     Results From 2005 to 2006, population density of the Gloydius shedaoensis Zhao was 0.0278 piece/m2. The peak terms of the movement of migratory birds and predation were in spring and autumn. The shrub forests were predation and habitation fundamental units of the Gloydius shedaoensis Zhao, which were 63.38% in population quantity, the scarce trees and grasslands were 27.04%, the arbor forests and bare lands were 5.86%、3.72%.

Results From 2005 to 2006, population density of the Gloydius shedaoensis Zhao was 0.0278 piece/m2. The peak terms of the movement of migratory birds and predation were in spring and autumn. The shrub forests were predation and habitation fundamental units of the Gloydius shedaoensis Zhao, which were 63.38% in population quantity, the scarce trees and grasslands were 27.04%, the arbor forests and bare lands were 5.86%、3.72%. Predation of the Gloydius shedaoensis Zhao lasted for the shortest time in spring and lasted for the longest time in autumn, the predatory rate was 10.92%、8.61%. Concluson It is very important to concern trends of the movement of migratory birds.

目的进一步了解蛇岛蝮蛇的种群动态,深入探讨全岛的种群密度和分布格局对捕食率的影响。方法结合蛇岛蝮蛇种群数量调查,对全岛所有区域的各种生境蝮蛇数量进行标记统计,每1~2天进行一个沟溪全面踏查,分别记录春秋两季不同区域、不同生境的蛇岛蝮蛇不同年龄组的分布数量和捕食状况,进行比较。结果2005~2006年蛇岛蝮蛇种群密度为0.0278条/m2,春秋两季是候鸟迁徙和捕食高峰时期,灌木林是蛇岛蝮蛇捕食栖息的主要场所,占全部种群的63.38%,其次是稀树草地27.04%,乔木林和裸地分别为5.86%、3.72%。蛇岛蝮蛇春季捕食持续时间短,捕食率10.92%,秋季捕食持续时间长,捕食率为8.61%。结论应密切关注候鸟迁徙的动态。
