摘要

在查阅历史资料的基础上,采用实地调查与走访当地群众相结合的方法,对广州从化市街口、城郊、江埔、太平、鳌头、良口、吕田、温泉和东明9 个管护区的古树名木进行逐株调查。结果表明:从化市古树名木分布范围广,9个管护区均有分布,但种类数和株数有较大差异;古树和大树主要分布在风水林中,并以群落的形式存在。从化市有古树名木2 104 株,隶属于41 科72 属90 种;其中,含5 种及以上的科有壳斗科(Fagaceae)、樟科(Lauraceae)、大戟科(Euphorbiaceae)、桑科(Moraceae)和柏科(Cupressaceae);无患子科(Sapindaceae)和壳斗科的古树名木株数较多,分别有553 和451 株;锥属[Castanopsis (D. Don) Spach]的古树名木种类最多(9 种);在从化市的古树名木中,荔枝(Litchi chinensis Sonn.)和红锥(Castanopsis hystrix A. DC.) 的株数较多,分别为500 和301 株;绝大多数古树名木为乡土树种,种数达到89 种。树龄在100 a 以上的古树共有2 000 株,其中,树龄为100 ~ 199、200 ~ 299、300 ~399、400 ~499 和500 a 以上的古树分别有1 394、434、162、4 和6 株。62. 95% 的古树生长表现良好,生长表现一般的古树占总株数的30. 80%,而生长较差和濒死的古树分别仅占总株数的4. 65% 和1. 60%。根据调查结果,对从化市古树名木的管理和保护提出了一些建议。

Ancient and big trees mainly distribute in the geomantic omen forests and exist in form. of community.

Among these trees, 62. 95% are growing well, 30. 80% are growing generally and the trees growing poorly and dying are accounting for 4. 65% and 1. 60% of total individual number, respectively.
