Resource-based cities generally have "high energy consumption, high carbon emissions, and high pollution". Exploring low-carbon planning of resource-based cities means great significance for promoting the low-carbon transformation and development of resource-based cities and achieving "carbon peak" and "carbon neutrality". Based on the two levels of city region and central city, the paper proposes a low-carbon planning method for resource-based cities from four aspects: industrial transformation, land use, road transportation and ecological environment. At the city region level, it is necessary to reasonably determine urban industrial structure and industrial development scale, and meanwhile, optimize the industrial layout by reasonably planning production, living and ecological space and formulating practical space control measures; coordinating the connection between external traffic and traffic system within the city; constructing a carbon sink network composed of green patches-ecological corridors-peripheral matrix. At the central city level, it is necessary to analyze gradient attributes of carbon emissions from different land types, rationally arrange various types of construction land; optimize the layout of urban residence and employment space; increase systematicness of road planning in central urban areas; give full play to the carbon sink role of ecological corridors. Finally, an empirical study is carried out with the case of Xingtai City. The research can provide theoretical basis and path reference for reducing carbon emissions of resource-based cities through spatial planning.

In the UK, one of the worst affected countries by the SARS-CoV-2 global pandemic, the UK government has released a comprehensive vaccination plan for SARS-CoV-2 and will set up more vaccination sites in the coming months to expand the service to more people. We built an extended Bayesian hierarchical prediction model to predict the number of cases and breeding situation after vaccination in the nine districts of England. Based on the population of each region, the number of deaths and the IFR (the infection mortality ratio) for each region were predicted. We found that EAST, NORTHWEST and SOUTHEAST had the largest IFR, and the corresponding death numbers were 29,079, 28,734 and 25,201, respectively. Reproduction number ( ) is expected to drop below 1 in all regions on January 7, January 12, January 16, January 13, January 10, January 17, January 10, January 18 and January 14, respectively. Major vaccine interventions have been effective in reducing transmission in the nine areas of England given the mortality rate of the infected people and epidemiological characteristics of SARS-CoV-2. We also found that vaccination among people aged 70 to 80 had made a significant contribution to reducing transmission of the virus. The model can be extended to forecast the effects of certain interventions in public health emergencies, the effect of preventing the spread of disease, and the effect of different interventions in different age groups to find the best way to control the spread of disease. It can also be extended to drug and non-drug interventions to find the best combination of solutions.

The smoothness of a city's traffic is one of the signs that measure the development of a city. With the advent of the era of artificial intelligence and big data, the previously bloated and blocked motor vehicle transportation system is increasingly unable to adapt to this fast-paced society. The use of artificial intelligence technology to build a brand-new intelligent transportation platform is imminent, and reasonable planning of the risks in the construction of the transportation platform can effectively increase the transmission rate and reduce the frequency of accidents. The purpose of this paper is to study the risk management in the construction of intelligent transportation platform based on artificial intelligence. This article first summarizes the basic theory of artificial intelligence, and then extends the core technology of artificial intelligence. And combined with the current situation of my country's contemporary intelligent transportation, analysis of the existing problems and shortcomings, on this basis, combined with artificial intelligence technology to research and analyze the risk management in the construction of intelligent transportation platform. This research systematically expounds the risk construction principles, model construction and risk response measures of the intelligent transportation platform.
