摘  要:
拉姆萨尔国际重要湿地作为野生濒危动物的栖息、繁衍或越冬场所,承载着湿地生物多样性保护的重要功能。本文在300、600和1200 km 3个尺度上,利用空间自回归模型,对国际重要湿地濒危物种丰富度的影响因素进行了研究。结果表明,在解释拉姆萨尔国际重要湿地濒危物种丰富度的若干假说中,人类干扰假说具有最高的解释率,其次为能量假说和生境异质性假说。国际重要湿地濒危物种丰富度的主要影响因子是气温年较差、生境规模以及人均国内生产总值(GDP),气温年较差和生境规模与国际重要湿地濒危物种丰富度显著正相关,人均GDP与其呈显著负相关。本研究有助于在全球尺度上深入理解湿地濒危物种丰富度的成因,对于湿地濒危物种的保护具有现实意义。

摘  要:
Ramsar Wetlands of International Importance are significant for biodiversity protection as roosting,breeding or wintering sites of endangered species. The driving factors of wetland endangered species richness were analyzed by using the spatial autoregressive model at the scale of300,600 and 1200 km. The results indicated that human interruption hypothesis has the highest explanatory strength among all hypotheses for endangered species richness of Ramsar sites,followed by energy hypothesis and habitat heterogeneity hypothesis. The endangered species richness of Ramsar sites is significantly positively correlated with annual range of temperature and habitat size function,and significantly negatively correlated with GDP per capita. The results are helpful to deeply understanding the driving factors of endangered species richness on global scale as well as to endangered species protection of global Ramsar sites.
