摘要
本研究基于2022年靖安县古树名木调查数据,对该县古树名木分布数量、种类、空间分布、结构特征等资源特征进行分析.结果表明,靖安县分布有古树名木2 939株,隶属于22科33属39种;以樟树(Camphora officinarum)、苦槠(Castanopsis sclerophylla)、马尾松(Pinus massoniana)、枫香(Liquidambar formosana)、柏木(Cupressus funebris)等乡土树种为主;主要分布于乡村,数量为2 838株;以海拔0～100 m分布为主,且随着海拔上升数量呈递减趋势.树龄、胸径、冠幅、树高结构均呈金字塔形,以三级古树为主,树龄集中在100～200 a,胸径集中在60～100 cm;古树生长势与生长环境、权属、海拔等因素存在相关性,海拔与生长势呈正相关,生长场所与生长势呈负相关,即从乡村到城区,古树名木的生长势趋势由正常转向衰弱.建议及时对衰弱古树名木开展保护和复壮,对具备历史文化的古树积极展开文化宣传.
Abstract
Based on the survey data of ancient and famous trees in Jing'an County in 2022,the resource characteristics such as the number,species,spatial distribution,structural characteristics and health status of ancient and famous trees were analyzed.The results showed that there were 2 939 ancient and famous trees in Jing'an County,belonging to 22 families,33 genera and 39 species.Camphora officinarum,Castanopsis sclerophylla,Pinus massoniana,Liquidambar formosana,Cupressus funebris were the main local tree species;the number of ancient and famous trees mainly distributed in rural areas was 2 838.The ancient and famous trees were mainly distributed at an altitude of 0～100 m,and the number of ancient and famous trees decreases as the altitude rises.The age,diameter at breast height(DBH),crown width and tree height structure of ancient and famous trees were pyramid shaped.The tree age was concentrated in 100～200 a with mainly grade 3 old trees,and the DBH was concentrated in 60～100 cm.The growth potential of old trees was correlated with the growth environment,ownership,elevation and other factors,the elevation was positively correlated with the growth potential,and the growth place was negatively correlated with the growth potential.,from the countryside to the urban area,the trend of the growth potential of the old and valuable trees has shifted from normal to weakened.It was recommended to protect and rejuvenate the weakened old and valuable trees in a timely manner,and actively carry out cultural publicity for the old trees with history and culture.
