need to adopt sponge strategies in urban residential areas, transform or build a virtuous circulating green space system to collect, purify and store rainwater in an effective way. Secondly, build rainwater collection, purification, storage facilities or systems extensively and replenish urban ecological water reserve in the grey system of the city, according to the concept of “sponge”. Thirdly, considering the large area of Guilin city parks, build rainwater self-use rain systems extensively in city parks based on the concept of sponge and substantially reduce external ecological water reserve. Fourthly, reinforce training and learning related to the concept of “sponge city” and the implementation of “sponge city” policies.
