摘要:

为探讨古树资源特征、空间分布类型以及对其分布特征产生影响的因素,更好地服务城乡生态环境和美丽乡村建设,以聊城市古树资源为例,通过ArcGIS中的渔网分析与核密度分析,研究古树资源的空间分布类型和分布密度,分析土地覆盖类型,以及人口密度、传统村落、古树文化对古树分布的影响。结果表明:聊城市古树共有687株,其中,一级古树65株、二级古树79株、三级古树543株;优势种为侧柏、国槐和枣树等;树高、胸径、冠幅分别集中于>10.0~15.0 m,<1.0 m,>5.0~10.0 m区间范围;正常株数占总株数的71.47%,衰弱株数占总株数的23.73%;古树空间分布类型为聚集分布,包含1个高密集区和6个次密集区,总体呈现“南多北少”、“散点状与多组团状”的古树分布格局。通过研究分析,以期为聊城市古树资源管理、保护提供参考,为美丽乡村建设提供决策依据。

Abstract:

In order to explore the characteristics of ancient tree resources,the types of spatial distribution and the factors affecting their distribution characteristics,it is better to serve the urban and rural ecological environment and the construction of beautiful villages.Taking the ancient tree resources in Liaocheng City as an example,through the fishing net analysis and nuclear density analysis in ArcGIS,the spatial distribution type and distribution density of ancient tree resources were studied,and the land cover type and population density was analyzed.The influence of traditional villages and ancient tree culture on the distribution of ancient trees.The results showed that there were 687 ancient trees in Liaocheng City,including 65 first-class ancient trees,79 second-class ancient trees and 543 third-class ancient trees.The dominant species were Platycladusorientalis,Styphnolobium japonicum and Ziziphus jujuba.The tree height,DBH and crown width were concentrated in >10.0~15.0 m,<1.0 m,>5.0~10.0 m,respectively.The number of normal plants accounted for 71.47 % of the total number of plants,and the number of weak plants accounted for 23.73 % of the total number of plants;the spatial distribution type of ancient trees was aggregated distribution,including 1 high-density area and 6 sub-density areas.The overall distribution pattern of ancient trees was “more in the south and less in the north”,“scattered and multi-group”.Through the research and analysis,it is expected to provide reference for the management and protection of ancient trees in Liaocheng City,and provide decision-making basis for the construction of beautiful villages.
