摘要
首先,通过效益监测获得大量资料,建立各种森林植被与生态因子的数学模型,为效益评价奠定基础。其次,构建官司河流域防护林林种结构优化配置评价体系。最后,利用层次分析方法,确定不同林种所占权重,从而得出其结构优化配置的依据,为防护林体系的经营管理提供理论指导。
A great mass of data were acquired by efficiency monitoring, the mathematical models on forest vegetation and ecological factors were established,which laid a foundation for benefit evaluation,shelterbelt forest kinds of structural optimization with the department of evaluation of Guansi River Basin were constructed.Total weight of different forest types were determined by analytic hierarchy,in order to obtain the basis of its structure optimization,which provided the theoretical guidance for operation management of protection forest system.
