摘　　要：1997年5月,从澳大利亚引进21个山地木麻黄地理种源,在东山赤山国有防护林场沿海沙地上开展了种源试验,结果表明:以各种源材积、树高和胸径为评判指标,筛选出4号、7号、11号和13号种源为山地木麻黄优良地理种源,其树高增益均在12%以上,胸径增益均在11%以上,材积增益在30%以上。另外,具有较高胸径增益和材积增益的15号和16号种源也入选为优良山地木麻黄种源。Experlments on 21 provenances of Casuarina junghuhniana,which were introduced from Australia in 1997, were conducted on coastal sandy land in Dongshanchishan National Protection Forest Farm of Fujian province. The result indicates that ： taking for volume, tree height, DBH of different provenances as evaluating indices, No. 4,7,11,13--whose tree height, DBH,volume gain are all above 12%, 11% and 30%--are selected to be superior geographical provenances for Casuarina junghuhniana. In addition, No. 15,16, which have higher gain of DBH and volume, are selected too.
