摘要
江西省旱情频发,干旱严重.为此,根据江西的产流方式为蓄满产流,通过对旱地土壤含水量的预测,结合旱情等级划分标准,建立江西旱地干旱预报模型——缺墒模型,对江西省的旱情发展进行预报,预报的结果与实际情况较吻合.模型具有较高的预测精度,实际运用效果理想.
Jiangxi Province is frequently stricken by serious droughts. Based on the runoff mode and the forecasting result of soil water content on the dry land, we established a drought foreeasting model on the dry land in Jiangxi Province, whose forecasting result is consistent with the actual drought situation in the province. This model is proved to be precise and practical in forecasting the droughts.
