Abstract

Post-coal mining areas need rehabilitation to restore its functionality. Not all plants could grow well on bare ex-coal mining area because of the excessive light intensity and extreme temperature fluctuations. This study is aimed to determine suitable local tree species for rehabilitating mined areas. Planting was carried out in November 2012, and observations were made in November 2015. The study site was in the district of Samboja, Kutai Kartanegara, East Kalimantan Province, Indonesia. Research results revealed that seven tree species survived well in the ex-coal mining land, i.e., Vitex pinnata L., Syzygium scortechinii (Merr.) Merr. & Perry, Syzygium polyanthum (Wight) Walp., Shorea balangeran (Korth.) Burck, Macaranga motleyana (Mull.Arg.) Mull.Arg., Cleistanthus myrianthus (Hassk.) Kurz and Syzygium lineatum (DC.) Merr. & L.M. Perry. From the seven species V. pinnata, Sy. scortechinii and Sy. polyanthum performed best in both survival and growth rates. This study suggests those three species are excellent local tree species for ex-coal mining rehabilitation, not only because of their high survival rate (≥80%) and fast-growing but also they produce favourable fruits and flowers for wildlife.

加里曼丹东部采煤后地区当地树种的生长

后煤矿开采区需要修复以恢复其功能。由于光照强度过大和温度波动过大，并不是所有的植物都能在裸露的非煤矿区生长良好。本研究旨在确定适合修复雷区的当地树种。种植于2012年11月进行，观测于2015年11月完成。研究地点位于印度尼西亚东加里曼丹省Kutai Kartanegara的Samboja区。研究结果表明，在废弃的煤矿用地上，有7种树种存活良好，分别是：羽状葡萄、黄颡树和Perry，Syzygium polyanthum（怀特）沃尔普。，Shorea balangeran（Korth.）Burck、Macaranga motleyana（Mull.Arg.）Mull.Arg、Cleistanthus myranthus（Hassk.）Kurz和Syzygium lineatum（DC.）Merr.&L.M.佩里。在7个品种中，黄颡鱼和多珊瑚在成活率和生长率方面表现最好。这项研究表明，这三个物种是当地优秀的煤矿恢复树种，不仅因为它们的高存活率（≥80%）和快速生长，而且它们为野生动物开出了有利的果实和花朵。
