摘　　要：食性研究是种群生态学研究的重要内容。当前鸟类的食性研究主要涉及以下几个方面:通过食物判断种间关系(Anderson,1978,Orians & Horn,1969),分析资源利用(Anderson,1978),结合食量研究生产力及能流(Pinowski,1968),研究食物对种群生育力及死亡率的影响(Anderson,1977;Pinowski,1968)等。我国学者在麻雀(Passer montanus)食性方面曾做了大量工作,报道了除青藏、云贵等地以外,几乎全国各地区的麻雀食性。Feeding ecology of the Tree Sparrow (Passer montanus) was studied in the field of Shunyi County, Beijing (40?69’N, 116?39’E) every year from April to October in 1980 and 1981. The stomach contents of 434 adults, 379 youngs and 483 nestlings and 225 samples of nestling crops were analysed. The main conclusions obtained are as follows: 1. The diet of both adult and young, analysed by dry weight, was comps-sed primarily of vegetable and grits throughout the breeding season. 2. The changes of sprrows’ diet were consistent with the period of crop maturation. 3. In May and June, the sparrow fed partly on the aphids, but there was no observable effect on the aphid’s number in the sample field of wheat. 4. The calorific value of the mixed food taken by nestling is about6.40 Kcal. gram-1, a nestling needs 39 gram (dry weight) of food, the majority of which is insect throughout the nestling period.
