化学地理研究的回顾，近期进展和瞻望

RETROSPECT, CURRENT DEVELOPMENT,AND PROSPECT OF CHEMICAL GEOGRAPHY RESEARCH

本文回顾了化学地理半个多世纪以来发展的三个阶段，特别是６０年代后中国化学地理在研究环境保护和地方病病因及其防治方面的进展，并讨论了化学地理今后研究的方向。

The present article tries to identify and evaluate the major academic contributions to chemical grography in recent years. This paper is outlined in four parts:1. A brief history of chemical geography: (1) During 30-50s', it was the period for the birth of chemical geography, initiation of the theory of landscape geochemistry, and data accumulation. (2) During 50-60s', chemical geography was developed and was enlarged, and the theory system was formed and established. (3) After 60s', chemical geography in our country has entered upon the rapid development periold.2. Research works in chemical geography have made progress in medicine (endemic diseases) in China as follows: the correlative law of elemental composition of organism with elemental composition of grochemical environment; the geochemicl-ecological classification of chemical elements; the type of formative cause of biogeochemical provinces in China; the parabolic correlation between contents of iodine in drinking water and prevalence rate of endemic goiter; succesive exposition and proof of low selenium zone of Keshan and Kaschin-Beck in China; the compilation of the Atlas of Endemic Diseases and Their Environments in the People's Republic of China.3. Research works on chemical geography have made advances in environmental protection.The main areas of the research were the following: investigation of environmental pollution in some large rivers, lakes, and large cities area (including surounding area), their environmental quality assessment, and comprehensive control; study on the behavior and state of toxic and hazadous substances in the pollutants in air, water, soil and biological materials;study on invironmental background values and environmental capacities of soil and water bodies in China; research on trace elements including REE pollution in agricultural area.4. Prospects for chemical geography in China are briefly discussed.
