Abstract: Abstract: Processing and storage of agricultural producing area is an important link in the chain of China agricultural production chain and technical short-board，which is in urgent need to be developed into a supporting technology of the pre-treating industry of agricultural producing area. Technical classification is a frame work to reveal the structural framework and organization relationship of the engineering technical system of processing and storage of agricultural producing area, to orderly guide the technology constitute innovation, development and reserve, and to promote technology integration and promotion, the subject development and industrial upgrade, which is in urgent need of breakthrough in the theoretical methods and classification pragmatic to better guide the engineering technology of processing and storage for the agricultural production area to have a comprehensive and sustainable development. in the base of a grasp on the law of motion and the different technologies constitute special contradiction.The research is based on the broader category of contemporary agricultural produce processing and storage engineering technology, following the principle of reality, hierarchy, stability and openness. Through the analysis of the technical content and technical classification of the processing and storage engineering technology for agricultural producing area, four level line classification method have been determined, which could reflect the professional sequence, technical functions, technical means and technology form of the processing and storage engineering technology for agricultural producing area. According to the complete function of agricultural production area as the basic foundation of classification, the results of horizontal and vertical technology classification have been obtained respectively. The complete function of industrial chain of agricultural production area is to obtain the optimal and comprehensive using for resources, while to obtain high quality and high yield agricultural product efficiently. Realization of the function depends on the technology application and effective operation of every link in the industrial chain. So, horizontally the technology chain is classified into four professional technology categories: primary processing, transportation in producing area, storage in producing area and comprehensive category, while, each technology category includes six professional sequences: comprehensive technology, product processing, management, service, equipment and resource utilization. Through the concrete contents of each technology category are different, the contents of each technology category has been associated with each other to express the classification results simply and conveniently. Moreover, in the longitudinal direction, the technology chain is classified into four levels: large class, middle class, small class and subclass, each level reflects professional sequence, technology infection, realization methods of theology and technology manifestation. The classification results show that the method can accurately reflect the whole picture of the processing and storage engineering technology for agricultural producing area and reveal the technology systems structure and functional characteristics. It has a high reference value to the subject development, industrial upgrading and technology innovation for the processing and storage in agriculture production area.
