摘要
科学家早就注意到,植物物候作为气候变化对生态影响的感应器,具有敏感、易于监测和理解的特点,是植被生产力与植被动态模拟的重要参数。全球变化引起植物生长节律的变化,许多地区春季植物物候提前,秋季物候推迟,生长季延长,使得植物间竞争与依赖关系也发生深刻改变。作者从植物物候的概况、全球变化下植物物候的响应等方面,综合论述了植物物候的研究进展,探讨了中国植物物候在全球变化下的响应变化,提出植物物候研究未来的发展趋势。
Plant phenology directly reflects the effects of climate change. With the development of remote sensing and modeling techniques, the relationships between plant phenology and global climate change have been increasingly attracting scientists＇ attention. The changes in rhythm of plant growth may alter plant - environment relationships, and influence 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 have showed that the plant phenology appear earlier in spring and disappear later in autumn. The changes in plant phenology result in a lengthening growing season. From the aspects of environmental factors, the responses of plant phenology to global change, and the remote sensing monitoring of plant phenology, this paper reviews the research advances in plant phenology research, and predicts the trend for future research .
