摘要: 人工培育起来的异龄复层阔叶红松林,1—10年间每公顷年蓄积净生长量为2.90m3,生物量年净生长量为4.1t,年投资为35.26元。比同龄人工红松纯林蓄积量高3倍,生物量净生长量高0.7倍,投资额降低63.1%。异龄复层阔叶红松林,垂直结构合理,能充分利用光能,调节温度,贮水能力强,林下土壤疏松,肥沃,容重小,通气透水性强,有利于有机物质分解。

Abstract: Man-made forests of uneven-aged and irregular spaced broad leaved tree-Korean pine has been studied for years. The forest is rational at vertical structure. Sun light energy is fully utilized, inside it with the effect of temperature regulation. The forest has a strong water holding capability. The soil of the forest land is loose and fertile, the bulk density of the soil being rather light. Both the aeration and water permeability of the forest soil has been improved, with the helpful result for resolving organism.The average increment in growing stock in the man-made forest of uneven-aged and irrgular spaced was 2.9m2/ha·a during 10 years, increased 3 times as against even-aged pure Korean pine forest, while the increment of biomass was 4.1t/ha.a, 0.7% increased. The sum of investment, however, was only 35.26 Yuan/ha·a, which is 63% less as compared with that for pure Korean pine forest.
