摘　　要：落叶松为华北地区高山针叶林带中的主要森林树种。随着我国经济的快速发展,对木材的需求量加大,落叶松人工林种植面积持续增加。目前,由于其林分结构不合理、林分密度过大,出现了林地土壤肥力持续下降,并引起了林木生长量的下降等问题。本文综述了目前我国落叶松人工林土壤肥力的研究现状及改善措施,并指出一是通过自然干预可以大大减少人力及财力的消耗,二是进行科学合理的造林经营管理,可以防止土壤肥力下降,这可为落叶松造林可持续发展提供有力支撑。Larix gmelinii is a main forest species in the alpine coniferous forest belt in North China.With the rapid economic development in China,the demand for wood is increasing,and the planting area of larch plantation has increased constantly.At present,due to the unreasonable stand structure and high stand density,the soil fertility of forest land has been declining continuously,and the forest growth has been reduced.In this paper,the research status and improvement measures of soil fertility of larch plantation in China were reviewed.The paper also points out that the human and financial consumption can be greatly reduced through natural intervention,and the scientific and reasonable afforestation management can prevent the decline of soil fertility,which can provide a strong support for the sustainable development of larch afforestation.
