RZWQM模型介绍及其应用进展

Introduction and Application Progress of the Root Zone Water Quality Model(RZWQM)

首先总述了美国RZWQM的研制过程、模拟功能以及模拟的流程,随后分别介绍了RZWQM 6个主要过程:物理过程、土壤化学过程、养分过程、杀虫剂过程、作物生长过程和管理过程;讨论了模型应用过程的注意事项,并探讨了RZWQM98新版本特征;最后对RZWQM模型的应用进展进行了综述,认为RZWQM在模拟作物生长和水分、养分和杀虫剂在作物根区内的运移是很有用的工具。

The paper summarized the development, function and flow of the Root Zone Water Quality Model（RZWQM ）. RZWQM is made up of six major components, described as physical processes, soil chemical processes, nutrient processes, crop production processes, pesticide processes, management processes. The problems in simulating process and the features of RZWQM98 were discussed, and the apphcation progress of the model was also summarized. The model was a useful tool in simulating crop development and the movement of water, nutrients and pesticides over and through the root zone.
