扼要介绍了以世界气象组织所推荐的适合于干旱半干旱地区的水箱模型总体结构为基础，结合山西省具体情况适当改进后推广使用的效果。实践证明，这样的模型结构至少在山西省半干旱地区使用起来比较成功，且具有明显的优越性。它对同类地区也有参考使用价值。 This paper briefly introduces the effect of promoting and using the water tank model recommended by the World Meteorological Organization suitable for the arid and semi-arid areas based on the overall structure of the water tank and combining with the specific conditions in Shanxi Province. Practice has proved that such a model structure is at least used in the semi-arid areas of Shanxi Province more successfully and has obvious advantages. It also has reference value for similar regions.
