对太行山闪长岩裸岩山地爆破整地造林作了效益分析,试区由原来的光秃砂石山变成满山的刺槐林,林草覆盖率由不足10%提高到70%以上,年平均土壤侵蚀模数由爆破前的1500t/km2·a降为500t/km2·a,开创了闪长岩山地爆破造林先例,取得了显著的生态效益、经济效益和社会效益。
Benefit analysis was made on blasting afforestation of bare rock in the Taihang Mountains. The trial area turned from bare bare rocky hill to mountainous locust. The coverage rate of forest and grass increased from less than 10% to more than 70%. The annual average soil The erosion modulus decreased from 1500t / km2 · a before blasting to 500t / km2 · a, which set a precedent for blasting and afforestation in mountainous area and achieved remarkable ecological, economic and social benefits.
