Analysis on the Current Situation of Ancient and Famous Tree Resources in Badong, Hubei and Evaluation of Their Spatial Distribution
【摘要】 [目的]探究湖北巴东古树名木资源现状及空间布局。[方法]调查巴东县古树名木资源现状,并对分布格局进行分析。[结果]巴东现有古树名木2 193株,隶属于44科88属124种。从树种结构分析,分布最广泛的树种为胡桃树(Juglans regia),共有501株,占全县古树名木总数的22.84%。从树龄结构分析,古树名木树龄主要集中在100~299 a树龄段,1、2、3级古树的数量和占比分别为92株(4.20%)、470株(21.43%)和1 631株(74.37%),总体呈“金字塔”型结构。从分布规律分析,古树名木在巴东县12个乡镇均有分布,野三关镇分布最为集中。垂直空间上,分布株数最多的海拔区间为1 099~<1 523 m,数量达到1 255株,占巴东古树名木资源总数的57.23%。[结论]该研究可为湖北巴东县的古树名木保护提供科学依据。
【Abstract】 [Objective]To study the current situation of ancient and famous tree resources in Badong, Hubei and evaluation of their spatial distribution. [Method]The status quo of ancient and famous trees resources in Badong County were investigated, and the distribution pattern was analyzed.[Result]The results showed that there were 2 193 old and famous trees in Badong, belonging to 124 species, 88 genera and 44 families. From the analysis of tree species structure, the most widely distributed tree species was Juglans regia,with a total of 501 trees, accounting for 22.84% of the total number of ancient and famous trees. From the analysis of the tree age structure, the ages of ancient and famous trees were mainly concentrated in the 100-299 a segment. The number and proportion of the first, second, and third-class ancient trees were 92(4.20%),470(21.43%) and 1 631(74.37%),the overall pyramid structure. From the analysis of the distribution law, ancient and famous trees were distributed in 12 towns in Badong County, with the most concentrated distribution in Yesanguan Town. In terms of vertical space, the altitude interval with the largest number of distributed plants was 1 099-1 523 m, and the number reached 1 255,accounting for 57.23% of the total number of ancient and famous trees in Badong. [Conclusion]This study can provide a scientific basis for the protection of ancient and famous trees in Badong County, Hubei Province.
