摘要
带、网、片是半干旱风沙区防护林体系基本组成单元。从林带、林网及片林3个方面依据一定原则对体系建设质量提出了15个评价指标,建立防护林建设质量评价指标体系。采用层次分析法确定了各个指标对于目标层的权重值,从而形成了可量化的防护林体系质量评价指标,为半干旱区防护林体系生态功能评价提供了新思路。
Belt, net and slabbing is basic components of protection forest system in semi-arid area. About 15 quality evaluation indexes on system construction quality were formed by forest belt, forest net and forest flake base on common principle, and the quality evaluation index system was established for protection forest construction. Weight values of various indicators of the target layer were determined by layer analysis method, thus a quantifiable quality evaluation index system of protection forest system was formed to provide new ideas for ecological evaluation of protection forest system in semi-arid region.
