一、引言造林设计是林业建设的先行和基础,是科学造林和管理的依据。成功的造林设计方案,不仅要遵循适地适树的自然法则,而且要遵循经济法则。这样才能合理利用林地,最大限度挖掘林地生产力,充分发挥人工林的生产效益,获得良好的经济效果。前人对此作了大量研究,取得重要成果。尹泰龙1978年用线性规划方法编制了适地适树方案,以便在已知林地面积条件下,寻找各种不同林分类型在不同立地类型上分别裁植多
I. INTRODUCTION Afforestation design is the forerunner and foundation of forestry construction and is the basis for afforestation and management of science. Successful reforestation designs must not only follow the natural law of the tree, but also follow economic rules. Only in this way can the rational use of forest land, maximum exploitation of forest productivity, give full play to the production of plantation benefits, access to good economic results. The predecessors made a lot of research and achieved important results. YIN Tailong prepared a plan for suitable tree planting in 1978 by means of linear programming, in order to find out different types of tree stand types in different types of stands under the known conditions of woodland area
