抽象的。为了满足常常相互冲突的环境和经济目标，墨累盆地的水资源面临着越来越大的压力。政府作为“环境管家”，有多种管理选择，包括水交易和储存水，直到水能得到最大的利用，偶尔还可以将水卖回给灌溉者。这有时被称为反周期交易。为了检验上述方案的潜力，开发了一个简单市场中的水交易和银行业务模型。该模型将流域水文学模型与驱动土地利用实践和水需求的经济信息相结合。模拟用于在战略层面探索这些选项。在积极主动的环境管理者存在的情况下，考虑了增加高地造林和气候变化对流域水文的潜在影响。结论是，在权利受到限制的系统中，最具成本效益的管理系统可能会涉及反周期交易。
ABSTRACT. Murray Basin water resources are under increasing pressure to satisfy often conflicting environmental and economic objectives. Governments, as the “environmental steward,” have several management options including water trading and banking water until it can be used to greatest effect and occasionally selling water back to irrigators. This is sometimes known as counter‐cyclic trading. To examine the potential of the above options, a model of water trading and banking in a simple market is developed. The model combines a catchment hydrology model with economic information that drives land use practice and demand for water. Simulations are used to explore these options at a strategic level. The potential impacts of increased upland afforestation and climate change on catchment hydrology in the presence of a pro‐active environmental steward are considered. It is concluded that in a system where entitlements are capped it is likely that the most cost‐effective management system will involve counter‐cyclic trading.
