In April, May, August, and October 2006, grid-based sampling method was adopted to investigate the diversity and abundance of arthropods on 50 islands in the Thousand-island Lake, with the effects of island area, island altitude, island shape, inter-island distance, and island-mainland distance on arthropod species richness analyzed. With the increase of island area, the richness of total arthropod species and that of the arthropod species with high- and low- dispersal ability all increased, and the relationships between island area and arthropod species richness corresponded to the classical island biogeography model. The island area, island altitude, and island shape had comprehensive effects on the arthropod species richness, while inter-island distance and island-mainland distance had less effects. The richness of total arthropod species had a significant positive correlation with island altitude and island shape, that of the arthropod species with high- dispersal ability was significantly positively correlated with island area and island altitude, while no significant relationship was observed between the richness of arthropod species with low-dispersal ability and the island characteristics.
2006年4月、5月、8月和10月，采用基于网格的采样方法对千岛湖50个岛屿上节肢动物的多样性和丰度进行了调查，并分析了岛屿面积、岛屿海拔、岛屿形状、岛屿间距离和岛屿与大陆距离对节肢动物物种丰富度的影响。随着岛屿面积的增加，节肢动物总物种丰富度以及具有高、低扩散能力的节肢动物物种丰富度均增加，岛屿面积与节肢动物物种丰富度之间的关系符合经典岛屿生物地理学模型。岛屿面积、岛屿海拔和岛屿形状对节肢动物物种丰富度有综合影响，而岛屿间距离和岛屿与大陆距离的影响较小。节肢动物总物种丰富度与岛屿海拔和岛屿形状呈显著正相关，具有高扩散能力的节肢动物物种丰富度与岛屿面积和岛屿海拔呈显著正相关，而具有低扩散能力的节肢动物物种丰富度与岛屿特征之间未观察到显著关系。
