| 摘 要： | 根据吉林省的连续干旱形势及多年的监测结果,对吉林省中西部的旱情发生、发展规律,进行分析阐述。旱情主要发生在春季4—6月,变化趋势是由西向中西部蔓延。本文通过分析气象因子对土壤含水量的作用,认为用饱和差作主要参数,建立土壤墒情预测预报机制,进行土壤含水量的预测预报是可行的。

| Abstract: | This paper analyses and expounds the law of drought occurred and development,according to the continuous drought period and annual supervising results.Droughts always happen on April to June in the spring season,the change trend is from the west to the middle West,and saturation difference as the main parameter establishing soil moisture forecast mechanism to forecast the soil moisture is feasible through the analysis of weather element function to the soil moisture volume. |
