RS-based Analysis of the Impact of Land Use Change on Hotspot Effect and Carbon Distribution in Shanghai (2010- 2020)

To increase the productivity of cities and the quality of life of human beings other than the environment, urban land is constantly expanding and compressing and destroying the original ecological environment. This paper takes Shanghai as an example and analyses the influence of urban land use changes on the trend of heat island effect and carbon distribution based on remote sensing data. This paper concludes that the land use of building land is still increasing, but the rate of increase has been reduced in recent years, and the heat island effect has also been significantly reduced after 2015. Although the distribution has not changed much, it has also reduced the carbon source area and total carbon emissions after 15 years. The Shanghai municipal government has paid more attention to environmental protection in recent years, such as implementing a policy of strictly controlling the size of construction land to reduce urban sprawl and protect ecological land. The analyses in this paper can help to predict future ecological and climate change in Shanghai, and can help to improve the land use structure and promote sustainable development in the city in the future.
