地外星体撞击引发的全球环境变化的巨大效应日益受到关注。植物作为敏感的环境指示,从植被组成和演替、类群分布和分化、形态和结构、细胞与分子生物学等不同层次上,对这种撞击引发的全球变化都应有所反映。从地学与生物学角度,协同研究撞击效应与植物演化的相互关系及相互作用的过程与规律,成为有关学科发展的前沿。
The tremendous effect of the global environmental change triggered by the alien collision has drawn increasing attention. Plants, as sensitive environmental indicators, should reflect the global changes triggered by such impacts at different levels of vegetation composition and succession, taxa distribution and differentiation, morphology and structure, and cellular and molecular biology. From the perspective of geosciences and biology, collaborative research on the relationship and interaction between impact effects and plant evolution and the process and law of interaction has become the frontier of discipline development.
