The ancient and famous trees are precious heritage and forest germplasm resources left by nature and predecessors.In this study,the distribution characteristics of ancient and famous trees in Meiling National Forest Park were investigated by the method of each wood gauging.The results showed that the ancient and famous trees mainly distributed in Luoting and Taiping with good ecological environment in terms of horizontal distribution,for 61.40%of the total number.It mainly distributed in the area at elevations below 200 m and accounted for 68.38%in terms of vertical distribution.Taking Cinnamomum camphora as an example,we found that altitude was positively correlated with tree height,negatively correlated with DBH,but no significant correlation with crown width and tree age.It mostly distributed nearby village and forest land and accounted for 67.28%in terms of habitat environment.It distributed mostly in flat slope,sunny slope and flat land and accounted for 37.50%,90.44%and 43.38%respectively in terms of topographic distribution.It was mainly scattered distribution and accounted for 83.46%in terms of aggregated distribution.These results could provide reliable information for the following conservation of ancient and famous trees resources in this region.
