Research On Landscape Design Of City Roadside Green Space Under The Perspective Of Sponge Urban System

In recent years,the construction of "the sponge city" has received great attention in our country.The landscape design of various types of green spaces has also begun to take into account the function of sponges.The greenery on the streetside is a category that covers a wide area under "the green space of the park".In the sense of the construction level of the sponge city,a small amount of green space function can also achieve considerable results,and at the same time it can stimulate the vitality of the city.Through the interpretation of the connotation category of urban sponge and sponge city,and the analysis of the characteristics of street greenland,this article proposes the necessity and feasibility of combining street greenland and sponge city concept.The analysis of the morphological characteristics of the sponge facilities combined with the classification line and problems of sponge facilities,proposed a new classification.The new classification divided the facility into 3 categories,according to the form of points,lines,and face.The "points in the sponge" were inferred from "points in morphology" and“points in the landscape," similarly,and the "line in the sponge" was inferred from“line in morphology" and“line in the landscape”,and the "face in sponge" was inferred from "face in morphology" and "face in the landscape”.Then the various facilities are divided into categories according to the characteristics.This is the landscape composition material system.Then,how do the rainwater function and the landscape and recreation function be allocated in time,share in space,how to use the rainwater function to enrich the information contained in the landscape,and how to use the landscape aesthetics to improve the form of the sponge facilities,From the point of view of how the combination of rainwater functions and participation behaviors and multi-functional thinking is the starting point,five landscape enhancement methods are sorted out:first,pay attention to the beauty of the facilities themselves and eliminate stereotypes;second,landscape design for different water volumes should be done.Rain and no rain can be the scene,more water and less water can be visited,and third,a rich layer of design can improve the landscape quality of the sponge landscape;Fourth,we should strengthen the design of the facility edge space;Fifth,should pay attention to tourists Participation design.Finally,take the greenery near the three blocks in the Shaerqin Development Zone in Hohhot as an example,and make a sponge-like street green space landscape design.Applying the above-mentioned theoretical research results to practice,it was confirmed that the sponge landscape can guarantee high-quality landscape effects while ensuring the function of rainwater flood,and is not the same as the "puddle".
