摘要
运用面积转换矩阵和景观指数对双台河口自然保护区丹顶鹤繁殖生境的变化进行分析。结果表明 ,该地区丹顶鹤繁殖生境的面积不断减小 ,景观异质性和破碎化程度不断增强 ,生境质量不断下降。生境质量的变化将直接引起在该地区丹顶鹤繁殖数量的变化 ,从 1989～1998年 ,在双台河口自然保护区繁殖的丹顶鹤数量逐年下降 ,丹顶鹤的繁殖容量日益减小 ,原因是道路和油井开发强度的不断增大等人类活动的影响。
Using area transition matrix and landscape indices,the change of red-crowned crane (Grus japonensis) breeding habitat in Shuangtaihekou National Nature Reserve was analized.The results showed that the area of red-crowned cranes breeding habitat was reduced while the heterogeneity and the fragmentation was increased.The change of the habitat quality can directly cause the change of the number breeding of red-crowned cranes.The number of breeding red-crowned crane in Shuangtaihekou National Nature Reserve was reduced from 1989 to 1998,mainly due to the activity of human beings,such as road construcition and oil drilling.
