摘要
浙西山区雉类栖息地的植被类型、分布高度存在差异,其主要活动地有季节性变化,并和月降水量相关。黄腹角雉在浙江西部分布于金衢盆地以南,白颈长尾雉、白鹇和勺鸡在浙西山区均有分布。对该山区秋季和春季的雉类密度进行调查,秋季捕获率以勺鸡最高(4.58‰),白颈长尾雉次之(1.42‰),白鹇最低(0.39‰)。春季遇见率勺鸡为0.15只/小时,白鹇为0.175只/小时,白颈长尾雉仅0.063只/小时。白颈长尾雉和白鹇存在正关联的种间关系,而其他雉类间不存在关联。植被群落的演替可导致雉类群落的变化,主要表现在雉类的种类组成和数量的波动等几方面。70年代至80年代浙西雉类资源持续下降。
A survey of the rare pheasants was conducted in the western areas of Zhejiang Province. The habitat of different pheasants seemed to have its own vegetation type and altitude in these areas. Seasonal veriations of main habitat of the pheasants were observed. The altitude and monthly rainfall of the habitat had a remarkable relatedness. Tragopan caboti was distributed in the area south to Jin-qu Basin. However, Syrmaticus ellioti, Lophura nycthemera and Pucrasia macrolopha were all found in the mountainous areas of western Zhejiang. In autumn, the capture rate of Pucrasia macrolopha was the highest (4.5‰); next Syrmaticus ellioti(1.42‰); Lophura nycthemera was the lowest (0.39‰). In spring, the relative density of Pucrasia macrolopha was 0.15 ind/hr, Lophura nycthemera 0.175 ind/hr and Syrmaticus ellioti 0.063 ind/hr. A positive relatedness between Syrmaticus ellioti and Lophura nycihemera may exist, but there was no relatedness among the other pheasants. According to the observation, it seems that the succession of the plant community results in the changes in the community of the pheasants, mainly in its specific composition and density. The number of pheasants in the west of Zhejiang is decreasing in 1970s and 1980s.
