一棵树值多少钱?那得看怎么算。砍了当柴禾烧,一把火,显然值不了几个钱。如果成材,出几方木料,还得看市场供需,自有定价。如果不砍,大树成荫,挡风遮雨,给人们带来无穷乐趣,那价值就难说了。“独木不成林”,一棵树的价值不好算,森林的价值就更难说了。多少年来,人们对森林的价值只有定性的分析,缺少定量的研究,从古至今,一本糊涂账。 How much is a tree worth? That depends on how to count. Cut firewood firewood, a fire, apparently worth a few money. If the timber, timber out several parties, have to look at the market supply and demand, its own pricing. If you do not cut, tree-lined, wind and rain, bring fun to people, that value hard to say. “Do not stand alone trees,” the value of a tree is not good, the value of the forest is even harder to say. For years, people have only a qualitative analysis of the value of forests, lack of quantitative research, from the ancient times, a muddleheaded account.
