Environmental regulation of PM2.5 in urban green vegetation and the influence of green technology progress based on remote sensing image

Abstract

In the face of increasingly serious environmental problems, Chinese governments at all levels have issued a series of regulatory measures for energy conservation and emission reduction. The rational use of science and technology can not only improve environmental quality but also promote rapid economic development. In order to encourage and guide the development of green technology and drive the collaborative progress of preventive technology and processing technology, it is necessary to develop the green technology progress-oriented function of environmental regulation and explore its transmission mechanism. This paper analyzes the relationship between environmental regulation policy and green technology progress. The results show that environmental regulation policy is an effective way to promote the progress of green technology.; The regulation policy combination of environmental tax and environmental subsidy can effectively improve social welfare, which is embodied in the increase of output, the reduction of production cost, and the reduction of pollution caused by the coordinated progress of pollution prevention technology and pollution treatment technology. Through the means of spatial planning, we can provide the construction ideas with urban characteristics for the ecological city represented by vegetation coverage. We can improve the urban greening by inserting green in the cracks; we can also build various types of large-scale urban green belts by increasing urban farmland, so as to improve the construction of urban ecosystem.
