通过对不同的排矸年限矸石山的植被调查，结果显示：Ⅰ类排土场，随着排土年限增加，出现了多种植被群落，该生境的适生植物种类较多，具备了进行人工植被恢复的良好条件；Ⅱ类排土场，从群落外貌看，形成了明显的复层结构，群落的形成使排土场生境条件进一步改善，可进行人工复垦造林；Ⅲ类排土场仍处于演替的初级阶段，已初步具备耐旱乔木树种生长的条件；Ⅳ类排土场无植被分布，不适宜人工复垦造林，需经过多年的风化或人工促进风化进一步改善生态环境。%Vegetation of waste dump with different years of waste rock discharging was investigated.Result shows that:multiple vegetation communities appear in classⅠDump with increased age;the habitat have many species suit-able plants,which have a good condition of the artificial vegetation recovery;classⅡdump,from the appearance of the community,distinct stratified structure was formed composite layer structure.The formation of the dump fur-ther improves habitat conditions,and artificial reclamation afforestation can be conducted;class Ⅲ dump is still at an early stage of succession and has growth conditions for drought-tolerant tree species;class Ⅳ dump has no vegetation distribution and unfits artificial reclamation afforestation,it requires years of weathering or artificial weathering to promote further the ecological environment.
