Abstract:
【Objectives】 To study the resource characteristics and formation mechanism of ancient and famous trees and to provide more pathways for territorial greening and biodiversity conservation. 【Methods】 Taking the survey results of ancient and famous trees in Kaihua County in 2017 as research data, the resource characteristics (quantities, types, protection classes, and spatial distributions) were analyzed by Microsoft Excel. 【Results】 The results showed that there were 7 135 ancient and famous trees in Kaihua County, belonging to 38 families, 74 genera and 108 species;
Cinnamomum camphora,
Liquidambar formosana,
Castanopsis sclerophylla,
Pterocarya stenoptera,
Castanopsis eyrei, and
Cupressus funebris accounted for 60.7% of the total; the first-class ancient trees were the least, only 312, and the third-class ancient trees were the most, with 5978 trees. The age structure of the trees was pyramidal. There were the most ancient and famous trees in Chihuai Town, Suzhuang Town, and Changhong Township, while the least in Daxibian Township and Qixi Town. Ancient and famous trees were mainly distributed in the altitude range of 100~300 m, and the number of ancient and famous trees at an altitude of 100~700 m decreased progressively in a ladder mode. The ancient and famous trees were distributed the most along the northern slope and flat land and equally on the eastern slope and the western slope. The ancient and famous trees located in the village Shuikou and Lailong Mountain accounted for 54.59%. 【Conclusions】 The spatial distribution characteristics of ancient and famous trees in Kaihua County were closely related to the construction sites of traditional Chinese villages. The species selection and orientation distribution of ancient and famous trees were deeply influenced by Fengshui culture. To further improve the living environment and protect biological resources, it is possible to draw on the traditional cultural power of ancient and famous trees and actively carry out publicity for greening and biodiversity conservation.
