栖息地演变与人为干扰对升金湖越冬水鸟的影响

2002年10月—2003年4月,选择安徽升金湖6个不同干扰程度和栖息地质量的固定监测点,研究人为干扰对升金湖越冬水鸟分布格局的影响;同时结合前期调查数据,研究栖息地演变对升金湖越冬水鸟的影响.结果表明:同一越冬期不同监测点水鸟种类和数量与栖息地质量无显著相关关系,但水鸟数量与栖息地干扰程度显著负相关;不同年份升金湖越冬水鸟种类和数量与栖息地质量显著相关.升金湖越冬水鸟存在的主要威胁包括栖息地丧失、人为活动干扰以及生物杀灭剂的影响.提出了一些保护升金湖越冬水鸟的建议.

Impact of habitat evolvement and human disturbance on wintering water birds in Shengjin Lake of Anhui Province, China

From October 2002 to April 2003, investigations were made at six monitoring sites with different degrees of human disturbance and habitat quality in Shengjin Lake to understand the impact of human disturbance and habitat evolvement on the distribution patterns of wintering water birds. The results showed that in the same wintering period, the species richness and population size of water birds at different sites had no significant correlation with habitat quality but significantly negatively correlated with human disturbance degree, while in different years, these two parameters were strongly correlated to habitat quality. The major threats to the water birds in Shengjin Lake were habitat loss, human disturbance and biocides, in light of which, corresponding protection measures were put forward.
