Problems solved by technology

However, because the thermal properties of the land surface are closely related to many biophysical properties, it is not sufficient to study only the influence of a single surface biophysical parameter on the surface temperature.
In previous studies, there were cases in which four biophysical parameters were used to co

Embodiment Construction

[0083] The technical solutions of the present description will be further described below with reference to the accompanying drawings and embodiments.

[0084] A method of constructing a remote sensing integrated ecological model RSIEI for evaluating the differentiation effect of surface thermal environment in intensive mining development areas. First, the four ecological parameters selected are inverted by remote sensing technology, and the inversion results of the four ecological parameters are standardized to make the inversion results of the four ecological parameters standardized. Their respective value ranges are fixed in the range of [0, 1]. Then, the inversion results of the four ecological parameters are combined with bands, and then the principal component analysis is performed using the results of the combination of bands, and the first principal component is saved. In order to make the large value represent the result of good ecological environment quality, the fir...

Abstract

The invention relates to a construction method and application of a remote sensing comprehensive ecological model RSIEI for evaluating a ground surface thermal environment differentiation effect of amining development dense area. The construction method comprises the following steps: inverting the surface temperature of a research area by using a radiation conduction equation method; representingthe earth surface vegetation biomass by using the photosynthetic vegetation coverage parameter and the non-photosynthetic vegetation coverage parameter; characterizing the soil moisture content by using the soil humidity index parameters; representing the bare soil and building density by using bare soil and building index parameters; and integrating the four basic ecological parameters based ona principal component analysis method to construct RSIEI. The application comprises the step of quantitatively analyzing the contribution of four ecological parameters to the ground surface thermal environment differentiation effect of the mining industry development dense region by means of a statistical method. The method is suitable for evaluating the thermal environment differentiation effectof mining development dense cities, and evaluating the surface thermal environment differentiation effect of small-scale mining development dense villages and towns with administrative boundaries as boundaries is also feasible.

Description

technical field [0001] The invention relates to an ecological evaluation model based on remote sensing technology, in particular to a construction method and application of a remote sensing comprehensive ecological model RSIEI for evaluating the differential effect of surface thermal environment in intensive mining development areas. Background technique [0002] Rapid industrialization and urbanization have become a major phenomenon worldwide in recent decades, and although there are few studies on industrial land as an independent land form measuring heat island effects, its overall contribution to urban heat island values ​​is relatively low. It is limited, but industrial land is often the accumulation area of ​​the highest surface temperature, and the thermal areas within the city are basically concentrated in industrial areas. [0003] Cities emerging from energy are located in a large number of mining areas, industrial parks and other production facilities, which not o...
