摘要
定点观测是野外信息获取的一种重要方式,以田间土壤水分固定观测点信息的远程采集为例,介绍了一种通过GSM公共网实现消息传递控制田间土壤水分传感器,实现远程的田间土壤水分信息采集,并通过以GIS为平台的信息服务中心实现信息采集与灌溉决策无缝集成的系统;最后探讨了利用GIS进行土壤特性分区,并以分区为基础实现土壤水分固定信息采集点布局设计的方法。
Observation with fixed points is an important means for field information collection. Taking remote collection for soil moisture information of fixed observation points as an example, this paper introduced a system, which transfers information through GSM to control soil moisture sensor in field, realizes remote collection for soil moisture information, and attains seamless integration be- tween information collection and irrigation decision by information server center with GIS platform The authors also discussed the soil speciality division through GIS and the design method for distribution of fixed points for soil moisture information collection based on the division in the end.
