摘要
甘肃地处我国黄土高原、内蒙古高原与青藏高原的交汇处,是一个山地型高原,加之复杂的地貌、气候、土壤等因素的综合作用,植物种类丰富,数量庞大,苋科植物的分布较多.通过对甘肃苋科植物资源的考查以及对西北师范大学和兰州大学现有苋科标本所做的整理和鉴定,得出甘肃苋科植物有3属11种(包括3种栽培种),研究分析了其属种组成、生物学特征及经济价值,对其以后的开发利用及保护提出了一些建议.
Gansu is located in a crossing zone of Loess Plateau, Mongolia Plateau and Tibetan Plateau. Due to the complex topography and diverified soil and climate, a high number of plant species occur there. Three genera and eleven species （including 3 cultivative species） are found in Gansu. In this paper, the distribution and indentification of species in Amaranthaceae are investigated. The distribution, economical utilization and conservation of some species are further analysed and sumarized.
