As floods and some other disasters broke out in 19th century, the Federal Forest Police Act came into force in 1920 in Switzerland, in which clear cutting in public forests and private protection forests was prohibited. In 1932 the clear cutting prohibition was extended to private forests. A sustainable and “close to nature” silviculture with natural regeneration and selection forest system were propagated in Switzerland influenced by Gayer (1882). In 1905 the Swiss forest Research Institute made 3 selection forest research plots for this reason. By 1931 a further 17 plots had been added in which three plots are still being surveyed today. According to this trend, the productivity and sustainability of forest had been studied, especially between clear-cutting in even-aged forest and single tree selection in uneven-aged forest. And the trend for transforming of even-aged to uneven-aged forests is well-known. Some countries forest administrations already strongly promote uneven-aged forests as leads to more stable forest stands. However, the forest management impact and comparison between even and uneven-aged forest under selection harvest method are often. This study is to illuminate the importance of forest management; to compare even and uneven-aged forest productivity and sustainability, and compare productivity among three different tree species: European larch, Norway spruce and Swiss stone pine; Analyze the parameters affect productivity and sustainability. The results show that the managed forest is more producible than unmanaged forest; the productivity of even-aged forests is higher than uneven-aged forests in Emmental, Switzerland.
