桓仁泡子沿废弃采石场刺槐客土造林初报

Afforestation of Acacia vulgaris with Alien Earth Soil along Paoziyan Abandoned Quarries in Huanren Region

针对桓仁地区20世纪70年代遗留下的泡子沿废弃采石场的地质环境问题,在多次生态修复失败后,2001年结合当地气候、立地条件及植物的生态适应性,试验尝试了客土营造刺槐林。经过15年生长已郁闭成林,取得了较好的造林效果。文章介绍了废弃采石场概况、树种选择及造林方法,并对不同坡段造林成活率、保存率进行了调查和分析。

Aiming at the geological environment problems along the abandoned quarries after the1970s in the Huanren Region,after several failed ecological restorations,afforestation experiments of Acacia vulgaris by using alien earth soil were conducted combined with the local climate,site conditions and the ecological adaptability of the plants in2001.Fortunately,it has created Acacia vulgaris forest.After15years of growth,it has been closed to forests and optimal afforestation results have been achieved.The general situation of abandoned quarries,selection of tree species and afforestation methods were introduced.The survival rate and conservation rate of afforestation at different slopes were investigated and analyzed.
