摘要
2000年在广东茂名郊区油页岩废渣场上引种30多种阔叶树种,经过5年生长后,不同树种林下植被自然入侵情况有明显的不同,以翅荚决明林下植被的种类最丰富,覆盖率最高,海南红豆、海南蒲桃、土沉香等树种林下植被的覆盖率也很高,是理想的矿山迹地植被恢复树种。同时,也总结出林下植物入侵的先锋种为飞机草、日本草、牛筋草等。
Move than 30 broad-leaved tree species had been planted on the shale dump in Maoming city.After 5 years＇ growing, the invasive vegetation of every species has a big difference. Cassia alata forest is the best one with the most sufficient vegetation under the trees and also with the highest eoverage. And Ormosia pinnata,Syzygium Cumini and Aquilaria sinensis, with high coverage, also are the best species for the vegetation restoration on shale dump. In addition, the dominant species under the trees are Eupatorium odoratum and Eleusine indica,etc.
