对地球化学的某些领域，如元素的丰度和起源；地球与太阳系的化学演化；资源的勘察、利用与成因研究；元素的循环与示踪；环境地球化学；天体化学；分析与实验地球化学等在20世纪所取得的进展作了简短回顾。并对地球化学的某些领域，如全球变化研究与生态环境保护、新的洁净能源与矿产资源、防灾减灾和保障人群健康、征服太阳系并使之为人类社会的可持续发展服务等方面的发展前景作了简要论述。

The authors, in this paper, briefly introduce and review the achievements in some research fields of geochemistry, particularly in the abundance and origin of the elements, the chemical evolution of the Earth and the Solar System, the reconnaissance, formation and utilization of resources, the circling and tracing of the elements, environmental geochemistry, space chemistry, analysis and experimental geochemistry, also demonstrate and prospect some key research fields of geochemistry such as global changes and the protections of the eco-environment, the new lustration energy and mine resources, the preventing and decreasing of the natural disasters, the guaranteeing of man’s health, and the overmastering of the Solar System for the sustainable development of  human society.
