摘　　要：随着三维GIS技术的日益成熟,将三维GIS应用于农业领域已成为农业信息技术的研究热点。针对精准农业发展的需求,以国家星火计划示范区——吉林省农安县开安镇为实验区域,利用Sketch Up和Arc GIS技术,进行了玉米精准作业区农田环境的模拟研究,并对农田地下4个层次(0~20 cm、20~40 cm、40~60 cm、60~80 cm)的土壤温湿度进行动态监测,开发了基于三维GIS的玉米精准作业农田环境模拟监测系统,实现了精准农业作业区三维虚拟场景的可视化展示。结果表明,该研究对该区域土壤墒情动态监测和玉米精准作业的实施奠定了基础。With the gradual maturity of 3D GIS technology,3D GIS applications in agriculture has become a hot topic in the field of agricultural information technology.To satisfy the needs of accurate agriculture development,this paper took the National Spark Program demonstration area-Kaian Town in Jilin Province Nongan County as experimental site,and carried out simulative studies on farmland environment of accurate corn operation area by Sketch Up and Arc GIS technology.And the soil temperature and humidity of 4 underground levels of farmland（0 - 20 cm,20 - 40 cm,40 - 60 cm,60 - 80 cm） were dynamicly monitored.A farmland environment simulative monitoring system was developed based on 3D GIS accurate corn operation area,and a visualization of 3D virtual scene in this area was realized.Results showed that this study had laid a foundation for the dynamic monitoring of soil moisture and implementation of accurate corn operation of this area.
