城市绿化树种多样性对鸟类的影响

The Effect of Urban Greening Tree Species on Bird Diversity

随着城市化的加剧,自然环境的破坏,对居住在城市中的鸟类产生了很大的影响。为更好地保护城市鸟类的多样性,给园林绿化提供基础材料,于2006年9月至2008年7月对牡丹江城市绿化树种进行了详细的调查,记录树种共63种,并就树种多样性对鸟类的影响进行了调查,共记录鸟类91种,隶属14目31科,占全国鸟类总数的7.69%,在居留型上,主要以夏候鸟为主。区系组成以古北种为主,找出了树种多样性与鸟类之间的关系。多数鸟类的繁殖分布与树冠盖度密切相关;对于部分在灌丛中繁殖的鸟类,灌丛盖度是决定其繁殖分布的主要因子。因此,园林绿化增加植被的盖度有助于鸟类在城市中繁殖和定居。

Increasing urbanization and destroying natural environment have had a great effect on bird diversity. In order to protect urban bird diversity,in order to provide fundamental material for city landscaping. A investigation on urban greening tree species in the city of Mudanjiang was conducted in detail from September 2006 to July 2008 ,Totally 63 tree spcies were recorded. And an investigation was on the effect of tree species diversity on bird diversity was also conducted. Totally 91 species in China were recorded. The study showed that summer resident was the majority in residentee and the fauna component was dominated by palaearetic species. The relationship between species diversity and bird diversity was also found out. Reproductive distributed of mose of the bird was closely related with crown cover degree. For the birds partly distrbuted in shrub, shrub coverage was the main factor which determined reproductive distribution. Increasng vegetation coverage, therefore, is beneficial for bird reproduction and residing in cities.
