摘　　要：为了解决人工防护林的衰退枯死问题,在调查研究的基础上,讨论分析了榆林沙地樟子松人工林衰退的原因,主要是由水分亏缺、土壤养分短缺及林分密度过大所致,在此基础上提出“林药间作”、“林草共植”,针阔混交、带状栽植的营林措施,为解决人工林衰退、提高人工林生态系统的稳定性、促进森林可持续经营技术与模式的形成提供理论参考。In order to solve the decline and death of artificial protection forest,this paper discusses the core problems of the decline of pinus camphoricus plantation in Yulin sandy land based on the investigation and research,which have been mainly caused by water deficit,soil nutrient shortage and high stand density.Then it puts forward the forest planting measures of“forest-medicinal herb intercropping”,“forest-grass interplanting”,mixed broadleaf-conifer planting,strip planting.It would provide theoretical guidance for solving the problem of plantation decline,improving the stability of plantation ecosystem,promoting the formation of sustainable management technology and model of forest.
