The method provides theoretical basis and scientific reference value for reasonable layoutand configuration of urban land resources.

Description

technical field [0001] The invention relates to the field of earth science and technology, in particular to a method for simulating urban heat island effect scenarios coupled with land use planning. Background technique [0002] Since the middle of the 20th century, urbanization has become one of the most important human activities. The influx of extensive rural population into cities not only changes the land cover / use types of the underlying surfaces of cities, but also the process of transforming urban green spaces into impermeable surfaces often leads to an ecological imbalance between urban and rural areas, while disturbing atmospheric circulation and air , water balance, and thus have a great impact on the urban ecological environment. Among them, the urban heat island effect (Urban Heat Island, UHI) is a typical urban climate phenomenon accompanied by the development of urbanization, which is reflected in the fact that the temperature in the central city is much high...

Problems solved by technology

The research on the coupling relationship between the urban heat island effect and land use planning is mainly manifested in the qualitative analysis of the heat island effect by using different technical methods and means, but there is a lack of more quantitative models to better characterize the numerical value between the two. relationship, and the lack of scenario simulation analysis of the heat island effect through the simulation results of land use under different planning scenarios, so new methods and models need to be introduced
