Tradable water volumes is one of the basic elements of water-rights trading. In China, water-rights transactions mostly occur in water-deficient areas. However, the water-rich areas are also facing serious water-shortage problems. It is necessary to stimulate the water-rights trading power in abundant water areas to improve water-resource predicament. This paper studied the concept and calculation method of tradable water volumes of industry. First, based on the property rights theory, we analyzed the concept of tradable water volumes, and put forward the preliminary determination of water-rights trading subjects. Then, we defined the tradable water volumes of industry as the difference between the initial water-rights allocation and the water demand of industry. We used the proportion method to calculate the initial water-rights allocation of industry under different runoff frequencies, and grey model (1,1) to predict the water demand of industry. Finally, we applied the calculation method to Changsha city which is in a water-rich area of China. The calculation results contribute to water-resource management in Changsha city. This paper will provide a theoretical basis for researching the tradable water volumes, and promote the development of water-rights trading in China's water-rich areas.
可交易水量是水权交易的基本要素之一。在中国，水权交易主要发生在水资源短缺地区。然而，水资源丰富的地区也面临着严重的水资源短缺问题。有必要激发丰富水资源地区的水权交易能力，以改善水资源困境。本文研究了工业可交易水量的概念和计算方法。首先，基于产权理论，分析了可交易水量的概念，并提出了水权交易主体的初步确定。然后，将工业可交易水量定义为初始水权分配与工业需水量之差。采用比例法计算不同径流量频率下工业的初始水权分配，利用灰色模型（1,1）预测工业需水量。最后，将该计算方法应用于中国水资源丰富的长沙市。计算结果有助于长沙市的水资源管理。本文为研究可交易水量提供了理论基础，促进了中国水资源丰富地区水权交易的发展。
