太行山区是我国华北典型半干旱地带,尤其低山石灰岩地区,土壤水分条件更差。近百年来,由于人口发展迅速,垦荒放牧,山场破坏严重,生态失去平衡。解放后,虽多次造林,但其成效甚微。经济林发展更慢,原有果木树已呈现干梢秃顶,日渐衰退。为了迅速改变这一地区穷困落后面貌,要首先发展经济林,从1985年冬季开始进行 Taihang Mountain is a typical semi-arid zone in North China, especially in low-mountain limestone areas, with worse soil moisture conditions. In the past century, due to the rapid population development, reclamation and pasture grazing, the destruction of mountain fields is serious and the ecology is out of balance.
