植物物候模型研究

Study on Plant Phenological Model

植物物候模型是基于植物对环境因子的响应机理而建立的可模拟植物生长发育的数学方程。本文介绍了树木物候模型和作物物候模型,根据对植物休眠解除过程的不同理解,树木物候模型主要有7种不同的类型;根据作物发育规律而建立的作物物候模型也大体相同。同时,还阐述和探讨了研究植物物候模型的意义、研究中存在的问题及其发展趋势。

Plant phenological model is mathematics functions to simulate plants growth, which is based on the responses oi plant ongoing on environment factors. Tree and crop phenologieal models were introduced in this paper. According to different tmderstandings of plant dormancy released process, there are seven different types of tree phenologieal models. As for crop phenological models, there are generally the same crop phenological model, according to the growth and development rule of crops. The significance of plant phenological model study, the problems existed in the study and its development trends were discussed.
