| 摘 要： | 用水分生产率值衡量农田所消耗水分的有效利用程度已被广泛地利用，由于以何值作为计算机农田水分的消耗并没有一个统一的说法，因而极易产生误解。介绍目前国内外文献引用最多的几种水分生产效率的确定方法，以及如何理解其含义并正确加以应用。

| Abstract: | Using water productivity to measure the effective utilization degree of water consumption of farmland,has been used widely.But due to taking what value as the water consumption of farmland,there is no unified statement,therefore some misunderstanding will be produced.Now several method of determining water productivity,which are recently used at home and abroad,are described.And how to understand its meaning and correctly using it are also discussed. |
