A Study Of The Construction Of Rural Information Service Platform Based On Web In China

Agricultural and rural informatization is essential to the development of modern agriculture and countryside in China. The construction of agricultural and rural information service platform based on web is an emerging domain in our country. After more than a decade's development in this field, our country has made some satisfactory accomplishments concerning agricultural and rural informatization. However, there is still a long way to go. It can't meet the requirements of farmers and the economic growth. The exploitation of rural information resources has long been a weak point in agricultural and rural informatinization in China, especially the problem of having no access to regional rural information resources and the problem of irrational allocation of information resources. Because network is the effective vehicle for sharing information resources, the construction of the open rural information service platform can break down the self-enclosed situation, make the best of rural information resources and narrow the digital divide between the city and the countryside. The theoretical research on rural informationizaion and its application focus on devising the most appropriate construction scheme for integrating and sharing rural information resources to serve the government , farming economic organizations and farmers by providing e-government platform, e-commerce platform and network information service platform.The dissertation approaches the subject from two perspectives: from the theoretical perspective of rural informatization and from the practical perspective of constructing rural network information service platform. There are six chapters in this dissertation. The first chapter is the introduction, which justifies the chosen subject and presents an overview of rural informatization and rural network information service platform. And expounding on need analysis and the overall framework of the study, including a brief introduction to the researched region and its rural informatization, and the research approaches as well as techniques involved. Chapter 2 discusses the construction of network control center in theory and in practice, which covers the design and safety insurance of the project of the equipment center, the design and implementation of the system integration, and the planning of the platform security system. Chapter 3 illustrates the design and implementation of the regional four-level interactive network system, which dwells on the design and implementation of sharing information resources within four-level regional network. Chapter 4 explores the design and implementation of e-commerce system of agricultural produce and farm implements etc, including the definition, function, and development of e-commerce and agricultural e-commerce, the detailed analysis and design of agricultural e-commerce system and practical exploration of its four specific functions: online trade in agricultural produce, online auction, the supply and demand information management and market price information management. Chapter 5 elaborates on the design of rural spatial information release system based on WebGIS, which outlines the theoretic foundation and the significance of designing rural spatial information release system in the researched region, analyzes the objectives of constructing such a system, techniques involved and target users, and conducts a research on the configuration of the system, functions and database framework. Chapter 6 is the conclusion, covering the prospects of rural informatization development as well as the characteristics and originality of the study.This study concludes from the above discussion that rural informatization deserves the attention and participation of the whole society since it promotes agricultural modernization and the construction of new countryside. In addition, it is imperative to construct a comprehensive rural information service platform based on web by integrating computer technology, network technology,"3S"technology and communication technology to serve the farmers and governments etc. in that region. By so doing, such a comprehensive, integrated network platform will not only satisfy the requirement for information service, but also minimize the waste in redundant construction of rural information resources, thus promoting the healthy development of rural politics, economy, society and culture in the region.
