Problems solved by technology

In order to achieve a balance between high temperature and thermal comfort, the city consumes a lot of energy for cooling, but at the same time emits a large amount of man-made heat and air pollutants, causing a vicious circle, increasing human discomfort, and seriously violating green and sustainable development. concept of development

Embodiment

[0023] refer to figure 1 , this Example 1 provides a recommendation to formulate mitigation measures according to the heat island intensity level, including steps:

[0024] S1: Collect the urban element data and Landsat8 remote sensing image data needed to establish the regression relationship;

[0025] S2: Use the atmospheric correction method to perform temperature inversion on remote sensing images to obtain urban surface temperature data;

[0026] S3: Use the ArcGIS regional statistical tool to count the surface temperature of each analysis unit and the factors affecting the heat island effect;

[0027] S4: Test the significance and multicollinearity of each influencing factor to ensure that the influencing factors participating in the modeling are significant and there is no multicollinearity;

[0028] S5: Use Moran’s I to judge the spatial autocorrelation of surface temperature; if there is spatial autocorrelation, proceed to the following steps, if not, terminate the ...

Abstract

The invention belongs to the field of heat island effect and urban planning management, and relates to a recommendation method for formulating retarding measures according to heat island intensity grades. The data mainly comprise air temperature data or surface temperature data and influence factor data. According to the method, a spatial quantile regression model considering spatial dependency and heterogeneity is adopted, the difference influence of urban elements on the heat island effect is mined, and differential retarding measures according to different heat island intensities are provided according to a regression result. Therefore, targeted and efficient slowing-down measures are selected in different regions according to the intensity of the heat islands in the regions instead of adopting a unified policy with other regions. By adopting the method, unnecessary waste of manpower, material resources and financial resources is reduced, resource elements are scientifically configured, and the utilization efficiency of resources is improved.

Description

technical field [0001] The invention belongs to the field of heat island effect and urban planning management, and relates to a recommended method for formulating mitigation measures according to heat island intensity levels. Background technique [0002] While people are enjoying the benefits brought by urbanization, the risks of urbanization are also quietly coming. The urban heat island effect, that is, the phenomenon that the urban temperature or surface temperature in the urban area is significantly higher than that in the suburbs is a kind of urbanization risk. In recent years, the summer temperature in cities has remained stable, and the number of "stove" cities is increasing. While changing the local climate, the heat island effect seriously threatens the lives of urban residents. In order to achieve a balance between high temperature and thermal comfort, the city consumes a lot of energy for cooling, but at the same time emits a large amount of man-made heat and a...
