求翻译：现国内外都在寻找各种技术对尾矿坝进行综合治理，国内恢复植被传统的技术是在尾矿表面覆盖厚度达30-50cm的土壤，再种植抗旱、防护植物，但是此方法不仅浪费大量的人力、财力，还受水源、土壤等因素的影响，植物的成活率低，达不到理想的效果。火炬树根系发达，根蘖萌发能力强，耐寒、耐旱、耐盐碱、适应性强、极易繁殖，在酸性、中性及石灰性土壤以及瘠薄干燥的沙砾土上均能生长。利用火炬树对尾矿坝进行植被的覆盖，不仅可以提高植物的成活率，还减少大量的人力和财力的投入。是什么意思？

Presently domestic and foreign all is seeking each kind of technology to carry on the comprehensive program of public order to the debris dam, the home restores the vegetation tradition the technology is reaches 30-50cm in the debris surface cover thickness the soil, again plants the drought-resista

Tailings dams at home and abroad are looking for a variety of techniques to be a comprehensive way, internally restored traditional technique in tailings surface vegetation cover thickness of 30-50cm of soil, plant drought-resistant, protective plants, but this method not only wastes a lot of effort
