为了更好地摸清东源县古树资源情况,推进古树建档工作,更好地保护古树,本研究对河源市东源县15个镇的古树进行了实地和走访调查,结果显示:东源县15个镇共有古树738株,隶属于30科42属54种。树种以红锥为主(248株),其次为榕树、木荷、朴树、樟等。古树树龄大多数为III级古树(661株),18株I级古树,59株II级古树;树高平均为16.98 m,胸径最大的为榕树,达467.92 cm,平均为96.51 cm,冠幅平均为264.35 m2。大多数古树均正常生长,仅有少数衰弱。根据调查结果,建议加快东源县古树建档工作,加强管理和保护,对于生长环境不好的古树,改善其周边环境,并定期开展病虫害防治。 |

Most of them are Castanopsis hystrix (248), then Ficus microcarpa, Schima superba, Celtis sinensis, Cinnamomum camphora. The individual number is 661, 56 and 18 with tree age of 100-299 a, 300-499 a and more than 500 a, respectively. The average of height is 16.98 m; average of diameter at breast height is 96.51 cm, with the top 1 is Ficus microcarpa (467.92 cm) and the average of crown area is 264.35 m2.
