| 摘 要： | 利用柞蚕蛾制作蜂卡,对大蚕蛾平腹小蜂林间寄生率调查。运用粗糙集方法赋权分析林分不同因子对大蚕蛾平腹小蜂寄生率的影响。结果表明:林龄、郁闭度、坡度等指标权重分别为0.263、0.368、0.368,算得均方根误差(RMSE)为1.081。由此分析认为,在林分因子中,林龄、郁闭度和坡度对平腹小蜂寄生率影响较大。并将粗糙集理论与特尔斐法进行了比较,其中均方根误差(RMSE)降低了2.172%,表明利用粗糙集方法适用于林间寄生效果的评价。

| Abstract: | The Antheraea pernyi egg cards were made for the parasitic rate survey of Anastatus sp. in forests and the parasitic situation was analyzed by using rough set method. The results showed that the weight of forest age, canopy density, slope index determined by the rough set method were 0.263, 0.368 and 0.368, respectively,with a RMSE of 1.081. Based on the analysis, the factors forest age, crown density and slope greatly influenced the parasitic rates of Anastatus sp. compared with the Delphi method, the root mean square error (RMSE) decreased by 2.172%,suggesting that the rough set method was suitable for parasitic rate survey in the forest. |
