Quantitative detection of Salix matsudana inner decay based on stress wave and resistograph techniques
摘要
Abstract
A study was carried out to detect the inner decay of Salix matsudana avenue trees by using stress wave and Resistograph techniques. In each cross section of a tree,10 -12 stress wave sensors were used and 2 -4 directions were tested by resisgraph. The results showed that both the 2D graphs from stress wave detection and resistance curves of Resistograph could determine the location and degree of inner decay in standing trees. A good corresponding relationship was found between them. In each direction,the average resistance and the stress wave velocity were correlated with correlation coefficients above 0. 5. When a whole cross section was considered,a more significant correlation between the average resistance and stress wave velocity was found with a correlation coefficient of 0. 817. These findings lay a foundation of combining these two techniques to build a quantitative indicator to measure the decay degree of standing trees.关键词
