干旱区生态环境知识资源中心

At present, there are hardly any research materials about using the hydrological identification of drought method to establish the irrigation decision information system through monitoring the variation of farmland soil moisture. In this paper, the importance on establishing the automatic measuring and forecast system of soil moisture for the and irrigated area is elaborated. The measuring method and forecast model about soil moisture used for the arid irrigation area are presented. The information transmission and construction and function of system are detailed. This system can be widely used in the similar regions and arid and semi-arid regions. In conclusion, the result shows, the integration and system management to the comprehensive information can be realized that includes soil moisture, water regime, drought situation, irrigation, water demand and agriculture production and so on. Meantime, it can provide the scientific and rational basis for the decision of drought resistance and water-logging control.
