前言沈阳市的东北两陵是重要的古迹风景名胜区, 也是珍贵的世界文化遗产。东陵和北陵的古油松均为清朝建陵初期人工栽植和以后陆续补植的,是国内现存的几个主要古油松群之一,为国家一级古树。东北两陵的古油松大部分为建陵同期栽植,据此推算现有古松树龄应为300至370年。随着古油松树龄的增大和生长环境的变化,到了本世纪初,平均每年死亡的古油松已超过100株。如何采取有效措施, 延长古油松寿命,已成为一个急需解决的问题。
Preface Shenyang’s two northeast mausoleums are important monuments scenic spots, is also a precious world cultural heritage. The ancient Chinese pine of Dongling and Beiling are both planted and replanted one after another in the early period of Jianling in the Qing Dynasty. It is one of the major existing ancient Pinus tabulaeformis in China and is an ancient tree at the national level. Most of the ancient pine forests in both northeast provinces were planted in the same period of Jianling. Therefore, the existing age of ancient pine trees should be 300 to 370 years. With the increase of the age of the ancient Chinese pine and the change of the growth environment, by the beginning of this century, the average annual number of ancient pine trees that have died is over 100. How to take effective measures to prolong the life of ancient Chinese pine has become an urgent problem to be solved.
