摘要
1994年 8～ 10月和 1995年 11～ 12月 ,采用直接测定法 ,对浙江西部开化县小北垅、水坞和严村山区的白颈长尾雉 (Syrmaticusellioti)栖息地片断化现状进行调查 ,提出了片断化程度指数 (F)与运算公式 ,并采用该指数对白颈长尾雉栖息地片断化程度进行测定与分析。栖息地的片断化与丧失将导致白颈长尾雉栖息地面积的减少。
During Aug. Oct.1994 and Nov Dec.1995,the studies on the fragmentation of habitats used by Elliot's pheasant were done in Shuiwu,Xiaobeilong and Yancun of Kaihua County,western Zhejiang with field observation and measurement.The index of the fragmentation ( F ) and its formula were produced in this paper.The fragmentation of the habitats,used by Elliot's pheasant was measured with this index.The results showed that the habitat fragmentation and loss would cause the loss of habitats used by Elliot's pheasant.
