利用鸟类评估生态工法成效之可行性探讨

Study of the Practicability by Use Birds To Estimate Effects of Ecological Engineering Methods

近年来 ,国际上风行所谓的“生态工法”(Ecological Engineering Methods) ,而台湾自 1997年起亦大力倡导 ,虽然有许多学者提出相关论述 ,但仍仅停留于技术发展阶段 ,致于如何其评估生态成效 ,则仍未触及。由于生态成效所涉猎的范围甚为广泛 ,如何评估实为一大课题。鸟类是一种对于环境相当敏感的族群 ,而且比较容易观测 ,因此许多研究常常以鸟类与环境的关系进行探讨。鸟类在生态上为较高级的消费者 ,因此当植物发生改变时 ,鸟类的数量与种类也随之改变。探讨鸟类做为评估生态工法成效之可行性 ,并应用穿越线法 (L ine transects)探讨中兴大学校园内不同植群对于鸟类栖息的影响。结果发现鸟类于不同植群时 ,其数量与类别有显著的差异。由观测的结果发现 ,鸟类的栖息与植群环境的关系密切 ,且许多文献均指出不同的鸟类其栖息环境均有差异 ,因此选择适当的指针鸟类 。

Ecological engineering methods were popular in international recently,and have promoted in Taiwan since 1997.Many researchers have revealed several related discussions and interpretations;however,ecological engineering methods are not put into practice in evaluating the effects of ecology.Ecological engineering methods are many aspects concerning,consequently,the issue of how to conduct the evaluation is crucial.Birds are very sensitive to the environment.Therefore,several studies are conducted which concerning the relationship between birds and environment.Birds are the higher consumers in the ecology.Consequently,when the vegetation changed,the birds' species and quantity are changed too.The study is based on many literature reviews and applied line transects to investigate the influences of vegetation categories on birds' habitation at the campus of Chung Hsing University.The finding of this study revealed that the birds' quantity and species are significantly affected by vegetation categories.Moreover,many literature reviews pointed out that certain bird's species has specific habitations.Consequently,the choice of proper bird species can be applied as an indicator to estimate the effects of ecological engineering methods.
