| Abstract: | The timber demand in China is huge, but it is necessary to improve the timber utilization. Wood non-destructive tes- ting can improve the timber utilization and increase the economic benefits. Electrical resistance testing method can detect decay in standing trees at an early stage conveniently and efficiently. The fundamental principle of electrical resistance testing method was intro- duced in this paper. The research progress of needle-detection method, four-point resistivity（RISE） method and Electrical Resistance Tomography（ERT） were analyzed and summarized. The potential application of electrical resistance testing method in the non-destruc- tive detection of decay in standing trees was forecasted. |
