摘要: 为充分利用森林的可再生性和可培育性,最大限度地提升森林供给能力,从较宏观的角度评价了区域森林生产力。分析认为:森林生产力级数包括现实森林生产力级数和期望森林生产力级数,采用森林蓄积、森林每公顷平均蓄积量、森林生长量、木材产量4项因子计算。通过对我国现实和期望森林生产力的分析得知,我国的现实森林生产力已经下降到一个比较低的水平,恢复和提高我国森林生产力是一项刻不容缓的任务。从现实森林生产力出发,以期望森林生产力为目标,提出了提高森林生产力的途径,以保证森林资源效益的全面发挥。

Abstract: Base on the previous studies, the forest productivity is evaluated on macroscopic so that forest supply ability can be enhanced to the most advanced extent though forest rebirth and cultivation. The grade of forest productivity including actuality and expectation is computed according to forest amount, forest average amount per hectare, the growth quantity and the timber output. Through the study on the grade of forest actual and expect productivity, the result indicated that the grade of forest actual productivity in China is at low level, so resuming and increasing the forest productivity in China is an urgent demand. Starting with the forest actual productivity and aiming to the forest expect productivity, the approaches on improving forest productivity are put forward for the purpose that the benefit of forest resources can be in full function.
