摘  要：
1985—1987年,浙北龙山林场松、栎混交林大山雀繁殖种群的年平均密度为每公顷0.85对,明显高于纯马尾松林的0.57对(t=3.50,P<0.05)。1987年招引区的平均密度为每公顷1.48对,分别比同期混交林和纯林内的密度高2.6倍和3.4倍。通过分析大山雀的繁殖生物学,雏鸟食物中松毛虫比率并结合松毛虫种群密度变化,估计在松毛虫种群密度高的年份,大山雀对越冬后松毛虫幼虫的捕食作用约为0.29％,而在松毛虫种群密度低的年份,捕食作用则增加11.24倍,招引区内捕食作用增加29.19倍。

摘  要：
The duration of breeding season, nestling food composition and predation of nestling periods of great tit on the larvae of Dendrolimus punctatus were studied in 1985-1987 at Longshan Forest Farm, Anji County, Zhejiang Province (30°50'N, 19°42'E).The breeding season of great tit began in mid-March and ended in late-August. The duration of breeding season lasted about 152 days in 1987. There were three noticeable periods of laying start and hatching start in the clutches. The nestling periods were consistent with the periods of large larvae after overwintering, small and large larvae of first generation respectively.The mean breeding density of great tit in 1985-1987 in pine-oak mixed stands was higher than those in pure pine stands. The mean breeding density of great tit in 1987 in the stands with nestboxes were 2.6 and 3.4 times more than those in pine-oak mixed stands and pure pine stands at the same period.While in the year of larvae density was higher, about 183, 250 larvae per ha, the predation of nestling period of great tit on the larvae was only 0.21%. The predation can increase by 11.24 and 29.19 times in the stands of no nestboxes and with nestboxes when the larvae density was lower, about 6 032 larvae per ha.
