1. scope of application

Environmental monitoring, urban planning, spatial remote sensing, urban ecology

2. Brief description of technology

This technology proposes a set of integrated technologies for three-dimensional monitoring and regulation of urban light pollution. It uses domestic high-resolution luminous remote sensing satellite data and ground urban light pollution station monitoring information, and uses spatio-temporal correlation method to build an urban light pollution coupling model. It has been successfully carried out in many cities in China and Israel. Quantitative simulation research on urban light pollution has been carried out to achieve a typical urban light pollution mapping resolution of better than 100m, the three-dimensional monitoring frequency is every year, and the accuracy of urban light pollution sources exceeds 95%. The project team's research and application of monitoring methods in the past ten years and the collaborative application technology of heaven and earth have achieved real-time and on-site monitoring and regulation of urban light pollution.

3. technical information

The monitoring is divided into three layers: urban night sky layer, urban canopy layer, and urban surface layer; multiple physical quantity monitoring indicators: brightness, illumination, color temperature, spectrum, radiation, etc.

4. comprehensive benefits

1. The benefits of the Belt and Road Initiative to control light pollution have become an academic issue involving the global environment that has attracted special attention from the international academic community in recent years. It is also an unshirkable responsibility and obligation of mankind and the global ecology. Urban expansion driven by economic development has brought serious urban light pollution, causing energy waste, abnormal work and rest of animals and plants, and increased cancer incidence. The scattered light formed will also have an impact on astronomical observations. Therefore, urban light pollution has become A common environmental problem faced by the development of "Belt and Road" cities. 2. The need to protect the global ecology currently does not have quantitative standards and guidelines in this regard in the world. Therefore, preventing and controlling light pollution and protecting the ecosystem is an urgent issue to be solved. Through the application of this technology, it can be carried out based on the geographical information system and the light environment, so that it can be carried out. The distribution status of light pollution in different regions and the scope of affected areas. 3. The need to promote the scientific and sustainable development of urban night lighting Scientific and sustainable night lighting requires that the impact of the artificial light environment on the surrounding physical environment should be minimized. Through year-round and all-weather regulation of this technology, various cities can be monitored in real time. Regional light pollution issues and early warning analysis.
