几种乡土树种在采矿迹地植被修复中的应用

Application of Several Native Tree Species in Vegetation Restoration of Mining Sites

以波罗栎、滇青冈、高山栲、华山松、旱冬瓜、云南松等6个常见乡土树种为试材,通过对应用于采矿迹地植被修复造林初期成活率、保存率和生长量的追踪监测,探究乡土树种应用于采矿迹地植被修复中的可行性,结果表明:6种乡土树种应用于采矿迹地植被修复均能取得较高的成活率和保存率,但植被修复前期生长情况表现各异,其中旱冬瓜、云南松、高山栲在矿山迹地植被修复初期生长迅速,能快速成林,取得较好的植被恢复效果,可在今后的采矿区植被恢复中推广应用;华山松、滇青冈、波罗栎在采矿迹地植被修复中应用的可行性有待结合造林中、后期的表现进一步论证。

Taking six common native tree species as experimental materials,including Quercus acutissima,Cyclobalanopsis yunnanensis,Castanopsis kawakamii,Pinus armandii,Alnus nepalensis and Pinus yunnanensis,the feasibility of applying native tree species to vegetation restoration in mining areas was explored by tracking and monitoring survival rates,preservation rates and growth in the early stage of vegetation restoration and afforestation in mining areas.The results showed that the 6 native tree species could obtain high survival rates and preservation rates,but there were differences among species for growth in the early stages of restoration.Alnus nepalensis,P.yunnanensis and C.fargesii grew rapidly in the initial stage of vegetation restoration and provided better vegetation restoration effects,and thus these could be popularized in future vegetation restoration on mining areas.Meanwhile,the feasibility of the application of P.armandii,C.yunnanensis and Q.paniculata need to be further demonstrated in combination with the mid-and late-stage performance of afforestation.
