摘    要:利用 5月份温带草原鸟类繁殖期 ,在荒漠草原、草原、湿地、沙地和山地等植被 ,选取 1 1个面积 1 0 0 hm2 ( 50 0 m×2 0 0 0 m)同样大小的样区 ,由 3人各隔 1 50 m作平行的穿越线调查 ,并记录所见鸟类的种类与数量。同时 ,也在每一样区任取面积 1 m2 之植被样方 ,记载样方内植物的种类、垂直高度、覆盖度和植物鲜重。调查结果显示草原繁殖鸟类的种类不多 ,在无树的荒漠草原植被是 4~ 6种 ,草原植被在 5~ 8种之间 ,湿地植被 1 5种 ;在有树的沙地植被是 9~ 1 2种 ,山地植被 6种。鸟种多样性和丰富度指数不大 ,由大而小依序是沙地植被、湿地植被、山地植被、草原植被、荒漠草原植被 ;密度也不高 ,由大而小依序是无树草原的湿地植被、草原植被、荒漠草原植被 ,而后是有树草原的沙地植被、山地植被。鸟类食性分布方面 ,荒漠草原和草原植被以食杂性鸟类为优势 ;湿地植被以食虫性鸟类为多 ;沙地植被以食杂与食肉性鸟类为胜 ;山地植被以食虫和食杂性鸟类较多 ,并增加一些食肉性鸟类。

关 键 词:荒漠草原植被  繁殖鸟类群聚  鸟种多样性  丰富度

Abstract:A census of breeding birds was carried out in the vegetation of steppe, typical grassland, wet grassland, sand grassland, and mountain forest grassland in May, 1998 in the temperate steppe of Inner Mongolia, China. Eleven 100 hm 2 plots with three transect lines , each 150m apart, were studied. Meanwhile, 1m 2 of vegetation within each plot was used for recording plant species, vertical height, coverage, and weight.As the results indicated, the numbers of species of breeding birds in the grasslands of Inner Mongolia were low. There were 4~6 species in steppe, 5~8 species in typical grassland, 15 species in wet grassland, 9~12 species in sand grassland, and 6 species in mountain forest grassland. Bird species diversity and richness index were also low. In descending order were sand grassland, wet grassland, mountain forest grassland, typical grassland, and steppe. Bird densities in order from large to small were wet grassland, typical grassland, steppe, sand grassland, and mountain forest grassland. As for the food habit distributions of breeding birds, in the steppe and typical grassland omnivores were dominant, in the wet grassland insectivores were dominant, in the sand grassland omnivores and carnivores were dominant, and in the mountain forest grassland insectivores and omnivores, followed by carnivores were dominant.
Keywords:steppe  typical grassland  wet grassland  sand grassland  mountain forest grassland  breeding bird community  bird species diversity  and richness
