摘　　要：通过对承德铜矿、铁矿、银矿3种尾矿库栽植的沙棘生长状况进行研究发现,沙棘对土壤的要求不严格,不覆土成活率可达到60%,覆土可以达到95%以上。3种尾矿沙都严重缺氮,沙棘本身具有固氮作用,能增加尾矿沙中氮的含量。种植在覆土铜矿、铁矿、银矿尾矿沙上的沙棘,株高年均增长量、地径年均增长量以及根长年均增长量铁矿最大,铜矿次之,银矿最小。因此,沙棘是尾矿库绿化的优良先锋树种。Through studying on the growth status of Buckthorn in copper, iron and silver tailings dam in Chende. It showed that the Buckthorn did not require high on soil. The Buekthorn＇ s survival rate up to 60% without soil and over 95% with soil. Three kinds of tailings sand were lack of nitrogen seriously, the nitrogen fixation of Buckthorn can improve the nitrogen content of railings sand. The Buckthorn planted on the three kinds of tailings sand with soil, the iron railings dam had the biggest annual average increment of plant height, ground diameter and root length. The copper railings dam took the second place, and the silver tailings dam was the minimum. In hence, the Buckthorn can be used as the excellent pioneer species in greening tailings dam.
