Landscape design under the influence of digitalization is studied in the paper. The ultimate purpose of environmental design is to apply social, economic, artistic, technological, political and other comprehensive means to meet the needs of people's existence and development in the urban environment. The artistic image generation of forest landscape is in its various constituent elements and space with its own laws of formal beauty. The interplay of different elements as the interweaving and fusion of different elements constitute the garden environment, form and other different artistic The artistic image of the garden landscape space is more harmonious and unified, and in the human aesthetic interest in the world of human emotions. This paper gives the novel ideas for the digital analysis and provide the novel suggestions.

The numerical analysis software ABAQUS has been used to study the temperature field of an assembled steel-truss concrete hollow floor in this paper to simulate the assembled steel-truss concrete hollow floor under thermal coupling under the ISO-834 standard heating curve. The distribution principle of temperature field for different sections in the floor system has been obtained to provide a reference for the study of the mechanical properties of assembled steel-truss concrete hollow floor.

Against the background of the later epidemic era, this paper analyzes the current development situation of China's cold chain logistics market and the pain points of the food cold chain logistics information traceability system, and finds and summarizes the problems of the current China's food cold chain logistics traceability system. Based on the blockchain technology, the construction and research of the food cold chain logistics traceability system can be carried out, and the improvement of the global positioning system of cold chain logistics, intelligent temperature control and the construction of the Internet of Things can be achieved from the three aspects of the setting of participants, so as to better implement the rural cold chain logistics. The research shows that based on the "first kilometer" and "last kilometer" issues under the current rural cold chain logistics background, the combination of cold chain logistics and blockchain technology will bring about the deep integration of models and technologies. Finally, based on the current blockchain technology, the paper puts forward suggestions and management implications for the development of rural cold chain logistics.
