摘要
本文通过对辽东地区落叶松人工林连我与土壤水分、容重、孔隙度等物理性质及林木生长关系的研究，认为落叶松人工林连栽地力衰退的原因之一是土壤物理性质恶化所致。
In this paper, the relations between larch plantations of continuous cropping and soil water, volume weight, porosity, tree growth and other soil physical properties were studied. The results showed that the important reason for site degradation of larch plantations of continuous cropping was due to the deteriorated physical properties of soil.
