摘　　要：调查区域古树树种、数量和分布状况,并进行保护评估,是国家古树普查建档的重要工作。本研究对西藏日喀则市的古树资源进行了综合调查,获得了该区1098棵古树的基础信息。结果表明:1)该区古树树种隶属于11科18属26种,杨柳科树种占绝对优势,其中以藏川杨为主;2)古树年龄主要分布在100~299年间,1000年以上的稀少,仅8棵,古树大多生长在桑珠孜区和偏远的乡村,受到较多的人为干扰或遭受病虫害的侵害,且缺少一定的保护措施;3)处于高紧迫性保护、中紧迫性保护、低紧迫性保护古树棵数分别有34、147、917棵,分别占所有古树的3.10%,13.39%和83.51%。研究结果为查明区域古树本底资源及科学保护管理提供了参考依据。It was an important work for the national general survey of ancient trees to investigate the species,quantity and distribution in the region,and to carry out conservation assessment.In this study,we made a comprehensive survey of ancient tree resources in Xigaze city,Tibet,and obtained the basic information of 1098 ancient trees in the area.The results showed as follows:1)The ancient tree species in this area belonged to 11 families,18 genera and 26 species,and the Salicaceae species were absolutely dominant,among which the Populus szechuanica var.tibetica was the main.2)Ancient trees were mainly distributed between 100 and 299 years old,and only 8 trees were more than 1000 years old.Most ancient trees growed in Sangzhuzi district and remoted villages,which were subjected to human interference or infringement of diseases and pests,and lacked of certain protection measures.3)The number of ancient trees under high,medium and low urgency protection were 34,147 and 917 respectively,accounting for 3.10%,13.39%and 83.51%of all ancient trees respectively.The results provided a reference basis for identifying the background resources of regional ancient trees and scientific protection and management.
