However, flood control and drainage are the only focuses, and the rest functions of water course are slighted. Besides, cross-section biodiversity is falling and wetland self-cleaning capacity is impairing, resulting from river limitation on riverbed, making a straight river bend and revetment. So, water course has to be managed from ecology, economy, culture and social effect, to re- store natural river function and meet human demands. And to return to nature and people first would be the general principles.展开更多

In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.展开更多

Nowadays, "Sponge City" has become the focus of the planning and design of urban residential areas. Through the investigation and evaluation of several residential sponge projects, it is found that the landscape effect of sponge facilities cant meet the aesthetic needs of residents, besides its own function of regulating and storing rainwater. Therefore, improving the landscape effect of sponge cities in residential areas is the main direction of later sponge city construction. This paper summarizes the obstacles encountered in the application of sponge city concept in civil architecture design, and finally puts forward relevant measures, hoping to provide valuable reference for relevant designers.展开更多

Combining with the concept of sponge city design, urban road green space landscape also has the functions of water storage, water saving, water purification and drainage. The green plants themselves need water resources for irrigation. Through the construction of sponge citys technical facilities, more abundant water supply can be provided for the green landscape plants. At the same time, it can absorb and store the accumulated water on the city roads, thus improving the effect of water resources utilization. In the landscape design of urban road greenbelt, the effect of water recycling can be improved through the design of sinking greenbelt and the design of overflow rain gate trash basket. Based on this, the article discusses the green street landscape design based on the background of sponge city.展开更多

Especially in the rainy season in July and August, the flooding problem in the city has been highlighted, which has brought potential safety hazards, not only threatening the safety of residents' lives, but also damaging the ranks of roads and bridges and reducing the service life of roads and bridges. In order to adapt to the construction concept of "Sponge City" and improve the design and construction level of local roads and bridges, relevant design knowledge must be used in the design and research of urban roads and bridges. The roads and bridges in the city have a lot of urban space. By doing a good job in the construction and design of roads and bridges, urban environmental problems can be effectively improved. In order to carry out the construction and design of roads and bridges, the concept of sponge city can be used to improve the urban environment and meet the need of optimal allocation of water resources. Therefore, in order to meet the needs of urban ecosystem construction, the systematic design of roads and bridges should be strengthened.展开更多

During the planning, design and construction period, all aspects should be considered as a whole, and the water resource utilization rate of roof rainwater and floor rainwater should be considered comprehensively to effectively reduce rainwater runoff, municipal rainwater drainage system, urban flood control pressure and waterlogging risk. The concept of "Sponge City" is applied to the design of building water supply and drainage. In the process of urban development and construction, public buildings and residential buildings are "constructed with low impact development rainwater system". Combining with the improvement of urban flood control, drainage and drainage systems, the goal of building an economical and environment-friendly city is achieved, the distance between the masses and nature is narrowed, and the stable development trend of the city is ensured. In this regard, the article takes the concept of "Sponge City" as an example, and elaborates the key points of its application in building water supply and drainage design, hoping to provide some reference.展开更多

Based on this, the article discusses the green street landscape design based on the background of sponge city.
文摘Sponge city refers to a new urban construction concept used to solve urban flood disasters and water ecological problems.It is important for the construction of ecological civilization.It plays an important role in the green development and livability of the city.In the construction of a sponge city,it is necessary to make special urban planning and improve the top-level design.In recent years,China has developed a number of sponge city pilot projects.The numerous experiments act as important references for the urban construction in China.This paper mainly analyzes the requirements for the construction of sponge city and discusses several problems as well as solutions in the construction.
文摘With the acceleration of China's urbanization process, rational planning of urban roads and bridges is especially important for normal production and life. Especially in the rainy season in July and August, the flooding problem in the city has been highlighted, which has brought potential safety hazards, not only threatening the safety of residents' lives, but also damaging the ranks of roads and bridges and reducing the service life of roads and bridges. In order to adapt to the construction concept of "Sponge City" and improve the design and construction level of local roads and bridges, relevant design knowledge must be used in the design and research of urban roads and bridges. The roads and bridges in the city have a lot of urban space. By doing a good job in the construction and design of roads and bridges, urban environmental problems can be effectively improved. In order to carry out the construction and design of roads and bridges, the concept of sponge city can be used to improve the urban environment and meet the need of optimal allocation of water resources. Therefore, in order to meet the needs of urban ecosystem construction, the systematic design of roads and bridges should be strengthened.
文摘The core concept of "sponge city" is introduced around the urban development and construction projects. During the planning, design and construction period, all aspects should be considered as a whole, and the water resource utilization rate of roof rainwater and floor rainwater should be considered comprehensively to effectively reduce rainwater runoff, municipal rainwater drainage system, urban flood control pressure and waterlogging risk. The concept of "Sponge City" is applied to the design of building water supply and drainage. In the process of urban development and construction, public buildings and residential buildings are "constructed with low impact development rainwater system". Combining with the improvement of urban flood control, drainage and drainage systems, the goal of building an economical and environment-friendly city is achieved, the distance between the masses and nature is narrowed, and the stable development trend of the city is ensured. In this regard, the article takes the concept of "Sponge City" as an example, and elaborates the key points of its application in building water supply and drainage design, hoping to provide some reference.
