基于GIS技术的农产品产地编码研究与应用

Design and application of coding method for crop production places based on GIS technology

在农产品安全生产中为建立科学合理的产地编码体系,应用GIS技术进行产地环境评价的基础上,结合地形地貌、农产品种植等情况,对各种植基地区域进行产地划分.采用以行政区划码和地块编码为主体的方式进行统一编码,引入中图分类法和基地认证情况进行农产品的分类编码,绘制产地编码图,解决了此前产地编码规范性与通用性差的问题.同时,结合农产品的生产、加工、包装和销售等环节,将产地编码以条形码的形式在企业的实际生产中应用,实现农产品安全生产溯源.

Aiming to find a reasonable coding system of production places for safe crop product, the GIS technology was adopted to separate product places into distinct parcels, which was based on environmental assessment, geographical features of landform and distribution of crop planting. The way to combine regionalism code with parcel code was proposed as main body. The methods of Chinese library classification and base authentication were introduced to design this coding system. In addition, the map of production places was plotted with GIS tools. The problem of generalization and standardization of places code was figured out. Furthermore, this code of production places was integrated with the production, processing, packaging and distribution information with spatial data of crop. In a case study, the code of production places was used in form of bar code, tracing and retracing the safety of crop product was achieved efficiently and reliably.
