摘　　要：对海南省澄迈林场的降香黄檀人工林展开病害调查,探讨营林措施对降香黄檀的叶部病害发生的影响。通过采用单因素方差分析和相关分析,结果表明:管理措施对降香黄檀的病害发生的影响达到极显著水平(F=41.654,P=0.000;F=31.509,P=0.001)。精细管理的林分的病害发生显著低于其他的管理方式的样地。孤立林分的发病率和病情指数都显著低于纯林、混交、套种等栽培模式。不同混交模式间发病率和病情指数存在显著的差异(F=24.358,P=0.000;F=13.145,P=0.000),其中,降香黄檀和檀香的混交林的发病率和病情指数最低。In order to explore effect of Silvicultural Measures of Dalbergia odorifera plantations on leaf diseases occurrence, this study carried out a field survey in Hainan Chengmai forest farm about Dalbergia odorifera leaf Diseases. One-way ANOVA, correlation analysis and other methods were used to analyze. The results showed that the disease incidence （DI） and disease severity index （DIS） among the different management level were significantly different（F=41.654, P=0.000; F=31.509, P=0.001）. The DI and DIS of fine management samples were significantly lower than those of other management methods. DI and DIS was significantly lower in insolated stand than in other three planting mode, pure stand, mixed stand, interplanting stand. The DI and DIS among the different mixed mode were significantly different （F=24.358, P=0.000; F=13.145, P=0.000）. DI and DIS was lowest in Dalbergia odorifera mixed with Santalum album stand than in other three mixed mode.
