Example Embodiment

[0061] Example 1

[0062] This embodiment takes Chizhou City, Anhui Province as the background and combines figure 1 Using the method of the present invention, a low-impact development facility combination and layout plan are determined for a certain low-impact development catchment area A.

[0063] Step 1: Build a 0-1 planning model

[0064] In this embodiment, the catchment area A, with a total catchment area of ​​30.56 ha, is divided into 7 sub-catchment areas (S01-S07).

[0065] According to the guide and the zoning chart of total annual runoff control rate, the total annual runoff control rate of Chizhou is determined to be 80%. According to the characteristics of Chizhou city and catchment area, three types of low-impact development facilities are selected: biological retention facilities, permeable paving, Green roof.

[0066] Decompose the total annual runoff control rate from 80% to 7 subcatchments, and consider arranging these three low-impact development facilities in each p...

Abstract

The invention discloses a low influence developing facility combination and layout determination method of a sponge city, and belongs to the technical field of urban draining. The method is based on 0-1 planning model and scheme acquisition and cost-effectiveness analysis, and integrates annual flow amount control rate assessment and cost effect assessment. The method includes the steps of 1) 0-1 planning model, 2) generating a combination and layout schemes, 3) collecting schemes, 4)simulating the schemes and calculating indexes, 5) sorting the schemes, 6) analyzing cost effectiveness, and 7) determining a scheme, in which the schemes are ranked from highest to the lowest based on effect-to-cost ratio according to cost-effectiveness analysis, and a recommended low influence developing facility combination and layout scheme is determined according to the ranking result. The annual flow amount control rate and cost of low influence development scheme can be evaluated, and a low influence developing facility combination and layout can be determined. The method is used to assist planning and designing a low influence developing rainwater system of a sponge city.

Description

technical field [0001] The invention belongs to the technical field of urban drainage, and more specifically relates to a method for determining the combination and layout of low-impact development facilities in a sponge city. Background technique [0002] Under the background of global climate change and urbanization, urban waterlogging occurs frequently. One of the important components of the urban waterlogging prevention system is the low impact development (LID) stormwater system. The combination and layout of low-impact development facilities in the stormwater system of sponge city low-impact development are crucial to the performance of the entire system. Due to the wide variety of low-impact development facilities, their combination and layout is a difficult problem and a challenge. Therefore, optimization methods for the layout of low-impact development facilities have become a research hotspot for many researchers. [0003] For example, Xiao-Yue Zhen et al. used ...
