摘要
本文应用地理信息系统，分析了朱（Ｎｉｐｐｏｎｉａｎｉｐｐｏｎ）栖息地洋县的地形、植被、水域和人为干扰的地理特征，根据朱的喜好将这４种景观因子对朱的适宜度进行量化，并把这４个图层叠加，得到栖息地对朱的综合适宜度。对比朱的实际分布，发现朱集中分布在适宜度较高的区域内，由此证明这４种景观因子对朱的重要性。另外，在部分高适宜度区域内从未发现朱，所以可能有其它因素影响朱的分布。
The habitat quality of the Crested
ibis was evaluated. First, we digitized the topographic map, vegetation map, river map, road
map, and village map by geographical information system, and gave each map the suitability
values according to the favorite degree of the Crested ibis. Then we overlaid these maps to
obtain an integrated map of habitat quality. Compared with the actural distribution of the Crested
ibis, we found that it always inhabited at the sites of high quality. This indicated that the factors
we chose were very important for the Crested ibis. However, we also found that the Crested
ibis never inhabited at some sites of high quality. We speculated, therefore, some other factors
restricted the distribution of the Crested ibis.
