对洛斯巴诺斯、拉古纳和卡勒兰退化林地的马卡岭森林速生树种进行了研究，分析了这些树种在各个地区的特征和生产力。对退化土地的适应能力最强的树种是金合欢，其次是木通。在土壤物理性质得到改善的地方，也门表现出良好的生长。叶曼和柚木是耐火树种，其生长逐渐改善。金合欢林下龙脑香科苗木的年生长量为30~40 cm，有的高达4m以上，相思林凋落物达1500 g/m~2以上。这一数值几乎是洛斯巴诺斯长期轮换森林树种的两倍。学科：林业和林产品附加关键词：速生树种、长轮作、人工林、林下种植
Fast-growing tree species planted in the Makiling forest in Los Banos, Laguna and degraded forest land in Carranglan were examined to analyze the characteristics and productivity of these tree species in each area. Acacia auriculiformis was found to be the most adapted species to degraded land, followed by yemane (Gmelina arborea). Yemane showed excellent growth where the physical soil properties were improved. Yemane and teak (Tectona grandis) were fire-tolerant species and their growth gradually improved. Annual height increment ofDipterocarpaceae seedlings planted under A. auriculiformis ranged from 30 to 40 cm and the height of some of them exceeded 4 m. Litter on the Acacia forests amounted to more than 1,500 g/m2. The values were almost twice those of tree species for long-rotation forests in Los Banos.
