通过对马占相思（Ａｃａｃｉａｍａｎｇｉｕｍ）人工林木材的天然耐腐性、耐久性、浸注性的测定和木材防腐试验，结果表明：（１）马占相思人工林木材由木腐菌彩绒革盖菌（Ｃｏｒｉｏｌｕｓｖｅｒｉｃｏｌｏｒ）和棉腐卧孔菌（Ｐｏｒｉａｐｌａｃｅｎｔａ）引起的失重率分别为３６６２％和３５７４％，属不耐腐级至稍耐腐级，野外耐久年限少于２年，属不耐久等级。（２）短周期马占相思人工林木材可方便地采用常温常压浸泡法、热冷槽法或半定量法进行防腐处理。用浓度３％的ＣＣＢ、ＴＷＰ或ＢＵ处理的试样，其耐腐性可从稍耐腐级、不耐腐级提高到强耐腐级。
The results showed that: (1) Acacia mangium plantation wood was composed of wood rot fungus cover Coriolusvericolor and Poriaplacenta were 3662% and 3574% respectively, which ranged from non-resistant to slightly decay resistant, and the endurance in field was less than 2 years Durable grade. (2) The short-period Acacia mangium plantation wood can be conveniently treated with the soaking method at room temperature and atmospheric pressure, hot chilled tank method or semi-quantitative method. With 3% concentration of CCB, TWP or BU treated specimens, the decay resistance can be slightly decay resistance, non-corrosion resistance grade to a strong decay resistance.
