一、何谓速生丰产林速生丰产林国外叫高产林、丰产林,是一个产量概念;我国速生丰产林是复合概念:速生是指树种特性,是一个速度概念,指在同一时间内立木材积增值速度较其他树种快,成材年限相对短;丰产是产量概念,指在同一时间内单位面积产量较其他树种高。丰产是速生的结果,速生是丰产的条件。

First, what is fast-growing and high-yielding forest Fast growing and high-yielding forest Abroad called high-yield forest, high yield forest, is a yield concept; fast-growing forest in China is a complex concept: fast-growing refers to the species characteristics is a concept of speed refers to the value of timber at the same time It is faster than other tree species and has a relatively short timber age. High yield is the concept of yield, meaning that the yield per unit area is higher than other species at the same time. High yield is the result of fast-growing, fast-growing is the condition of high yield.
