摘    要:确定了小叶锦鸡儿、中间锦鸡儿和柠条锦鸡儿3种植物的分布式样:小叶锦鸡儿为蒙古高原东部-F松辽平原西部-华北山地分布种,中间锦鸡儿为东戈壁-鄂尔多斯高原-黄土高原北部分布种,柠条锦鸡儿为南阿拉善-西鄂尔多斯分布种。小叶锦鸡儿适应分布于蒙古高原典型草原带和森林草原带以及华北山地落叶阔叶林带,在草原带高平原上可形成灌丛化草原的景观,在草原带的沙地上可形成以小叶锦鸡儿为建群种的沙地灌丛植被;中间锦鸡儿适应分布于蒙古高原的荒漠化草原及草原化荒漠带、鄂尔多斯高原的典型草原和荒漠化草原带的沙地及梁地上、黄土高原北部的黄土丘坡上,常形成以中间锦鸡儿为建群种的沙地灌丛植被;柠条锦鸡儿则适应分布于草原化荒漠和典型荒漠带的固定和半固定沙地上。近缘的3种锦鸡儿的地带性分布从东至西或从北向南形成明显的有规律的地理替代分布格局。

关 键 词:锦鸡儿属  小叶锦鸡儿  中间锦鸡儿  柠条锦鸡儿  分布式样  地理替代分布  生态适应。

Abstract:The distribution pattern of Caragana microphylla,C.davazamcii and C.korshinskii was revealed.C.micraphylla is a distribution species of the eastern Mongolia Plateau-the western Songliao Plain-the mountain of North China,C.davazamcii is a distribution species of the eastern Gobi-the Ordos Plateau-the northern Loess Plateau,C.korshinskii is a distribution species of the southern Alashan-the western Ordos.C.microphylla distributes over the typical steppe zone and the forest stepe zone of Mongolia Plateau and mountainous deciduous broad-leaved forest zone of the North China.On the high plain of steppe zone,C.microphylla may forms the shrub steppe landscape,on the sand land of steppe zone it is a dominant species of shrub vegetation.C.davazamcii distributes over the steppe desert zone and the desert steppe zone,the sand land and hill of the Ordos Plateau,and Loess hill of the northern Loess Plateau.C.davzancii is also a dominant species of shrub vegetation.C.korshinskii distributes over the fixed and semi-fixed dune of the steppe desert and the typical desert zone.The zonal distribution of above 3 kindred plants of Caragana forms a obviously geographic substituted distribution from east to west or from north to south.
Keywords:Caragana  C  microphylla  C  davazamcii  C  korshinskii  distribution pattern  geographic substituted distribution  ecological adaptation
