摘要
城市古树资源不仅是区域文化的重要载体,更是城市珍贵的自然资产。对六安市建成区范围内古树资源展开实地调查,共统计古树872株,包括三级古树10株,后备古树862株。872株古树隶属于28科37属43种,树种中株数最多的是水杉,共305株。空间分布上,金安区三级古树8株,后备古树599株,裕安区三级古树2株,后备古树263株,主要分布于六大土地类型中,其中公园绿地与学校数量分布最多,分别为419株、258株;树龄结构中,古树年龄主要集中在60~69年,有629株,占总株数的72.13%;生长状况上,2株三级古树濒危、5株后备古树生长势较差、3株后备古树生长环境差,但三级古树均有地上保护措施,后备古树均未纳入古树资源管理体系中。最后,依据调查结果分析,对建成区内古树资源保护工作提出合理化建议,确保下一步古树资源保护工作的精准开展。
Ancient tree resources are not only the important carriers of regional culture, but also precious natural assets of the city. In this study, through the investigation of the status quo of ancient tree resources in built-up area of Lu’an City, there are 872 ancient trees, among which 10 and 862 trees are categorized as class Ⅲ and Subsequent ancient trees respectively. They belong to 28 families, 37 generas and 43 species, and the most common species is Metasequoia glyptostroboides with 305 trees. In terms of spatial distribution, there are 8 and 599 trees are categorized as class Ⅲ and Subsequent ancient trees respectively in Jin’an District, and 2 and 263 trees are categorized as class Ⅲ and Subsequent ancient trees respectively in Yu’an District. They are divided into six land types and the number of parks and schools is the largest, which are 419 and 258 respectively;in terms of tree age, the age of Ancient tree is mainly concentrated between 60 and 69 years, with 629 trees, accounting for 72.13% of the total number;in terms of growth status, 2 of class Ⅲ ancient trees are endangered, and 5 of subsequent ancient trees have poor growth potential. What’s worse, 3 of subsequent ancient trees have poor growth environment. However, class Ⅲ ancient trees have overground protection measures, and the Subsequent ancient trees are not included in the management system of ancient tree resources. Finally, based on the analysis of the survey results, reasonable suggestions are put forward for the protection of ancient tree resources in the built-up area, which will contribute to the accurate development for further protection of ancient tree resources work.
