ABSTRACT
The sudden outbreak of COVID-19 has not only affected people's normal life, but also brought certain impact on logistics. People's demand for agricultural products suddenly increased in a short time, and agricultural products logistics didn't have time to respond. Many new problems have been exposed, because there are many intermediate links in agricultural products logistics, so on the basis of higher logistics cost, it also increases the problem that logistics cannot guarantee timely supply. In addition, the price of agricultural products is low, and the cost of advanced technology is high, so it is impossible to use modern technology to trace the source of agricultural products. During the epidemic period, because the severity of the epidemic varies from place to place, it is particularly important to trace the source of products;at the same time, due to the sudden outbreak of the epidemic, it also brought challenges to emergency logistics, and the response of emergency logistics in various places was slow. However, the epidemic has brought difficulties to logistics and also created opportunities for the development of smart logistics. In order to avoid human contact, information registration systems have been adopted in various places, and unmanned driving, automatic warehousing, automatic distribution and logistics robots have been put into use, which has promoted the sharing of information by smart logistics using the Internet and the intelligentization of logistics operation process. © 2021 IEEE
