摘　　要：为了科学规划文冠果生物质能源林建设和合理开发现有文冠果野生资源,于2010—2012年,采用访问调查和实地调查相结合的方法,对甘肃省野生文冠果资源的分布、数量、生长状况、开发利用状况以及资源利用存在的问题进行了调查研究。结果表明,甘肃省属于我国文冠果的次集中分布区,野生文冠果总体呈零星分布,少量呈块状或片状分布;分布范围包括全省14个市(州)的5市2自治州,具体为该省东部的庆阳市和平凉市,南部的天水市、陇南市和甘南藏族自治州,中部的定西市和临夏回族自治州;资源的利用仅限于采种育苗和造林;存在的问题是资源分布零散、部分资源结实能力差,达不到资源开发利用的目的。In 2010 - 2012,the investigation was conducted on quantity,distribution,growth condition,exploitation ＆ utilization,and existed problems of wild resources of Xanthoceras sorbifolia Bunge in Gansuprovince. The results showed that Gansu province belongs to the second concentrated distribution area ofX. sorbifolia in China. The general distribution of wild X. sorbifolia was sporadic distribution in Gansu,but the small resources were clustered distribution or lamellar distribution. The distribution range included 5 cities and 2 autonomous prefectures of 14 cities （ prefectures）in Gansu province,i. e.,2 cities ofQingyang and Pingliang in eastern Gansu,2 cities of Tianshui and Longnan and 1 Tibetan Autonomousprefecture of Gannan in southern Gansu,1 city of Dingxi and 1 Hui Autonomous prefecture of Linxia incentral Gansu. The utilization of X. sorbifolia wild resources is only seed for breeding and forestation.Now the problems in resources utilization are sporadic distribution of whole resources and low fruit - bearing of some resources,which is far from the aim of developing and utilizing the wild resource of X. sorbifolia.
