摘要:
 为进一步加强对天水市伏羲庙内古侧柏的保护，运用TRU树木雷达对伏羲庙28棵古侧柏树干空洞情况进行了检测。结果表明，28棵古侧柏树干都不同程度地出现了空腐，其中轻度空腐的占25%、中度空腐的占67.85%，重度空腐的占7.14%。同时对古侧柏健康地上部分进行诊断，利用层次分析法得出完全健康的为0株，较健康的有17株，占比60.71%；不健康的6株，占比21.43%；显著不健康的4株，占比14.29%，濒临枯死的1株，占比3.58%。综合古侧柏地上部分生长的健康状况评估结果和空洞情况结果进行分析得出，古侧柏的树龄与健康程度之间没有明显的相关性，树龄只是导致树衰弱的主要因素，不是重要因素。空洞情况与健康程度之间存在一定的相关性，在树龄较小情况下，空洞越小的健康程度越大，但有少量古侧柏之间关系呈负相关，主要原因可能是地下根系较为发达，树冠茂盛，矿物质、水分和光合作用的能力较强，部分古侧柏病虫害情况较为严重。基于以上研究结果，提出伏羲庙古侧柏保护建议措施，为进一步研究古树、保护古树的措施提供借鉴。
Abstract:
 In order to further strengthen the protection of the ancient Platycladus orientalis trees at the Fuxi Temple in Tianshui City,TRU tree radar was used to detect the trunk cavities of 28 ancient P.orientalis trees at the temple.Trunk cavities were found in all 28 ancient P.orientalis trees with different degrees,among which,the number of mild，moderate and severe cavities accounted for 25%，67.85% and 7.14%,respectively.The healthy examination of aerial parts by analytical hierarchy process demonstrated no completely healthy trees were found,17 trees were in relatively healthy level,accounting for 60.71%,6 were in unhealthy level,accounting for 21.43%,4 were in significantly unhealthy level,accounting for 14.29%,and 1was on the verge of death,accounting for 3.58%.Based on the health assessment of the above-ground part and the cavity status,no significant correlation was found between the tree age and health level,although there existed certain correlation between the cavity and the degree of health level.At relatively young stages,the smaller the cavity,the more healthy.However,negative correlation was also observed in a small number of trees,which may be due to the more developed underground root system.The tree canopy is luxuriant,with strong mineral,moisture and photosynthetic capacity,and some of the ancient Platycladus orientalis diseases and insect pests are more serious.Based on the above research results,the protection measures of ancient Platycladus orientalis trees at the Fuxi Temple were put forward to provide reference for further research onthe measures to protect ancient trees.
