文摘 地表过程对全球变化的响应和反馈是地球系统科学研究的核心课题之一,目前的研究多关注全球变化对地表过程的影响,而地表动态过程对地表生物物理过程及气候的反馈研究较少。系统认识地表物候动态对生物物理过程及气候的反馈对深化地球系统科学研究有着重要的意义。本文从农业物候动态的事实、农业物候动态在陆面过程模型中的参数化表达、农业物候动态对地表生物物理过程及气候的反馈等方面进行综述,发现在气候变化和管理措施影响下,以种植期和灌浆期为代表的农业物候期发生了显著的规律性变化;耦合农业物候动态,改善了模型对地表动态过程、生物物理过程和大气过程的数字化表达;农业物候变化对地表净辐射、潜热、感热、反照率和气温、降水、环流等过程产生了影响,并表现出以地表能量分配为主的气候反馈机理。针对农业物候动态对地表生物物理过程及气候效应的时空重要性,需要继续开展以下方面的工作:①加强全球变化对地表物候动态的影响及其反馈的综合研究;②不同光谱波段地表反射率与农业物候动态的关系研究;③农业物候动态引起的作物生理学特征变化在地表生物物理过程中的贡献;④重视不同气候区物候动态对气候反馈效应的差异。
其他语种文摘 The response and feedback of land surface processes to climate change constitute a research priority in the field of geosciences. Previous studies have focused on the impacts of global climate change on land surface processes; however, the feedback of land surface processes to climate change remains unknown. It has become increasingly meaningful under the framework of Earth system science to understand systematically the relationships between agricultural phenology dynamics and biophysical processes, as well as their feedback to climate change. This study summarized research progress in this field, including agricultural phenology change, parameterization of phenology dynamics in land surface process models, and the influence of agricultural phenology dynamics on biophysical processes, as well as its feedback to climate. The results showed that the agricultural phenophase, represented by paramount phenological phases such as sowing, flowering, and maturity, has shifted significantly because of the impacts of climate change and agronomic management. Digital expressions of dynamic land surface processes, as well as biophysical and atmospheric processes, have been improved by coupling phenology dynamics in land surface models. Agricultural phenology dynamics influence net radiation, latent heat, sensible heat, the albedo, temperature, precipitation, and circulation, thus, play an important role in surface energy partitioning and climate feedback. Considering the importance of agricultural phenology dynamics in land surface biophysical processes and climate feedback, the following research priorities have been identified: (1)interactions between climate change and land surface phenology dynamics, (2)relationships between agricultural phenology dynamics and different land surface reflectivity spectra, (3)contributions of changes in crop physiological characteristics to land surface biophysical processes, and (4)regional differences of climate feedback from phenology dynamics in different climatic zones. This review will be helpful in accelerating the understanding of the role of agricultural phenology dynamics in land surface processes and climate feedback.
