森林所生产的木材和其它林副产品是工农业生产和人民生活必不可少的重要物资,而森林在涵养水源、保持水土、调节气候以及改善自然环境等方面的效益远比木材生产的经济价值大。可是过去我们只习惯于算木材收益账,不算生态效益账,这样做影响了人们对林业建设的全面认识,是不合理的,今后不应再延续下去了。 Wood and other forest by-products produced by forests are important supplies for industrial and agricultural production and people’s livelihood, while the benefits of forests in conserving water, maintaining soil and water, regulating climate and improving the natural environment are far greater than the economic value of timber production . However, in the past, we only used to calculating timber revenue and not eco-efficiency accounts. This has affected people’s overall understanding of forestry construction and is unreasonable and should not be continued in the future.
