茶叶产地环境评价及其信息系统构建研究

我国是茶叶的重要生产基地,近年来茶叶中重金属和农药超标现象时有发生,已成为限制我国茶叶出口和发展的重要障碍.茶叶生长的产地环境质量则成为研究解决我国茶叶安全问题的一个重要研究领域,但目前对产地环境信息缺乏一个良好的交互式用户系统进行发布、管理和预警.本文以杭州茶叶产地环境为例,通过利用WebGIS和WWW技术构建了一个基于WebGIS的茶叶产地环境信息系统,可以提供产地数据查询、时空演变、环境评价、预测预警等模块,以期为茶叶产地环境及其安全生产的管理、规划和预测预警提供依据.

Quality assessment and information system building of producing base for tea

China is one of most important countries to produce tea.However,with the increase of environmental pollution in recent years,the tea safety problem has become a crucial factor limiting the development of tea industry in China.The environment for tea production 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 and predict the quality of producing bases.In this study,taking the tea producing bases in Hangzhou as an example,an information system based on WebGIS and Internet techniques has been developed.The functions of this system include data query,spatial-temporal change,environmental assessment,predicting and forecasting,etc.
