对水的需求在不断增加,而现有的供应量却或多或少地保持不变。在这种情况下,迫切需要在水资源管理方面采用有效的技术,以最佳方式利用现有的水资源。干旱条件下的水资源管理在印度等热带地区非常重要,那里三分之一的作物面积受到频繁干旱的影响。本文论述了干旱管理专家系统的开发和应用。一个线性规划模型被用来产生最佳的种植模式,从过去的干旱经验,也从合成干旱发生。这些政策与专家的知识一起被纳入一个专家系统。利用这一方法,可以识别出当前情况下的干旱程度及其与已识别干旱事件的相似性,并能够得到相应的管理策略。
Demand for water is increasing continually, whereas available supplies are more or less constant. Under these circumstances there is an urgent need to introduce efficient techniques in water resources management for optimal utilization of available water. Water management under drought conditions assumes great importance in a tropical region such as India, where one‐third of the cropped area is affected by frequent droughts. This paper deals with the development and application of an expert system for drought management. A linear programming model was used to generate optimal cropping patterns from past drought experiences as also from synthetic drought occurrences. These policies together with the knowledge of the experts were incorporated in an expert system. Using this, one can identify the degree of drought in the current situation and its similarity to the identified drought events and be able to get the corresponding management strategy.
