Sponge city planning and design system

Abstract

The invention relates to a sponge city planning and design system. The system comprises a sponge facility determination module which is used for selecting a sponge facility suitable for a project from selectable facilities according to a design rule; the sponge simulation model is used for obtaining a sponge model simulation result through system calculation, site calculation and LID facility calculation based on the selected sponge facility; the sponge optimization evaluation module is used for performing optimization analysis on the sponge model based on a discrete search algorithm by taking a combination of an optimization target and a constraint condition as an optimization condition to obtain an optimal design scheme set; the optimization targets comprise the minimum construction investment, the maximum runoff control target, the maximum surface runoff pollution control target, the minimum pollutant load, the minimum peak flood flow and the minimum operation maintenance cost; the constraint conditions comprise an annual runoff total amount control rate, a runoff pollution control rate and a flood peak flow. According to the method, the design efficiency and scientificity of the LID facilities in sponge city construction are improved.

Description

Technical field [0001] The present invention belongs to the field of sponge urban planning, in particular, involving a sponge city planning and design system. Background technique [0002] The construction of sponge city mainly promotes simulation of natural conditions. By using some micro-decentralized ecostructive techniques to make regional development of hydrological characteristics and basically consistent with development, it is guaranteed to minimize land development on the effects of land development on the ecological environment. Through low impact development, the ecological objectives can be achieved: protecting water quality, reducing runoff flow, extending runoff set, cutting flooding, supplementing groundwater, reducing land erosion, etc. Through low impact development, comprehensive utilization is developed, and the damage due to land development activities on ecosystems will restore them to the level of development before the development of construction, and to ac...

Problems solved by technology

[0003] The sponge model in the prior art is mainly (1) mostly a single model, which is not combined with the entire system, and lacks practicability; (2) mostly black box models, lacking the necessary theoretical support; (3) directly using foreign computing engines and simulation algorithms, lack of innovation

(4) Calibration and verification of laboratory research results are mostly used, lacking engineering
