摘　　要：为了解决墒情监测中便携式监测仪数据存储、发送困难及墒情实时监测和分析等问题,建立了基于无线传感器网络和WebGIS的墒情监测系统。系统以STC单片机为核心芯片,结合GPRS模块、GPS模块,通过无线传感器网络技术,实现土壤水分数据的实时监测及无线传送。建立了数据库,接收监测点数据。并以SuperMapIS.NET和SQLServer2005为开发平台进行二次开发,将GIS技术与墒情监测结合起来,根据作物耕作深度、作物生长期对土壤含水量进行判断,得出墒情结果。实现墒情监测点信息、土壤含水量曲线图、等值线分布图在Web服务器上的显示。墒情监测系统的建立和使用,对农业生产有深远的意义。In order to solve the difficult problems such as data storage, sending of portable test instruments and real-time monitoring and analysis in soil moisture monitoring. Soil moisture monitoring system based on wireless sensor networks and WebGIS technology was established. The design of the whole system, which had STC singlechip as the core chips, GPRS module and GPS module were integrated. Real-time acquisition and wireless transmission of soil moisture data were achieved through the wireless sensor networks technology. Database was set up to receive data. GIS technology was combined with soil moisture monitoring by the secondary development of SuperMap IS.NET and SQL Server technology. The results of soil moisture were obtained through the analysis of the content of soil water based on the depth of soil and growing time of crops. The shows of the information of monitoring sites, the curve of soil moisture content and isoline map on Web server were realized. The foundation and use of the system had far-reaching implications for agriculture production.
