| 摘 要： | 本文通过实地观察和分析，指出冷蒿主要分布于典型草原中、西部和荒漠草原的东部。冷蒿大量出现是在轻度和中度退化草地以及强烈侵蚀地段上。芽的大量产生于根颈和近地面老枝基部；枝条接触土壤易产生不定根，草地退化后，冷蒿以不定根取代主根作用，成为群落的主体。冷蒿可分为斜奇型和直立型二种生态型，以斜奇型的冷蒿分布面积最广。生物产量随着群落组成种类，地上部分变化较大；地下生物量集中于土壤上层（０～２５ｃｍ土层），占总产量８９．０７％，其中以０～５ｃｍ土壤中占４２．７６％。

| Abstract: | Through field investigation that Artemisia frigida mainly distributes in the middle and west parts of typical steppe and the east part of desert sieppe was indicated.The large numeber of Artemisia frigida occurred in the light and middle deteriorated grassland and serious eroded land. Artenisia frigida bud is produced from coallar and the base of old branch which is near ground.The shoot which touched soil produced adventitious root,and the adventitious root replaced main in the deteriorated grassland.There are two ecotypes of Artemisia frigida ,erect and lean types and the lean type distributed widely.The aboveground biomass of Artemisia frigida varied and below ground biomass mainly distributed in the upper soil layer. |
