Abstract: This article discusses the influence of intermediate cuttings on growth in height, growth in thickness, forest yield, maturity and locality according to the 13 years' test of intermediate cuttings conducted in larch plantation. The results showed that through the resonable intermediate cuttings, the height increment was increased by 19—57%, the diameter increment was increased by 30—104%; the mature age was shortened to 20—25 years; the economic benefit was raised by 50—100%. The test also proved that intermediate cuttings could not heighten the forest yield during the same cutting.
