A system and method for constructing a suitable area for an ecological sponge city

Abstract

The invention discloses a system and a method for precisely identifying a target and calculating an effect in an ecological sponge type urban construction suitable area. The system comprises a spatialdata acquisition module, a suitable area spatial identification module, an index control and measure design module and a construction effect calculation module. The method is used for sponge city construction from city construction planning to engineering design whole process. Accurate identification of construction and reconstruction target suitable areas and suitable grade targets in urban heatisland control and urban landscaping processes can be realized, and the effects of flood disasters and high-temperature extreme climate events under different urban construction and reconstruction scenarios can be measured and calculated. The system comprises a novel sponge city and heat island control dual-target city planning and design framework, achieves refined remote sensing classificationand artificial intelligence detection algorithm aiming at precise identification of the ecological sponge city space suitability, and can effectively simulate the effects of city construction and reconstruction on rain flood and extreme high temperature events.

Description

technical field [0001] The invention relates to a system and method for accurate identification of targets in suitable areas for ecological sponge-type city construction and efficacy measurement, and belongs to the application fields of remote sensing and geographic information technology applied in urban planning and design and ecological environment protection industries, and focuses on the development of new urban areas and the development of old urban areas. During the reconstruction, the targets of suitable areas serving the comprehensive targets of urban stormwater management and urban heat island control are accurately identified, and the comprehensive effects of the above two targets in the city under different construction scenarios are calculated. The fields of geographic information and ecological environment protection have extensive and urgent application requirements. Background technique [0002] Since the 21st century, with China's rapid urbanization, urban f...

Problems solved by technology

There are also related patents on "a construction method and system for an ecological city" (public number CN107993173A, publication date May 4, 2018) and other related patents on the potential evaluation of ecological city construction, which are difficult to meet the practical application of sponge city construction planning and design need

Therefore, there are relatively few patents on the target identification of suitable areas for ecological sponge city construction and the layout of green infrastructure for the early planning and design of sponge city construction.
