Design of an agricultural economic statistical digitalized system

引用

Journal of Southeast University(English Edition) 2008年第S1期24卷 126-131页

作者： Leng, Zhijie Wang, Zhiqiang Wang, Xi Li, Qiang College of Economics and Management Heilongjiang August First Land Reclamation University Daqing 163319 China College of Engineering Heilongjiang August First Land Reclamation University Daqing 163319 China

To improve the efficiency of the management of large farms, a digitalized system of economic statistics is designed based on the Internet platform of the digitalized agricultural integrated system of Friendship Farm, the largest farm in the world. The system can also realize data storage by using the access databank technology. A dynamic website system, based on ASP technology, is used to implement the on-line inquiry of the statistical index of the agricultural economy and the diagrams of the index every year. Furthermore, it can provide the value of comprehensive indicators of farms' economic profits for every year and a trend chart of the comprehensive appraisal of economic development, by using principal component analysis. An early-warning indicator boundary is decided based on the majority principle. The system can realize the farm's terminal data input with effective data-collecting channels and a normative gathering scope and system. This system breaks through the stand-alone database system in agricultural digitalized research to realize the database system in the Internet environment by integrating the existing technologies in China. The system lays a foundation for the further integrated research on the network platform of the digitalized agricultural integrated system in Friendship Farm.
