随着工业发展而带来的公害日趋严重以及人们生活水平的不断提高,人们对森林在卫生保健、疗养休息、美化环境、净化空气、消除噪音等方面的需要,将超过对木材的需要。现在,世界各国有越来越多的人,正研究森林在提供木材以外的其它方面的效益问题。苏联学者 B.M.多勒戈舍夫认为,森林既有作为原料资源的作用,又有作为非原料资源的作用。森林这两方面作用的经济效果,就是对森林资源的综合评价。为便于比较,对这两方面作用,应取同一的计量单位,即货币金额。
With the increasing pollution caused by industrial development and the continuous improvement of people’s living standard, the demand for wood in the fields of health care, rest and recuperation, landscaping, air purification and noise elimination will exceed the demand for wood. Now more and more people in all countries of the world are studying the benefits of forests in other aspects of providing timber. Soviet scholar B.M. Dorogorshe believes that forests have the role of both as raw material resources and as non-raw material resources. The economic effect of the two functions of the forest is the comprehensive evaluation of the forest resources. For the sake of comparison, the two units of measurement should be the same unit of measure, namely the monetary amount.
