间伐强度对辽东落叶松人工林土壤理化性质的影响
Effects of thinning intensity on soil physicochemical properties of Larix kaempferi plantation in eastern Liaoning Province
摘要
Abstract
The present study investigated the response of soil physical and chemical properties of the larch (Larix kaempferi) plantation to thinning intensity after five years in eastern mountainous area of Liaoning Province,through collecting soil sample from the topsoil (0-10 cm) and subsoil (10-20 cm) along a thinning gradient (CK,20％,30％ and 40％).The results indicated that there were no significant variations in the soil bulk density,total porosity,capillary porosity,total C content,total N content,C ∶ N,N ∶ P,and NO3--N content under different thinning intensities,compared to the CK treatment.However,the soil water-holding capacity,total C content,total N content,N ∶ P,and active carbon content in the topsoil (0-10 cm) under the 40％ thinning intensity were significantly higher than under the other two thinning intensities.Furthermore,40％ thinning intensity was beneficial to obtaining the large-diameter wood.Therefore,the 40％ thinning intensity was preferable to the management of the larch plantations in the eastern mountainous area of Liaoning Province.关键词
