大连岩质海岸黑松蒙古栎混交林土壤物理性质研究

摘要

通过对黑松蒙古栎林土壤物理性质的研究，评价了其水土保持效果。结果显示：混交林的土壤物理性质比纯林有显著的改善。从水土保持角度考虑，采用营林技术措施提高人工林和次生林混交度，能防止水土流失和地力衰退，为森林可持续经营提供依据。%Effect of water and soil conservation was evaluated through the study of soil physical properties of the mixed forest of Pinus thunbergii and Quercus mongolica .Result shows that soil physical properties have significant improve than than of pure forest .From the viewpoint of soil and water conservation,increasing the mixture of mixed plantation and secondary forest by adopting silviculture measures can prevent soil erosion and soil fertility decline , and provide the basis for sustainable forest management.
