摘要
为摸清拉萨市林周县古树名木资源及其分布格局,探究古树名木现状,提出科学切实的保护对策,2023年课题组就林周县古树名木资源开展调查.结果显示,林周县共有古树名木2 539棵,其中名木、一级古树和二级古树分别为0、1 515棵和768棵,古树后续资源(三级古树)256棵,隶属6科8属21种;鉴定为优势古树的有8种;树龄高于1 000年的一级古树49棵;空间分布呈聚集型,南北差异显著,86.25%的古树分布于林周县北部,且北部的热振国家森林公园具有最高的空间聚集性,人口密度和坡度等因素均对古树空间分布产生了显著影响.
Abstract
In order to understand the resources and distribution pattern and current situation of ancient and fa-mous trees in Lhundrup County,Lhasa,and to propose a scientific and practical protection measures,a compre-hensive survey on ancient and famous trees was conducted in Lhudrup County in year 2023.A total of 2 539 an-cient and famous trees was recorded,belonging to 6 families 8 genera and 21 species,in Lhudrup County includ-ing 1 515 first-class and 768 second-class ancient trees,and 256 following-up resources of ancient trees(third-class ancient trees).There are 8 species identified as dominant ancient trees and 49 first-class ancient trees are over 1 000 years old.The ancient trees distributed as clustered pattern spatially with significant differences in the distribution of ancient trees between the north and south part of Lhudrup County.86.25％of the ancient trees are distributed in the northern part of Lhudrup County,especially the northern area known as Ra-Dreng National Forest Park has the highest spatial clustering pattern.The factors such as population density and mountain slope have a significant impact on the spatial distribution of ancient trees in the study area.
