Problems solved by technology
Existing studies have found that the problem of urban light pollution has seriously affected astronomical observations, human physical and mental health, and the ecological balance of nature.
In the current night-time light environment observation technology, nighttime satellite maps are mainly used to observe urban sky glow, ground road lighting, and building outdoor lighting, etc., and there is a lack of relevant testing techniques such as the distribution of light pollution in the overall space

Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.
[0028] Work process 1: Description of the general monitoring method of the urban night sky layer, such as Figure 1~3 . Select the ground measuring point 18, use the instrument sky quality measuring instrument, make the device face the city zenith 1 vertically, get the reading perpendicular to the zenith area 9, take the center point from the ground measuring point 18 to the zenith area 9 as On the vertical axis, using a protractor, the angles are shifted downwards by 15°, 30°, and 45° on the same vertical plane, and the readings of measuring point 10 with a height circle of 75° and measuring point 11 with a height circle of 60° are respectively obtained; The above is taken as a set of vertical surface measurement results. Then take the surface of the ground measuring point 8 as the horizontal reference, ...

The invention provides a city night light pollution testing method, belonging to the light pollution measurement technology field. The city night light pollution testing method expands a study object of light pollution from sky light to a whole city circle and can observe a stereoscopic light pollution condition from three aspects which include a city ground surface layer, a city canopy layer and a city night sky layer. The city night light pollution testing method integrates light pollution with factors affecting light transmission in the city, performs quantitative testing on city light pollution distribution condition from an angle of multiple aspects, directly shows a city light pollution severity degree under different conditions, provides the basis to a city integral ecological illumination plane and has significance to the studies of an affect of the city light pollution on the city and a relation between city activities and light pollution.
Description
technical field [0001] The invention belongs to the technical field of light pollution measurement, belongs to the technical field of urban physical environment planning and design, and specifically relates to an observation method of urban nighttime light pollution and a brightness testing method. Background technique [0002] With the acceleration of urban modernization and rapid economic development, people's demand for night lighting has also increased, and the problem of light pollution has become increasingly prominent. Existing studies have found that the problem of urban light pollution has seriously affected astronomical observations, human physical and mental health, and the ecological balance of nature. In the current night-time light environment observation technology, nighttime satellite maps are mainly used to observe urban sky glow, ground road lighting, and building outdoor lighting, etc., and there is a lack of related testing techniques such as the distribu...
