In the first year of the project, we considered the framework of the new model to describe leaf longevity, leaf habit and leaf phenology. We adopted phenology model of Harada and Takada (1988), and leaf longevity model by Kikuzawa (1991). By combining these models we proposed a new model to describe leaf longevity and leaf habit in the world. In the second year of the project, we constructed several submodels describing photosynthesis-temperature relationships, decline in photosynthesis with time and changes in mean monthly temperature within a year. We also determined parameter sets and ranges of each of the parameter values and conducted actual calculations after some trial and errors. We obtained bimodal distribution of evergreenness across latitudes. We also observed evergreen and deciduous habits in seasonal environments together with evergreen habit in aseasonal environment. These results were presented in a symposium on leaf phenology in 8^<th> International Ecology Meeting held in Seoul. Also we are now preparing a paper to submit the result for the international journal.

在项目的第一年，我们考虑了新模型的框架来描述叶片寿命、叶片习性和叶片物候。采用原田和高田（1988）的物候模型和菊泽（1991）的叶片寿命模型。将这些模型结合起来，我们提出了一个描述世界上叶片寿命和叶片习性的新模型。在项目的第二年，我们构建了几个子模型来描述光合作用-温度关系、光合作用随时间的下降以及一年内月平均温度的变化。我们还确定了每个参数值的参数集和取值范围，并经过一些尝试和错误进行了实际计算。我们得到了各纬度常绿度的双峰分布。我们还观察了季节环境中的常绿习性和落叶习性，以及季节环境中的常绿习性。这些研究结果发表在2008年汉城国际生态学会议的叶片物候学研讨会上。此外，我们正在准备一篇论文，将结果提交给国际期刊。
