A Support System for Crop Water Requirement Diagnosis and Irrigation Decision Making

摘要

A crop water requirement diagnosis and irrigation water requirement decision-making support system was developed which comprised of a data import module, a database module, a model library and diagnosis and decision-making modules. Depending on the information acquisition method, the system can adopt one of the following two modes: online real-time diagnosis and decision making between the monitoring and decision-making systems or offline diagnosis and decision making. Using software technology to jointly use the basic database and the diagnosis and decision-making model library produces more comprehensive decision-making support functions in the system. The decision-making requirements of different users are supported by setting different diagnostic and decision-making strategies. The diagnosis and decision-making support system was developed using Java language and it passed the case test. The results from this study provide methods and tools to improve our knowledge of agricultural irrigation and irrigation water use efficiency.
