Design And Development Of Hangzhou Tea Information System

Tea originated from China. China is one of most important countries to produce and export tea in the world. However, with the increase of environmental pollution and application of fertilizers and pesticides in recent years, the tea safety problem has become a crucial factor limiting the development of tea industry in China. The main pollution sources consist of pesticide residues, heavy metals and harmful microorganism. Hangzhou is the capital of tea in China. The West Lake dragon tea is taken as the "king of green tea", and has been one of the most important tea to serve the state guests for a long time. How to manage and control tea safety production from producing bases to teacup has gradually become a focus which is closely related to tea safety. However there is still lack of a perfect and interactive User System to issue, manage, analyses and predict the information of Hangzhou tea.In the present paper, a complete attribute and spatial database for the information of Hangzhou tea is designed and developed at three different scales, Hangzhou city(1:250000), Xihu district(1:50000),and Siling tea garden(1:2000).Based on the Internet,GIS technique,especially WebGIS technique, a Hangzhou tea information system(HTIS) has been established to serve the issue, management and prediction of Hangzhou tea information. THIS is composed of seven modules,including home of system,introduction of Hangzhou,environments for tea production,tea industry association, sale of tea, forbidding supposititious goods ,tea standards.The major functions of THIS include the issue of information and tea news,querying and indexing of data and standards,assessment and predicting/ forecasting of the environmental quality for Hangzhou tea production, measures for controlling tea safety.
