一、芬兰的情况:1.芬兰在从前择伐(所谓大径木择伐和小径木择伐)所占的比重较大。但目前因感觉到这种森林作业法不好,所以改用其它种采伐方式。2.皆伐作业的比例急速增加,据第三次国有林调查,森林主伐中50%是皆伐。国有林主要采用皆伐方式,私有林一般采用天然更新方式。3.芬兰的树种不适于培育复层林,故不采用择伐,最近几年来由 First, the situation in Finland: 1. In Finland, the proportion of pre-harvesting in the past (the so-called large-diameter wood selective cutting and small-footprint wood selection) accounted for a large proportion. However, due to the fact that such a forest operation law is not good, it has switched to other harvesting methods. 2. The proportion of clear-cut operations has increased rapidly. According to the third state-owned forest survey, 50% of the total amount of forest clearance is clear-cut. The state-owned forest mainly adopts the method of clear cutting, and the privately-owned forest generally adopts the natural way of updating. 3. Finland’s tree species is not suitable for the cultivation of stratified forest, it does not use selective cutting, in recent years by
