摘　　要：对黑龙江省培育水曲柳混交林３种途径的可行性和主要经营问题进行了讨论。在人工混交林的培育途径中、立地条件的选择是培育成功与否的先决条件。在水曲柳与落叶松的人工混交林和人工、天然混交林中种间关系是森林经营首要考虑的问题。应用次生林天然演替规律及栽针、引针是天然混交培育途径的关键。研究认为，水曲柳与落叶松的混交林应以培育中小径级的落叶松、中大径级的水曲柳为培育目标。The paper discusses the possibility and main problem of three ways developing Manchurian ash mixed forest in Heilongjiang province. Selecting site is in the first condition in the way to develop Manchurian ash mixed plantation. The interspecific relationship .would be considered to the first problem of forest management for larch and Manchurian ash plantation or mixed forests.
