| 摘要 | Ancient and famous trees, known as "green cultural relics", are precious natural and cultural heritage. In order to further grasp the basic characteristics of ancient tree resources in Changning city, understand their spatial distribution, and specifically identifying the environmental factors that significantly influence the distribution of ancient trees, the investigation and analysis of ancient and famous tree resources in Changning City were carried out. ArcGIS tools and map technology were used to establish three databases corresponding to ancient trees, scenic spots and road networks, to analyze the composition and distribution characteristics of ancient tree resources and explore the relationship between geographical factors and the distribution of ancient trees. The results show that there are 489 ancient trees in Changning City, belonging to 27 families, 43 genera and 62 species. According to the type and structure characteristics of ancient trees, there are 30 first-class ancient trees, 73 second-class ancient trees and 386 third-class ancient trees in Changning. According to the habitat and growth characteristics of ancient trees, 306 trees were distributed on the flat slope, 131 on the gentle slope and 21 on the slope. There are obvious differences in the distribution density of ancient trees in Changning City and the dominant species of ancient trees in 18 towns (streets) in Changning City are camphor trees. Then kernel density analysis tool and ArcGIS were comprehensively applied to analyze and evaluate the landscape value of ancient trees in Changning. Based on the resulting ancient tree resource data, landscape evaluation was carried out, formulating a scientific and reasonable scheme, thereby enabling a more vivid presentation of the landscape value of ancient trees in Changning City. |
