The method of Substance Flow Analysis (abbreviated as SFA) provides a helpful tool for the study of the industrial metabolism of a certain metal within a regional level. Lead is one of the important strategic commodities of national economic development in China. In this work the flow of lead in China, 2006, was traced within the STAF model, and the situation of production, consumption and recycling of lead resources in China were introduced. The SFA is performed on lead flows during its one year life cycle in detail, and several main average indexes from 2000 to 2006 were calculated as following: PZ=79.28%、PS=19.08%、MZ=148.91%、MS=30.25%、R=0.8349t/t and S=0.1949t/t. As one of the biggest producer and consumer of lead in the world, from a long-term point of view, China is still facing the problem on depletion of lead resources. How to increase the resource efficiency is a significant issue for lead industry of China. Based on the result, several advices were proposed in the paper, aiming to contribute important reference information for the industrial metabolism and resource management and recycling of lead industry in China.
