【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。
[Abstract]:With the development of 3D GIS technology, the application of 3D GIS in agriculture has become the research hotspot of agricultural information technology. Aiming at the demand of precision agriculture development, we take Kaian Town, Nong'an County, Jilin Province as the experimental area, which is the demonstration area of National Spark Plan. Sketch up and Arc GIS techniques were used to simulate the farmland environment in maize precision farming area, and dynamic monitoring of soil temperature and humidity was carried out in 4 layers of farmland, namely, 0 ~ (20) cm ~ (20) ~ (20) cm ~ (20) ~ (20) cm ~ (20) ~ (40) cm ~ (-1) ~ (40) ~ (60) cm ~ (-1) ~ 6080 cm). Based on 3D GIS, a simulation and monitoring system of maize precision operation farmland environment is developed, and the visualization of 3D virtual scene in precision agriculture area is realized. The results show that, This study laid a foundation for dynamic monitoring of soil moisture and precision operation of maize in this area.
