【Abstract】 A total of 1 384 ancient trees with a breast diameter of ≥80 cm were recorded in a survey of the ancient trees of Carpinus cordata,Abies holophylla and Pinus koraiensis forests formation plant in Lushui River Jilin Province. Among them,46 were Abies holophylla,the largest breast diameter was 131. 6 cm,the tree age was between 212 and 346 years.Pinus koraiensis was 207,the largest breast diameter was 130. 2 cm,the tree age was between 314 and 490 years. Fraxinus mandshurica was 459,the largest breast diameter was 157 cm,the age of the tree was between 256 and 432 years. 1 strain of Phellodendron amurense,80. 2 cm of breast diameter,220 years old. 193 strains of Tilia amurensis,125. 8 cm of the largest breast diameter,between 305 and 488 years old. 387 strains of Quercus mongolica,the largest breast diameter172. 0 cm,the age of the tree was between 274 and 601 years. 91 strains of Ulmus pumila Linn. var. suberosa Turcz,the largest breast diameter was 130. 2 cm,and the age of the tree was between 204 and 337 years. The ancient tree level can be divided into 4 national ancient trees,608 national second-class ancient trees and 772 national third-level ancient trees. The basic data for the protection of ancient tree resources in the region and the development of forest health bases,climate change,volcanic impacts and forest succession were provided.更多还原
