| 摘 要： | 从农业生产实际出发,引入能够判断作物受旱程度的毛管破裂含水量、凋萎含水量等土壤含水量指标来确定干旱指标,根据土壤水分平衡理论,建立干旱监测预警模型,利用自动站气象资料和降水趋势预报对干旱情况进行判别和分析,并采用Surfer软件对干旱情况进行直观的图形显示.

| Abstract: | Proceed from the real situation of agricultural producing, introduce the water content of capillary breaking, wilting as well as soil, which can judge drought degree of agronomic crop, to define drought indicator. Based on the soil moisture counterpoise theo- ry, this paper sets up a model of drought to monitor pre - warning, utilizes automatic data of weather station and forecast of precipitation trend to diffemtiate and analyze the drought circumstances, and adopts software SURFER to illustrate the drought circumstances. |
