丹顶鹤越冬栖息地数学模型的建立

A wintering habitat model for red crown crane.

利用地理信息系统及遥感卫片通过建立数学模型的方法来模拟及预测盐城自然保护区丹顶鹤越冬栖息地的分布 .经验证 ,模型的正确预测率为 72 6 3 % ,认为模型基本上能够反映丹顶鹤栖息地的分布情况 .

A mathematical model was established based on GIS and RS to simulate and predict the habitat distribution of red crown crane( Grus japonensis ) in Yancheng Biosphere Reserve,Jiangsu Province,China.The model was tested through calculating the match coefficience of observed and predicted presence/absence data,which was 72\^63%,showing that the model could be used to reflect the habitat distribution of red crown crane.
