摘　　要：2010—2012年,对甘肃省文冠果人工林的发展历程、人工林资源的数量、分布和生长状况进行了调查研究。结果表明:甘肃省文冠果人工林发展经历了两个阶段,即20世纪60—80年代和2008年到现在;栽培范围涉及全省14个市(州)的10个市(庆阳、平凉、天水、陇南、定西、白银、兰州、武威、张掖和酒泉);人工林资源量达2.18万hm2,其中约2.67 hm2是20世纪60—80年代栽培的,主要分布在甘肃中部和河西地区,多呈块状或散生分布;其余是2008年以后栽植的,涉及以上除酒泉、陇南以外的8个市,主要栽植在退耕地中,其次是农耕地和荒山;农耕地中的文冠果生长最好,其次是退耕地,荒山和低洼地的生长差。In 2010 - 2012, the investigation was conducted on development history, quantity, distribution and growth conditions of artificial plantation resources of Xanthoceras sorbifolia Bunge in Gansu prov- ince. The results showed that X. sorbifolia artificial plantation underwent 2 development stages in Gansu, namely between 60s and 80s of the 20th century and between the years of 2008 and 2012 of the 21st cen- tury. Its planted area included 10 cities （ Qingyang, Pingliang, Tianshui, Longnan, Dingxi, Baiyin, Lanzhou ,Wuwei, Zhangye ,Jiuquan）of 14 municipalities（prefectures） in Gansu province. The amount of artificial plantation resources reached more than 2. 18 x 104hm2. Among them,more than 2. 67 hm2 was the resources planted between 60＇ s and 80＇ s of the 20th century, which are mainly distributed in central area and Hexi area of Gansu, and now grow well. The remaining part of the resources was planted in the years between 2008 and 2012, mainly planted in returned farmland, cropland and wasteland, its cultivat- ed areas included 8 cities above except for Jiuquan and Longnan. In terms of the growth conditions, the seedlings planted in cropland are growing best, followed by those planted in those planted in returned farmland and those planted in wasteland and lowland are worse.
