天然次生林立体经营模式的研究

按照生态林业的基本思想和生态学的理论,以辽宁东部山区的天然次生林为对象,建立了森林立体经营模式,并对模式的结构与功能、模式建立后森林生态因子及林分因子的变化、各种经济植物的生长发育状况以及模式内主要经济动植物的人工管理措施等方面进行了调查和分析。结果表明,在天然次生林综合经营的同时,加入各种经济动植物成分,组建多物种、多层次的森林立体经营模式是可行的,它具有显著的经济、生态和社会效益。

STUDIES ON THREE-DIMENSIONAL MANAGEMENT PATTERN OF NATURAL SECONDARY FOREST

In this paper, taking the natural secondary forest in the east mountains of Liaoning as the object of study, three-dimensional management models of forest were established according to the basic ideas of ecological forestry and ecological theory. The aspects, such as structure and function of models, changes in forest ecological factors and stand factors after establishing these models, growth and development status of various economic plants,as well as the artificial manage want measures of main economic animals and plants in models, and so on, were investigated and analysed. The results indicated: it was possible to add in various economic components of animals and plants together with the comprehensive managements of natural secondary forest so as to establish threedimensional management models with multi-species and multi-stratum, which have prevailing ecological, economic and social benefit.
