[Objective] The research aimed to design and development of system platform of study on relationship between natural phenology and climate based on WEB and GIS. [Method] Relied on the technologies of WEB and GIS, a set of system platform of study on relationship between natural phenology and climate was developed based on the hybrid architecture of C/S (Client/Server) and B/S (Browser/Server). Moreover, its establishing process and functional module were detailedly introduced. [Result] The natural phenology and climate change in Guangxi were research objects of system platform of study on relationship between natural phenology and climate By combining WEB and GIS with database, the primary application of study on relationship between natural phenology and climate was realized. The system used hybrid architecture of C/S and B/S. The four-layer architectures were independent to improve security, stability and maintainability of system. The visual interface on the foreground was simply, clear and easy to use. The generating program of GIS three-dimensional graph on the background was real-time and high-efficiency, providing powerful guarantee for stable and safe operation of phenology research work process. The system had functions of inquiry, analysis, statistical diagram, GIS three-dimensional graph and data export. Through the analysis of natural phenology observation data, the system could find variation rule of natural phenology as three-dimensional space (longitude, latitude and altitude) and its relationship with climate change. [Conclusion] The research laid good foundation for further deeply carrying out application of study on relationship between natural phenology and climate change, and also provided reference basis for recognizing nature and using change rule of phenology to execute production scheduling and strategic decision (seed-introduction and regionalization).
