扬州瘦西湖景区古树健康监测与评价

Monitoring and Evaluation of the Ancient Trees' Health Condition in Slender West Lake Scenic Area of Yangzhou

使用智能无损检测技术对扬州瘦西湖风景区157棵古树进行全方位健康状况评价。采集的树木资源信息包括树种、周长、树高、断层图像、微钻阻力以及根系分布图。对于同一棵树木,在离地面不同高度使用德国Pi CUS进行应力波无损检测。根据应力波检测结果,再使用美国TRU探地雷达及德国RESISTOGRAPH微钻阻力测试仪检测,以便保证检测结果的一致性。结果表明,景区88.59%的古树健康状况良好,个别树木存在空洞以及严重腐朽。文章分析了检测结果并做出总体评估,简要讨论了养护措施。

In this article, a comprehensive evaluation on the health condition of 157 ancient trees in Slender West Lake Scenic Area of Yangzhou was made by adopting intelligent non-destructive testing technology. The collected information of ancient trees involves tree species, perimeter, tree height, fault images, micro-drilling resistance and root distribution. For each tested tree, stress wave test was conducted from different heights a- bove ground using PiCUS tool. According to the stress wave testing results, penetrate ground radar scanner TRU and micro-drilling resistance testing equipment RESISTOGRAPH were applied at the same height as stress wave testing to ensure the consistency of detection results. The results show that 88.59% of ancient trees are in good condition and cavity or serious decay exists in individual trees. The test results are analyzed and generally evaluated. In addition, the corresponding conservation measures are briefly discussed.
