摘　　要：森林生产力是评价森林生长的重要指标,但以往的研究主要是以林木实际生长量进行测定,没有考虑环境因素对其生长潜力的制约,本文就环境对林木生长潜力在数量上进行了探讨。结果表明:森林最大生产量和木材最大生产量的数值受气象条件的影响不大,而实际森林生产量和木材生产量却受到气象条件的限制,达不到最大值。Forest productivity is an important index to evaluate the forest growth condition.But the former research measured by the real growth yield,which didn＇t consider the environmental factors also can interact the growth potentiality.This article is to inquire to the environmental factors＇ influence in quantity.The result showed that,the forest maximum growth yield and the wood maximum growth yield were not affected by the weather conditions,however,the real forest yield and wood yield were not reached the maximum which were due to the weather conditions.
