武汉市城区古树后续资源调查与分析

Investigation and Analysis on Resource Succeeding Ancient Tree in Wuhan City Zone

摘要:

经调查发现:武汉市城区古树后续资源有890株,分属30科47属61种,其优势种类与城区现有的古树优势种类相近,相同树种有樟树、珊瑚朴、朴树、桂花、女贞、银杏、枫杨、榔榆、三角枫、悬铃木等10个,但其乡土树种所占的数量比例下降明显;这些古树后续资源主要集中分布在武昌区,尤其是在东湖一带,在其它城区的古树后续资源分布十分零散。武汉市城区古树后续资源的生长状况总体上生长良好,但遭受白蚁的危害较为严重,占其数量比例的15·2%,有必要开展古树后续资源的白蚁防治工作。

Abstract:

According to this research, there were 890 succeeding ancient trees in Wuhan City zone and they were belong to 30 family, 47 genus and 61 species through inrestigation. There were similar dominant species between succeeding ancient trees and existing ones. The same species were Cinnamomum camphora (L.) Presl, Celtis julianae, Celtis sinensis Pers., Osmanthus fragrans (Thunb.) lour, Ligustrum lucidum Ait., Ginkgo biloba L., Pterocarya stenoptera A.DC, Ulmus parvifolia Jacq., Acer buergerianum Miq. and Platanus acerifolia Ait etc. Cuu the amount proportion of local trees declined obviously. The succeeding ancient trees were mainly distributed in Wuchang District, especially in the area of Donghu Lake. The distribution was scattered in other city zone. Generally they grew well. But the damage from termite was serious. Termite harmed about 15.2 percent of the succeeding ancient trees. So it is necessary to develop prevention work about termite of succeeding ancient trees.
