We set up a Data Base with formulated time-series data which have been made by individual researchers without standardization. We formulated the time-series of meteorological data which were obtained in Lambir Hills National Park, Sarawak, Malaysia, and the data on plant phenology (flushing, flowering and fruiting) with ca.500 individuals of plants observed bimonthly and those'on insect catch by light-trap monthly during four years, to analyze the seasonality and periodicity by spectrum analysis, factor analysis and so on. Especially, we developed the protocol to determine the climatic factors to explain the fruiting and flowering phenomena. As the result, we discovered that the dry spell caused by El Nino Southern Oscillation can trigger the flowering of many trees in the dipterocarp forest in South-east Asia where no seasonal rainfall and fluctuation of temperature are detected.

我们建立了一个数据库，制定的时间序列数据已由个别研究人员没有标准化。我们制定了在马来西亚沙捞越州兰比尔山国家公园获得的气象数据的时间序列，以及植物物候学数据（开花、开花、结果），采用光谱分析、因子分析等方法，分析了4年中植物开花、开花、结果的季节性和周期性，特别是我们制定了一个协议，以确定气候因素来解释结果和开花现象。结果，我们发现厄尔尼诺南方涛动造成的干旱期可以触发东南亚没有季节性降雨和温度波动的龙脑香林中许多树木开花。
