Researches on leaf phenology of forest trees and related subjects were carried Out On Mt.Kinabalu, Sabah Parks, Sabah, Borneo Island, Malaysia from 1996 to 1998. Leaf phenology involves timing of leaf appearance and leaf fall, leaf emergence pattern, leaf longevity and evergreenness and deciduousness. In a preliminary simulation, we first predicted that all trees on this mountain is evergreen but leaf longevity is either shorter or longer than 1 year. These predictions were revealed to be true by the researches carried out in the mountaneous forests. Evergreen trees which have shorter leaf longevity than 1 year were, for example, Rubus lineatus on high altitude, Macaranga rostrata and Ficus spp. on mid altitude and Macarangagigantea and M.hypoleucain low altitude. Flush and successive leaf emergence patterns were observed. Tree species which showed flush pattern were for example, Neolitsea spp, Rhododendron spp, Castanopsis spp, Quercus spp, Eugeneaspp, and tree species whish showed successive leafing were Macarangaspp, Rubus spp and others. Timing of leaf emergence within a year was various among species. Many trees were observed to emerge their leaves during a period of moderate drought around March.

1996 ~ 1998年在马来西亚婆罗洲岛沙巴沙巴公园的京那巴鲁山进行了林木叶物候及相关学科的研究。叶的物候学包括叶的出现和落叶的时间，叶的出现模式，叶的寿命和常绿和落叶。在初步的模拟中，我们首先预测这座山上的所有树木都是万年青的，但叶子的寿命要么短于1年，要么长于1年。在山地森林中进行的研究表明，这些预测是正确的。叶寿命短于1年的万年青树木有高海拔的悬钩子、长喙血桐和榕树等。在中海拔，Macarangagigantea和M.hypoleucain低海拔。冲洗和连续的叶片出现模式进行了观察。表现出齐平型的树种有新木姜子属、杜鹃属、锥属、栎属、丁香属等，表现出连续型的树种有玛卡林属、悬钩子属等。一年内出现的叶的时间是不同的物种。在三月左右的一段中度干旱期间，观察到许多树木长出了叶子。
