The bee products quality monitoring and tracing information service platform was researched and developed. This paper describes the design concept and critical technologies for the construction of the bee products quality monitoring and tracing information service platform. The system has functions of remote information collection, production-purchase-processing automatic coding, bar code generation and identification, product quality tracking and tracing, information release, origin evaluation, market prediction, and analysis based on Geographic Information System (GIS), providing information technology(IT) tools for bee products quality safety control and quality tracing in China.

In order to deal with the uncertainty of evidences mostly existing in pineapple disease identification system, a reasoning model based on evidence credibility factor was established. The uncertainty reasoning method is discussed, including: uncertain representation of knowledge, uncertain representation of rules, uncertain representation of multi-evidences and update of reasoning rules. The reasoning can fully reflect the uncertainty in disease identification and reduce the influence of subjective factors on the accuracy of the system.

In this paper, a new spectroscopy technology named terahertz time-domain spectroscopy (THz-TDS) is introduced, which is used in food safety. We describe a coherent subpicosecond THz spectroscopy system based on non- resonant optical rectification for the generation of THz radiation. As an example, we measured absorption spectrum of water vapor by THz-TDS in frequency from 0.5 to 2.5 THz, The experiment demonstrated that the spectroscopy resolution of system was up to 0.0001THz, which can be measured vegetable pesticide residual, for it neither need sample pretreatment nor cause pollution.

The concept of county region economy and its informationization were limited. The characteristics and functions of county region economy informationization were pointed out. On the basis of analyzing the present situation and the existent problems, the developmental strategy of county region economy informationization in China were put forward from guiding ideology, basic principles, system frame and the way of implementation.

The information in rural areas of Shijiazhuang survey results showed that there were greater differences between urban and rural areas in the information equipment ownership and consumption of information, the way of farmers understanding information was rather narrow and concentrated. The information gap existed between urban and rural areas. This paper raised the model of cultivating the information-based.

In the paper phase correlation algorithm based on Fourier transform is applied to the traceability barcode identification, which is a widely used method of image registration. And there is the rotation-invariant phase correlation algorithm which combines polar coordinate transform with phase correlation, that they can recognize the barcode with partly destroyed and rotated. The paper provides the analysis and simulation for the algorithm using Matlab, the results show that the algorithm has the advantages of good real-time and high performance. And it improves the matching precision and reduces the calculation by optimizing the rotation-invariant phase correlation.
