Indeks Kualitas Tempat Tumbuh Tegakan Bambang Lanang di Sumatera Selatan (Site Index of Bambang Lanang Stand in South Sumatra)

Site index is indispensable in the management of plantation forests, including bambang lanang ( Magnolia champaca ) community forest which has long been cultivated as timber-producing trees South Sumatera Province. This research aimed to produce a site model stands developed on small-scale private forests Sumatra. was by phytocentric and geocentric methods respectively using dominant height characteristic data from 22 permanent sample plots spread over various development areas lowland highland. Based methods, stand were expressed four (Ho) equation Ln Ho = 3.1033-3.2406(1/A ), 3.2658-3.2406(1/A), 3.4055-3.2406(1/A) 3.5282-3.2406(1/A) for 17 m, 20 23 26 m. Furthermore, classified into five classes sites I, II, III, IV, V with range <17 17-20 20-23 23-26 >26 Meanwhile, based Bambang Lanang Si -6.709-0.010 altitude + 5.255 pH (KCl)+ 0,171 clay percentage 0,184 solum 1.070 Al saturation 7.698 total N.
