摘    要:以静海县农业科技园区内一块冬小麦田和玉米地作为试验区,分别按照50m×50m和80m×50m设置格网,共设32个采样点,通过手持定位导航仪GPS MAP76确定点的位置,利用土壤湿度检测仪快速测量各个采样点表层土壤含水量,利用ARCI/NFO的地统计分析模块绘制整个试验区土壤含水量空间分布图,并分析其空间分布规律,可为采取合理的灌溉措施提供科学依据,对于及时调整灌溉和其它农田精细管理措施将具有重要的指导作用。

关 键 词:GPS  GIS  土壤含水量  空间变异  试验研究

Abstract:Taken part of Jinghai Agricultural Sci-Tech Garden as research area,in the winter wheat field sample points were set as 50 m×50 m grids and 80 m×50 m in maize field,thirty-two was the total number of samples.All points were sited by GPS MAP76 machine.Soil moisture data of surface was measured by sensor for each point.We mapped the spatial distribution of soil water content for winter wheat and maize fields by using Geo-statistical Analyst model of ARC/INFO software,and also analyzed the spatial distribution regulation of soil moisture.The analysis results provided reference for irrigation adjustment and precise farming management.
