本文是根据三年的调查研究(共调查了约1000块标准地)和造试验林所取得的材料写成的。研究了油松林、栎林、刺槐林、灌丛和杨树林等的更新、造林以及经营方面的技术和营林体系问题。提出了在不能修筑窄带梯田发展干鲜果树的地段,提高森林覆盖率和林地生产力的育林措施。在林种搭配和营林体系选择方面,应因地制宜地采用封山育松栎林,营造刺槐薪炭林和小径材用材林,进行栎类播种造林和封养灌木林等。这是适应低山丘陵生态条件、经济有效的恢复森林植被的综合措施。
This article is based on a three-year survey (a total of about 1000 criteria) and material from a pilot plantation. Studied the problems of regeneration, afforestation and management of technical and silviculture systems in Pinus tabulaeformis, Quercus acutissima, Robinia pseudoacacia, shrubs and poplar forests. Proposed in the narrow terrace can not be built dry fresh fruit trees in the area, improve forest coverage and forest productivity of afforestation measures. In the aspect of forest type selection and silviculture system selection, afforestation of afforestation oak forest should be adopted according to local conditions to create firewood forest and small-diameter timber forest of acacia, and oak sowing afforestation and shrub-shrub forest shall be carried out. This is a comprehensive and cost-effective restoration of forest vegetation that adapts to the ecological conditions of low hills.
