土壤环境的变化在短时间内是缓慢且不易察觉的,但是在地球历史的演化中,它留下了一丝丝印迹,这就是古土壤。它包含了当时环境的大量信息,是5大成土因素的综合产物。当人类出现后,尤其是近百年来在复杂的自然因素上又叠加了人为作用,并且这种作用的强度与日俱增。当它对土壤的影响超过其它作用后,便形成了人为土壤,同时,也可能引起土壤退化和土壤污染。这些变化同全球变化和社会持续发展密切相关。
Environmental change of soils is an important component part of global change. The type of paleosols of China is diversified and has considerable difference in various regions. Environmental problem of soils is serious in the last 100 years and in future, which has directly impacts on the sustainable development of national economy in the 21st century. The present paper deals with historical evolution of soil mantle, change of soils in the last 100 years and the tendency of soil change in future. Environmental change of soils depends on natural factors and human activities and the latter plays more vital role with time. Of course, to study environmental change of soils acquires a deep understanding not only for the process of soil change, but also for the function of soil evolution. At the same time, it is necessary to estimate the status and quality of soil change, as well as its society, and to make a global or national strategy for harmony between soil environment and human activities.
