[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0024] Embodiment 1

[0025] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of an embodiment of a method for generating an ecological region temperature field based on GIS according to the present invention. Figure 1 As shown, the method comprises the steps of:

[0026] S11: Get multiple temperatures at multiple observation points in an ecological region;

[0027] In step S11, a meteorological observation station is set up at each observation point, and the temperature at the observation point is monitored by the meteorological observation station.

[0028] Preferably, the number of the observation points is 3 to 15.

[0029] S12: Acquire GIS data corresponding to the ecological region, the GIS data including: a plurality of GIS grids and geographic information parameters corresponding to each GIS grid;

[0030] The geographic information parameter includes: height. It should be noted that the height is the altitude.

[0031] In step S12, the GIS spatial database is connected to obtain GIS data corresponding to the ecological region. The GIS data includes: multiple GIS grids for dividing the ecological region, and geographic information parameters corresponding to each GIS grid, where the geographic information parameters refer to the height.

[0032] S13: performing data fitting on the geographic information parameters corresponding to the multiple observation points and the temperature to obtain a temperature-geographic information parameter conversion formula for the corresponding relationship between the temperature and the geographic information parameters in the ecological area;

[0033] The temperature-parameter conversion relationship formula is: t=f1(h)*f2(h); wherein f1(h) is a step function and f2(h) is a normal distribution function.

[0034] Specifically, Among them, T1, T2, and T3 are temperature constants, and H1 and H2 are height constants.

[0035] Among them, σ is the variance, μ is the expectation, and 0<f2(h)<1.

[0036] S14: Based on the temperature-geographic information parameter conversion formula and the geographic information parameter corresponding to each GIS grid, the temperature corresponding to each GIS grid is calculated.

[0037] The height corresponding to each GIS grid in the ecological region is obtained, and the height is substituted into the formula of step S13 to calculate the temperature corresponding to each GIS grid, that is, the temperature field distribution of the ecological region.

[0038] Preferably, the same color scheme is used to display the temperature field corresponding to the ecological region. Figure 2 The steps shown include the following steps:

[0039] S141: Obtaining an RGB-temperature conversion formula for the corresponding relationship between RGB values ​​and temperature;

[0040] In step S141, the RGB-temperature conversion formula may be: R=f1(T), G=f2(T), B=f3(T), where R, G, and B are the values ​​corresponding to the three primary colors in the RGB value.

[0041] The RGB-temperature conversion formula can be generated by the following method: define the RGB value corresponding to the highest temperature and the RGB value corresponding to the lowest temperature in the ecological area, and derive the RGB-temperature conversion formula of the correspondence between the RGB value and the temperature based on the RGB value corresponding to the highest temperature and the RGB value corresponding to the lowest temperature.

[0042] S142: input the temperature of each GIS grid into the RGB-temperature conversion formula to obtain the RGB value of each GIS grid;

[0043] S143: Display the color of each GIS grid using its corresponding RGB value.

[0044] In this way, according to the color depth of each GIS grid, the temperature corresponding to the GIS grid can be known. Generally, in step S141, the area with high temperature is generally defined as dark color, and the area with low temperature is generally defined as light color. In this way, the user can know the temperature corresponding to each GIS grid from the color of each GIS grid, so that the temperature distribution of the entire ecological area can be clearly seen.

[0045] In this embodiment, by using temperature data and GIS data from meteorological monitoring stations based on small samples, the temperature distribution of the entire ecological area can be obtained. This method of monitoring temperature can achieve equivalent temperature monitoring under limited monitoring conditions, with low monitoring costs and the monitoring results are within the allowable error range.
