【摘要】 通过对20世纪80年代营造的针阔混交林生物量调查表明,红松阔叶混交林生物量比红松纯林高4.9%~21%,落叶松阔叶混交林生物量比落叶松纯林高7.6%~21.3%,红松阔叶混交林单株生物量比红松纯林高120%~148%,落叶松阔叶混交林单株生物量比落叶松纯林高108%~151%,在不同混交林型中,灌木层和草本层植物种类丰富、数量多,所以其生物量大于纯林。更多还原

【Abstract】 Investigations on biomass of mixed coniferous & broadleaved trees cultivated in Eighties in the 20th century shows that : biomass of Pinus koraiensis broadleaved mixed forest is 4.9%-21% higher than that of Pinus koraiensis pure forest;biomass of broadleaved mixed forest of larch is 7.6%-21.3% higher than that of pure forest of larch;per plant biomass of Pinus koraiensis broadleaved mixed forest is 120%-148% higher than that of pure forest of Pinus koraiensis;biomass of broadleaved mixed pure forest of larch per plant is 108%-151% higher than that of pure forest of larch;among different mixed-types,species of plant is rich and quantity of plant is large in shrub & herb layer,so their biomass are greater than that of pure forest.更多还原
