摘要
应用软系统归纳集成法,确定了太行山主要针阔叶树种生态功能的评价指标体系与权重,其中一级评价指标5个,二级评价指标9个。利用大体一致的200多块样地的调查资料,对太行山广泛分布的针阔叶树种的生态功能进行了分类评价、优劣排序和聚类分析,将评定等级为优良的9种阔叶树和5种针叶树,作为农林复合生态系统建设中可广泛应用的树种,最后从海拔、坡向、年均降水量、气温、土壤等方面总结了优良针阔叶树种的适宜立地条件。
The evaluation index system and their weight of ecological function for coniferous and broadleaf tree on Taihang Mountain are put forward by using SSMII method, which includes 5 first-grade indexes and 9 second-grade indexes. After evaluation, listing and cluster analysis, there are 9 species of broadleaf and 6 species of coniferous tree selected out for using widely in ecological construction. The suitable site for them is also stated according to altitude, exposure, mean annual precipitation,average temperature and soil.
