摘　　要：以4年生新伐毛竹为试材,以白腐菌彩绒革盖菌为试菌,对壳聚糖铜配合物(CCC)、壳聚糖锌配合物(CZC)及相应的金属盐(氯化锌)和铜铬硼(CCB)处理材的抗流失性和耐腐性能进行试验。结果表明:壳聚糖金属配合物在竹材中固着率略高于CCB,明显高于相应的金属盐,具有较强的抗流失性能;CCC处理的竹材对彩绒革盖菌的耐腐性能高于CCB处理材,当CCC处理材中金属离子保持量达到6·35kg·m-3时,腐朽后质量损失为0;CZC处理毛竹试材的耐腐效果和CCC效果相当,明显高于氯化锌处理材,当防腐剂中金属离子保持量高于2·41kg·m-3时,CZC处理的竹材都达到最耐腐等级,且随着防腐剂中金属离子保持量的提高,处理材的质量损失率接近于0。The leachability and decay resistance of 4-year-old bamboo wood treated with chitosan copper/zinc complexes （CCC and CZC） were reported in this paper. Results showed as follows： 1） To chitosan-metal complexes（CCC and CZC）, the amount of metal ion fixed in bamboo wood was slightly higher than CCB, while significantly higher than the corresponding metal salt. 2） The decay resistance of CCC against Coriolous versicolor was better than CCB. When the metal ion retention in bamboo wood reached 6.35 kg·m^-3 , mass loss of the treated bamboo wood was 0 percent. 3） The decay resistance of CZC against Coriolous versicolor was nearly equivalent to that of CCC, and remarkably better than that of only treated by relevant metal salts. When the metal ion retention in bamboo wood exceeded 2.41 kg·m^-3, mass loss of the treated bamboo wood tended to be 0 percent.
