植物物候对气候变化的响应

植物物候的变化可以直观地反映某些气候变化,尤其是气候变暖.植物生长节律的变化引起植物与环境关系的改变.生态系统的物质循环（如水和碳的循环）等过程将随物候而改变.不同种类植物物候对气候变化的响应的差异,会使植物间和动植物间的竞争与依赖关系也发生深刻的变化.目前欧洲、美洲、亚洲等许多地区均有关于春季植物物候提前,秋季物候推迟,使植物的生长季延长,从而提示气候变暖的趋势.植物物候的模拟模型构成生态系统生产力模型的重要部分.

Responses of plant phenology to climatic change

Changes in plant phenology directly manifests the change of climate, especially climate warming. The changes in rhythm of plant growth may alter plant-environment relationships, hence the mass cycles, such as water and carbon, in the ecosystem. Individual plant species respond to climatic changes differently, which may cause great changes in competition and dependence among different species and plant-animal interactions. In the past few years, many reports showed that the plant phonology toward early in spring and late in autumn in Europe, America, and Asia. The changes in plant phenology result in a lengthening growing season, and indicate a warming climate. Phenological model is an important component of ecosystem productivity models, which may play a key role in analysis of vegetation-atmosphere interactions.
