Low-impact development simulation method and system and related device

Abstract

The invention provides a low-impact development simulation method. The low-impact development simulation method comprises the steps: acquiring geographical condition information and preset space planning requirements of all target land parcels; determining the waterlogging risk grade, the water environment pollution grade and the sponge measure arrangement potential grade of each target land parcel according to the geographical condition information and the space planning requirements; based on the waterlogging risk level, the water environment pollution level and the sponge measure layout potential level, determining a low-impact layout priority level of each target land parcel by utilizing a fuzzy comprehensive evaluation method; and optimizing and adjusting a plurality of targets of sponge city construction by utilizing a genetic algorithm according to the low-impact layout priority. According to the low-impact development simulation method, geographical condition information and preset space planning requirements of each target land parcel are comprehensively considered, and the rationality and effectiveness of sponge city construction can be improved. The invention further provides a low-impact development simulation system and device and a computer readable storage medium, which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of low-impact development simulation, in particular to a low-impact development simulation method, system, device, and computer-readable storage medium. Background technique [0002] Urban waterlogging is one of the major problems faced by many countries in their modernization drive. In recent years, with the dual effects of climate change and urbanization, the problems of waterlogging and water pollution caused by heavy rain have become increasingly serious. In response to the above problems, my country has gradually promoted and improved the construction of sponge cities. The stormwater management strategy represented by low-impact development (LID) is one of the major approaches to the construction of sponge cities. Through decentralized and small-scale source control mechanisms and design techniques, the management and regulation of stormwater runoff is realized. Between 2015 and 2016, my country succe...

AI Technical Summary

Problems solved by technology

The traditional low-impact development simulation method lacks index decomposition, layout and optimization research on low-impact layout, so it lacks top-down coordinated analysis, which easily leads to blind planning and subjective layout of sponge measures in the plot, resulting in repeated construction, Fragmentation, inefficiency and extensive problems make it impossible to achieve optimal allocation of resources

In addition, traditional low-impact development simulation methods seldom consider multiple influencing factors comprehensively, resulting in poor rationality for the construction of sponge cities
