摘 要：
根据2017年莲都区古树名木普查数据,从树种、树龄、空间分布及生长状况4个方面分析和评价全区古树的现状。结果表明:莲都区古树数量多且种类丰富,共有古树名木资源2156株,分属28科52属66种。马尾松(Pinus massoniana Lamb.)、樟(Cinnamomum camphora(Linn.) Presl)、枫香(Liquidambar formosana Hance)、苦槠(Castanopsis sclerophylla(Lindl.) Schott.)、南方红豆杉(Taxus wallichiana Zucc.var.mairei(Lemee et Levl.) L.K.Fu et Nan Li)、榧树(Torreya grandis Fort.ex Lindl.)、柳杉(Cryptomeria japonica(L.f.) D.Don var.sinensis Miq.in Sieb.et Zucc) 7种古树株数最多,是优势树种,占总株数的85.9%;全区一级古树127株、二级古树335株、三级古树1694株,古树株数和种数在年龄上呈现出"金字塔"型分布,总体趋势是年龄越大,株数和科属种数越少;全区古树空间分布以散生分布为主,散生古树占总株数的63.2%,群生古树占比36.8%,大多数古树分布在农村,极少数分布于城区,城市化发展最早的白云街道和万象街道无古树群分布且古树株数最少,说明工业发展和城市化进程是古树群居破碎化和古树株数减少的主要原因;全区古树生长状况良好,生长正常、衰弱、濒危、死亡的古树分别为1985、115、30、26株,分别占总株数的92.1%、5.3%、1.4%、1.2%。从多角度全面分析了全区古树生长现状,可为古树名木保护工作提供参考。

摘 要：
According to the census data of ancient and famous tree of 2017 in Liandu district,characteristics of ancient and famous tree were analyzed and evaluation in the region from four aspects including species,age,spatial distribution,growth status.The results showed that:there were abundant in quantity and species of ancient tree in Liandu district,which there were 2156 ancient and famous existing tree,belonging to 28 species,52 genera and 66 families,with the seven dominate species including Pinus massoniana Lamb,Cinnamomum camphora(Linn.) Presl,Liquidambar formosana Hance,Castanopsis sclerophylla(Lindl.) Schott.,Taxus wallichiana Zucc.var.mairei(Lemee et Levl.) L.K.Fu et Nan Li,Torreya grandis Fort.ex Lindl,Cryptomeria japonica(L.f.) D.Don var.sinensis Miq.in Sieb.et Zucc are largest number,accounting for 85.9% of the total number.There were 127 plants of Grade Ⅰthat more than 500 years old,335 plants of Grade Ⅱ that between 300 and 500 years old,1694 plants of Grade Ⅲ that between 100 and 300 years old in the region,the number of trees and species in terms of age presents a pyramid-type distribution,with the overall trend is that the age higher,the number of trees,species,genera,families less.From spatial distribution status,the ancient tree mainly distribution scattered,accounting for 63.2% of the total number,ancient tree in group have 36.8% Percentages,the vast majority ancient tree distribution in village,relatively there rarely distribute in inner cities,the earliest development of the Baiyun street and Wanxiang street had no ancient tree in group and the number of ancient trees was the least,this can explain industrialization development and urbanization course is the main reason resulted group of ancient tree fragmentation and the number of ancient tree decreased. The ancient tree in the region growth in good condition,growing normally,weakly,poorly and death,each with 1985,115,30,26,accounting for 92. 1%,5. 3%,1. 4% and 1. 2% of the total number. Comprehensive analysis the growth status of ancient tree in the region from many angles,and it can provide the theoretical basis for protection the ancient and famous tree.
