基于GIS的农业土壤环境监测系统设计与应用

农业土壤环境是农业生产赖以生存的前提，农业土壤环境的优劣直接影响农业产品的质量和产量。本文运用GIS的交叉定位、逻辑查询、空间分析及空间数据库匹配等技术，建立基于GIS的农业土壤环境监测系统，实现对农业土壤环境监测点的管理、质量评价、预警提示以及对农业产品信息和质量的管理与评价，实现对农业土壤环境的动态监测，可以为管理者提供宏观决策支持。本文重点阐述系统的设计。

Design and application of agricultural soil environment monitoring system based on GIS

Agricultural environment is the basis for the survival of agricultural production,whose advantage and disadvantage affects the quality and quantity of agricultural products directly.In this paper,agricultural environment monitoring system is established based on GIS with technologies including Cross positioning,Logical querying,Spatial analysis and Spatial database matching etc.This system realizes the management,quality assessment,alarm in advance and the management and assessment of agricultural products information and quality to agricultural soil environment monitoring stations,and achieves dynamic monitoring to agricultural environment and offer support for managers on macro-decision.The point of this paper is to expatiate the design and implementation of this system.
