摘要：

Douglas-fir (DF) performance was investigated in mixed plantations across a range of forest site conditions in the Czech Republic. DF showed both comparable and superior capability to perform well within transect from lowland natural-pine to higher and mountainous sites. DF root collar diameter increment exceeded all other native species such as Norway spruce (NS), silver fir (NSF), sessile oak (OK) and European beech (BE). Higher to mountainous conditions favored the native species compared to DF. Mortality of DF ranged 5-53% over investigated period; the only exception was the site where DF was attacked by large pine weevil and showed mortality 54-97%. Generally, DF showed comparable or even lower mortality compared to the native species.
