本文运用系统工程原理,采用多目标、多因子的综合分析方法,从整体上研完了山区林业生产的系统开发利用问题。并以一个大队为实例,提出了以林为主,各业并举,以短养长,长短结合的合理的生产结构,建立了具体的数学模型,求出了优化解。结果表明,优化解不仅改变了林种、树种结构,提高了森林覆被率,而且使全大队以林为主体的收入从6.89万元,增加到了19.57万元,实现了生态效益与经济效益的统一,为山区发展林业提供了科学依据。

Taking the measures of the statistical methods of gradual regressive, etc., this paper has set up the multifactor linear equation between the bark quantity of acacia mearnsii De Wild in the main cultivated regions arid the factors in its site, by which the bark yield of the trees in different sites can be predicted. The paper points out that the fa ctors which influence the bark quantity are soil quality, the position and the shape of the slope, the depth of humus soil, and the content of organic matter....
