花期物候对气候变化的响应进展

Flowering Phenology Response to Climate Change

由于人类活动引起大气温室气体增加造成气候变暖,温度的变化改变了大气水热时空分布格局,这不但引起植物花期物候变化,而且会改变植物花期与虫媒昆虫和病虫害之间关系变化。该过程涉及到植物有性繁殖体种子的产量。花期的变化会对农业粮食安全产生影响,同时植物的繁殖影响到自然生态系统植物群落组成的变化,进而影响到生产力。因此,该研究综述了近年来国内外植物花期对气候变化的影响,并在此基础上对未来的研究方向进行了探讨和展望。

Human-induced increasing of atmospheric greenhouse gas concentrations caused climate warming.Temperature shifted concomitance with changes in atmospheric water and heat,extreme weather events.Climate change not only caused by changes in plant flowering phenology,but also lead to changes in plant insect pests and insect-flowering.The process involved sexual propagules plant seed production.Thus,changes in flowering impacted on agriculture for food security.Meanwhile seed of plants to changes in natural ecosystems affected plant community composition and ecological function.Therefore,this paper reviewed the recent domestic plants flowering impacts of climate change and prospects.
