Abstract

The invention provides an urban heat island effect space variation detection method and system. The urban heat island effect space variation detection method comprises the steps: constructing an urban remote sensing data image database for the processed urban remote sensing images; according to the image database, acquiring a plurality of thematic images of a target city; and according to the thematic images, detecting the space-time distribution information of urban heat islands, and analyzing the urban heat islands; according to the urban heat islands, offering a proposal for urban landscape. Therefore, the urban heat island effect space variation detection method and system can overcome the spatial overlay algorithm problem between the heat island effect spatial distribution and other feature layers of the city, and can improve the accuracy for urban heat island effect space variation detection.

Description

technical field [0001] The invention relates to the technical field of urban management, in particular to a method and system for detecting spatial changes of urban heat island effects. Background technique [0002] With the rapid advancement of my country's urbanization process, the continuous expansion of urban population and land use has also led to the contradiction between the infinitely growing urban population and the limited environment and resource capacity. The city has been overwhelmed, and urban diseases have also emerged. . The impact of urbanization (land use (building, road construction, etc.) and man-made heat emissions, etc.) is often mainly realized through the enhancement of the urban heat island effect. Previous urban heat island studies mainly used the method of combining representative route observations and selected point observations. This method cannot fully and synchronously reflect the thermal radiation conditions on the ground. Therefore, with th...
