[目的]对蔬菜种植元数据模型信息描述进行研究。[方法]针对蔬菜种植过程中品种资源、农田环境、病虫害防治和田间管理等数据在采集、管理和分析时出现的数据标准不一致、数据格式多样、数据共享效率低等问题,在分析蔬菜种植各环节需涉及的数据基础上,以XML/XML Schema为技术手段,提出蔬菜种植元数据描述方案,构建蔬菜种植元数据模型。[结果]建立了蔬菜种植元数据模型,利用XML Schema技术实现了对蔬菜种植元数据模型的信息描述。整个元数据模型拥有7个一级数据分类,包含800多个信息描述点,能够完整记录与蔬菜种植相关的品种资源、种植环境、田间管理和病虫害防治等信息。[结论]为蔬菜GAP管理、设施蔬菜、食品安全追溯等行业应用提供数据采集、管理和共享的标准规范。
[Objective] The research aimed to describe the information of vegetable planting metadata model. [Method] In order to solve the problems of inconsistent data standards, diverse data formats and low data sharing efficiency during the collection, management and analysis of variety resources, farmland environment, pest control and field management during vegetable cultivation, Based on the data to be involved and the XML / XML Schema as the technical means, a description scheme of vegetable planting metadata was proposed and a vegetable planting metadata model was constructed. [Result] The establishment of a vegetable planting metadata model, the use of XML Schema technology to realize the vegetable planting metadata model information description. The entire metadata model has seven primary data categories with more than 800 information descriptive points that provide a complete record of information on variety resources, plantation environment, field management and pest and disease control associated with vegetable cultivation. [Conclusion] The standards for data acquisition, management and sharing for GAP management of vegetables, facilities vegetables, food safety traceability and other industries were provided.
