据调查,泰山现有古树总数为18 198株。其中,正常古树占25.4%,轻衰和中衰古树占古树总数的63.7%,重衰和濒危古树所占比例为9%,死亡古树比例达到1.3%,急需保护古树935株。对187株死亡古树的死亡原因分析结果表明,古树自然死亡比例为2.7%,病虫害致使古树衰弱死亡比例为42.8%,工程建设破坏（建筑施工、修路、水泥硬化等）致死比例为25.7%,污水污物（厕所污染,建筑、生活垃圾）致死比例为8.6%,郁闭致死比例为6.4%。分析查找古树衰弱及死亡原因,采取相应的古树保护措施至关重要。

According to survey data, there are 18 198 old trees in Tai Mountain, among which 25.4% are in normal condition, 63.7% are in light attenuation and decline, and 9% were in the condition of heavy decline and endanger- ment, while the proportion of dead trees reaches 1.3%. There are 935 old trees in urgent need of protection. Through the death cause analysis of 187 dead old trees, the results showed that 2. 7% of them perished owing to natural mor- tality, 42. 8% perished because of diseases and pests, 25.7% perished due to construction damage (construction, roads building, cement hardening ) , 8. 6% declined and died from pollution ( toilet sewage, garbage of construction and living), and the death cause of 6. 4% was canopy. Therefore, it is essential to analyze and find the reason of old tree decline and death and take corresponding protection measures.
