Urban agglomeration ground surface heat island intensity evaluation method and system, medium and terminal equipment

Abstract

The invention relates to an urban agglomeration ground surface heat island intensity evaluation method. The method comprises the steps of acquiring ground surface temperature data of a target urban agglomeration in a target time period, and evaluating the heat island intensity of the target urban agglomeration according to the ground surface temperature data; screening out potential driving factors influencing the urban agglomeration heat islands according to the urban agglomeration data of the target urban agglomeration in the target time period, and creating a cause data set of the urban agglomeration heat islands according to the potential driving factors; based on the evaluation result of the intensity of the urban agglomeration heat islands and the cause data set, constructing a cause determination model of the urban agglomeration heat islands by adopting an enhanced regression tree method; and operating the urban agglomeration heat island cause determination model to obtain a cause diagnosis result of the target urban agglomeration heat island, and determining an urban agglomeration heat island cause mechanism according to the cause diagnosis result. Compared with the prior art, the method has the advantages that the urban agglomeration is regarded as an integral area to evaluate the heat island intensity and analyze the relative importance and marginal effect of the cause of the heat island intensity, and a scientific basis is provided for relieving the regional heat island and constructing the livable urban agglomeration.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, system, storage medium and terminal equipment for evaluating the intensity of surface heat islands in urban agglomerations. Background technique [0002] With the rapid development of society, the population has also increased rapidly, thus realizing rapid urbanization. However, rapid urbanization and population growth have also caused a series of environmental problems, among which the urban heat island effect is one of the most significant human impacts on the earth's environment. Urban heat islands generally refer to the human-induced increase in temperatures in urban areas compared to surrounding suburban or rural areas. More and more studies have shown that urban heat islands have a great impact on vegetation growth, water and air quality, urban energy consumption, human thermal comfort and health risks, morbidity and mortality. Therefore, there is an...

Problems solved by technology

[0004] However, since the reduction or even disappearance of the distance between cities in the urban agglomeration area will significantly change the regional thermal environment, the surface heat island intensity of the urban agglomeration is no longer suitable for evaluation from the perspective of the current mainstream single city
