曲阜师范大学硕士论文 The research of safety tracing system about agricultural cold-chain logistics Abstract The safety consciousness in agricultural logistics has increased and the related national policies have also come out. In these situations more and more people pay height attention to the cold-chain logistics. Cold -chain logistics is composed by multiple segments, from food raw materials cultivation and procurement, processing, circulation and distribution, to retail and consumption; it is a complicated system engineering to ensure that each link in low temperature, quality and safety problems of cold chain logistics is the core. Cold chain of food not only for preservation, but also special attention to the security aspect, once appear quality security problem, it will endanger peoples health, Due to its particularity, the demand of each link in cold fresh food is very high. China is at this period which the risk of the food safety and the contradiction is highlighted at present. The special rectification of the food safety is a quite arduous task. Contrast to the past, food security situation of China has been significantly improved, but the situation is still not optimistic. With the frequently emerge of food safety accident; it is imminently to Promote the construction of traceability systems in the national wide. We analysis the problem from the current state of agriculture development ,based on modern network information systems, and constructs the cold chain logistics tracing system that covering the whole process including agricultur
