| 摘 要： | 干旱造面山东省作物大面积减产和严重的经济损失，其原因主要有三个：一是降水时空分布不均，二是客水量减小，三是温度偏高，蒸散量增加，因此，必须建立健全干旱监测预警服务系统，加快水利建设的步伐，推广旱作节水农业技术。

| Abstract: | The drought is cansing the reduction of crop yield for a large area and heavy economic losses in Shandong Province.Its factors are the inhomogeneous spatial and temporal distribution of precipitation,the decreasing flow capacity of the Yellow River and the increasing transpiration caused by higher temperature.Therefore,it is necessary to build water conservancy projects at top speed and to promote the technology of economizing water usage. |
