摘要
2008年5月汶川地震对两栖动物栖息地造成了巨大的影响。采用卫星遥感照片评估了汶川地震后3种两栖动物栖息地震损状况,结果表明:(1)15.2%的两栖动物的适宜栖息地遭到了地震的破坏;(2)震损栖息地纬向分布于31°～32°N之间,震区的南部和中部;(3)被破坏的栖息地垂直分布于2000m以下的中低海拔区段。汶川地震及次生灾害使两栖动物的生存和发展面临着极严重风险。
The amphibian habitat is impacted seriously by the Wenchuan earthquake. Three amphibians habitat was analyzed based on remote sensiong before and after the earthquake. The results showed that 15.2% of amphibian habitat was severely impacted. Most destroyed habitat centralized between latitude 31°～32°N which were in south and center areas. Furthermore, 100% of the destroyed habitat were distributed under 2000 m. The survival and flourish of amphibians were confronted with the strike of secondary disasters in the future.
