摘要:

地球表层是由山水林田湖草等要素构成的互动和互馈的复杂系统,这些要素中化学元素的互动和互馈过程均可驱动化学元素分布模式的变化。本文以系统的1∶25万土地质量地球化学调查数据为基础,讨论了中国西南地区土壤中常量元素、亲生物元素、卤族元素、重金属元素分布模式的驱动机制和互动过程。结果发现成土母质决定了土地资源中化学元素的自然状况,表生地球化学动力学过程重塑了表层土壤中元素分布模式,生物地球化学过程驱动了土地质量的演化趋势,强烈的人类活动(如矿业活动)破坏了元素分布的自然演化规律。表生地球化学动力学理论的提出将引领山水林田湖草生命共同体知识体系构建和土地资源地球化学综合调查技术的革新。

Abstract:

 The surface layer of the Earth is a complex system made of interacting and communicating components such as mountains, rivers, forests, farmlands, lakes, grasses, etc. The interaction and mutual feedback of chemical elements in Earths surface layer can drive changes in their distribution patterns. In this paper, we studied the driving mechanism and process of interaction of the distribution patterns of macroelements, probiotics, halogens, and heavy metals in soils in Southwest China based on a systematic land quality geochemical survey at scale 1∶250000. The results showed that the parent material determines the natural state of chemical elements in land resources; the epigenetic geochemical dynamics process reshapes the distribution patterns of chemical elements in surface soil; biogeochemical processes drive the evolution trends of land quality; and strong human activities, such as mining, disrupts the natural evolution of elemental distribution patterns. By establishing an epigenetic geochemical dynamics theory, one can construction a knowledge system for the Earths surface layer and promote technological innovation in comprehensive geochemical investigation of land resources.

Key words: epigenetic geochemical dynamics, driving mechanisms, distribution pattern of elements in soils, Southwest China
