摘要: 以生物多样性指数、马尾松毛虫虫口密度和成本投入作为指标,用灰色决策理论对不同放菌量和不同放菌频度的12种接种式放菌方案作局势决策,以确定最佳放菌方案。结果表明:放菌量为37.5g/hm2,放菌频度为一年一次的放菌方式最佳。

Abstract: With biodiversity, caterpillar population density and control cost as indices, optimal inoculating frequency and dosage were determined based on grey decision-making method. Result showed that the releasing dosage at 37.5g/hm2 and frequency at one release every year was optimal.
