摘要：

Measurement of root turnover has been one of the most difficult problems in terrestrial ecosystem studies owing to the lack of an appropriate method. In this paper, a method for measuring intra-seasonal root turnover is described. The recently developed minirhizotron system was adapted and combined with hand tracing of the minirhizotron-produced video tapes. The basic components of a minirhizotron system are briefly introduced. A hand-tracing procedure and the subsequent data analyses are described.
