For conservation planning of the regional ecosystems based on relationship analysis between landscape factor and species diversity

利用已发表的北海道地区鸟类和植物分布的资料，提出了几个简单的指数，并绘制了生物多样性指数图。利用这些数据，我们分析了与土地利用和地形等景观因素的关系，并确定了生物多样性保护的重要领域。通过对湿地生态系统物种多样性的分析，阐明了指标组合在湿地生态系统物种多样性评价中的重要性。并通过景观结构变化和GAP分析提出了区域生态系统保护的要点。

Several simple indexes were proposed and mapped to represent biodiversity by using the information available from previously published data for the distribution of birds and plants in Hokkaido region. We analyzed the relations with landscape factors such as landuse and topography using these data and identified important areas for biodiversity conservation. We clarified that combination of the indexes was important for species diversity evaluation from analysis in wetland ecosystems. And the outline for the regional ecosystem conservation through the change of the landscape structure and GAP analysis were proposed.
