摘要
随州曾都区现有银杏古树1 443株,树龄低于400年的占绝大多数,一、二、三级古树数量的比例为1∶2.10∶16.51。雄株特别少,且受人为破坏严重。银杏古树形态各异,具有很高的观赏价值,是当地一道特殊的景观或标志,管理养护粗放,亟待加强。本研究从加强管护和病虫害防治等角度提出了初步建议。
There are 1443 ancient Ginkgo trees in Zengdu district of Suizhou, most of which are at the age of 400 years old. The ratio of the number of trees of grade one to grade two to grade three is 1.00 : 2.10 :16.51. The female individuals are much more than the males, revealing that the ancient Ginkgo trees suf- fered serious artificial destruction. Ginkgo has so various shape and high ornamental value that it becomes special landscapes or landmarks in local areas. But the level of management is still very low to improve. The authors put forward suggestions in perspective of administration, disease and pest control.
