摘 要:采用层次分析法(AHP)和专家评分相结合的方法,建立食用菌原料林优良树种筛选综合评价体系。评价体系包含4个Ⅰ级指标和12个Ⅱ级指标,12个Ⅱ级指标中以生产的食用菌品质P2(0.287 4)、采伐利用年限P7(0.187 3)、蓄积年平均生长量P8(0.187 3)、适用于食用菌生产P1(0.095 8)处于重要地位。利用评价体系,对初选的25科40属47种阔叶树种进行评价,其中综合评价指数≥2.400 0的16个树种,可作为贵州食用菌原料林的主要树种加以应用。其中,鹅掌楸、麻栎、桤木、光皮桦、褐毛杜英、山杜英、南酸枣7个树种应大力发展。综合评价指数在2.100 0≤Y<2.400 0之间的10个树种作为候选树种,综合评价指数<2.100 0的21个树种建议不用于食用菌生产。A comprehensive evaluation system, which focus on optimal selection of raw material forest species of edi- ble fungi, was established by combination of Analytic Hierarchy Process (AHP) and Experts Grading Method (EGM). The evaluation system is divided into two levels. The I grand indexes include 4 indices and the II grand indexes include 12 indices. The weighted value of production quality of edible fungui P2 (0. 287 4), usable time P7 (0. 187 3), annual average increment P8 (0. 187 3), edible fungui production suitability P1 (0. 095 8) are larger than other l/grand indices. Based on the comprehensive evaluation system, this study analyzed and screened 25 branches, 40 genera and 47 species broadleaf trees. There are 16 species broadleaf trees whose comprehensive assess- ment index is equal or greater than 2. 400 0. They are available as major tree species for edible fungi development of Guizhou Province, species such as Liriodendron chinense , Quercus acutissima, Alnus crenustogyne , Betula luminfera, Elaeocarpus duclouxii, Elaeocarpus sylvestris, Choerospondias axillaris in particularly. 10 species broadleaf trees with their comprehensive assessment index 2. 100 0 ≤ Y〈2. 400 0 were suggested as candidates. 21 species broad- leaf trees with their comprehensive assessment index less than 2. 100 0 were not suggested.
