水土保持优良植物——牧场草在黄土高原地区的引种适宜性评价

Evaluation of the adaptability of Bromus biebersteinii,a fine grass species for soil & water conservation introduced from USA to the Loess Plateau

由美国引进的水土保持优良植物———牧场草 ,在黄土高原大部分地区种植后 ,适应性较强。结合气候相似法、模糊综合评判法以及引种栽培试验 ,得出牧场草的适生中心区位于黄土高原的北温带部分 ,呈一条东北 -西南走向的非常宽阔的带 ,包括黄土高原沟壑区、丘陵沟壑区所有副区、风沙区等类型。

In the most parts of the Loess Plateau, Bromus biebersteinii ,a fine grass species for soil and water conservation introduced from USA had very good adaptability. By means of meteorological similarity, comprehensive fuzzy evaluation and experiment of introduction, the most suitable areas were determined,which located in a wide range region from southwest to northeast in the north temperate zone of the Loess Plateau, including the sub-region such as tableland, gully, hill and sandy areas.
