摘要
位于广西东部珠江水系区的苍梧县珠江生态经济型防护林体系的优良造林树种选择研究,是根据树种的生物学、生态学特性,并以构成其防护林体系的防护林、用材林、经济林、薪炭林各林种的功能需求特征为依据,在充分遵循其树种优化选择原则的基础上,采用层次分析法对各林种功能作用所需求的要素,按其层次分解为不同的组成因素,并按因素间的相互联系、影响及其隶属关系进行组合,形成一个多层的分析结构模型,即树种优化选择的评价模型,用指标层相对于控制层(目标层)的重要性权重来确定营建该防护林体系待选的56个树种的优劣次序,明确了不同林种对其造林树种选择诸因素(依据)间的权重问题,评选出了适合苍梧县营造珠江生态经济型防护林体系的优良造林树种,为营建其最大综合效能的珠江生态经济型防护林体系的优良树种选择提供了科学依据。
We used an optimized evaluation model for the selection of 56 tree breeds, which were used in forestation along Zhujiang River in Cangwu county of Guangxi Province. The methodology was based on the trees＇ biological and ecological characteristics and its functions on the river banks. An analytic hierarchical process （AHP） was used for the elements the functions each stand needed, then we decomposed it into different layers of constituent factors. According to the conrrelation, effects and relationships belonged within the factors, a muhi-layer analytic model was formed. It thus was obtained the weights of importance from controlling layer with regard to index layers.
