摘要
利用GPS技术建立了土壤水分监测系统,并利用该系统对位于雷州半岛的广东省国有幸福农场的土壤旱情进行了监测,得到0~30cm深度范围内土壤水分分布图,这对加强土壤水分的田间管理、合理分配有限水资源均有实际意义。
Drought and water-lack have become the main factors that restrict the development of agriculture in China and resulted in the losses of foodstuff one hundred billion kilograms every year. It抯 very important to management the field water utilization for saving water. To monitor soil moisture content based on GPS and GIS technology was studied in Xingfu Farm, Leizhou Peninsula, South China, which belongs to southern dry land agriculture area, hilly and seasonal drought. GPS and GIS technology was used for mapping soil moisture content in Xingfu Farm. The maps of soil moisture content was used for controlling the water supplementary.
