你了解森林有哪些效益吗?一般地说,森林的直接效益,即生产木材和用在燃料上的效益,是人们时时处处看得见、摸得着的,连懂事的小孩都知道它价值之大。但对间接效益,即生态效益和社会效益,却未必人人都知道得那么清楚。实际上,森林的间接效益远远大于直接效益,美国有人研究,认为直接效益和间接效益的价值之比是一比九。即森林间接效益的价值比直接效益大八倍。 Do you understand the benefits of forests? Generally speaking, the immediate benefits of forests, that is, the benefits of wood and fuel, are visible and tangible to people everywhere, and even children who are sensible know its value Big. However, indirect benefits, that is, ecological benefits and social benefits, may not all be known to everyone. In fact, the indirect benefits of forests are far greater than direct benefits. Someone in the United States has studied that the ratio of direct benefits to indirect benefits is one to nine. That is, the value of indirect forest benefits is eight times greater than direct benefits.
