| 摘 要： | 针对太行山花岗片麻岩低山丘陵区水土流失严重,生态环境恶化的现状,通过对草木樨,紫花芷蓿,挲相旺与刺槐的不同搭配与种植方式的研究,发现刺槐与草木樨混种结构,尽管在造林初期林木的存活率及年生长量稍低,但在造林后４ａ的累计经济效益最高,可大大缩短造林成本的回收期,为一良好的林草立体种植结构。

| Abstract: | Due to serious natural problem cautal by water bo and sol erosion, this paper deals with sweet clover, alfalfa, erect milkvetch mixed with locust in granite - gneiss fowr mountain - hill of Taihang Mountain. The results showed that the total economic results within 4 years after planting was the highest for the sweet clover mixed with locus structure, although the survival rate, tree height and basal diameter of this structure was lowr. And the planting cost can be arered in a short period, so the grass glade which sweet clover mixed with locus is the bo way for stereo planting structure in the area. |
