摘  要：
本文利用遥感数字图像与GIS空间分析和灰色关联度的分析方法,对全球最大的遗鸥迁徙栖息地红碱淖湿地2001~2011年间遗鸥种群繁殖数量与其生境敏感因子之间的耦合关系进行了分析。结果表明:2001~2011年间,保护区内遗鸥栖息的主要场所湿地面积与湖心岛面积逐年减小,这与遗鸥种群繁殖数量持续稳定增长呈负相关。对生态敏感因子进行分析可知,林地面积的增加以及沙地破碎度和草地破碎度的增加,改善了保护区内的生态景观和遗鸥的栖息环境,这些因子与遗鸥种群繁殖数量存在强关联度,是影响红碱淖遗鸥种群繁殖数量持续稳定增长的关键因子。遗鸥卵孵化率与水体面积、湖心岛面积、居民地破碎度、耕地面积存在高关联度,与保护区内人口增多,违法捕猎行为以及造成的周围环境变化密切相关。

摘  要：
This paper analyzed the coupling relationship between habitat sensitive factors and populations of relict gulls from2001 to 2011 in Hongjian Nur, the biggest migrate and habitat place all over the world, with remote sensing digital maps and the methods of GIS spatial analysis and grey correlation degree model. The results indicated there was a negative correlation between the decrease of the area of wetland and small islands in a lake year by year and the steady growth of populations of relict gulls. In terms of ecological sensitive factors, the improvement in the ecological landscape and the habitat environment were going with the increase of woodland area, sand fragmentation and the grass fragmentation. These factors had a strong correlation with the breeding number of relict gulls, they were crucial in influencing the steady growth of the breeding number of relict gulls. The hatchability of relict gulls strongly correlated with the area of small islands in a lake, resident fragmentation and farmland, it had a close relationship with the increased population in protection zone, the illegal hunting and the change of around environment, too.
