摘　　要：在地质背景和现今环境双重作用影响下，通过水载体，生命元素从岩石到土壤经农作物最后到人体流动过程中，不同介质内的含量、赋存形态及其转移方式等综合因素，决定了区域生物环境地球化学特点。由于生命元素分布不均和活度的差异影响了农业生产，并诱发了一些地方性疾病。根据生命元素的区域分布、有效性，水和土壤地球化学特征，使用好水、土资源，因地制宜，合理规划，促进农业持续发展，预防和控制生物环境地区化学疾病。“中国生态环境地球化学图集”和“区域地球化学与农业和健康”文集集中反映了上述成果。For application of environmental geochemisny to agricultUre and life science, we have cAned out a series of investigahons and experments, such as the investigation of elements in meals and malignant tUmors of inhabitants in whole China, measurement of radon concentration in typical areas, analyses of hydrogeochemical conditions for the formation of fluorine－－high groundwater in North China Plain and its mode of occurrence, the experimentation for the tyansformation and migration of selenitim indifferent ecological environments, and the test for the relationship betWeen traceelements in soil and growth of oranges.For above researches, 16 units affiliated tO three great departments , viz. Ministry of Land Resources, Ministry of Public Health and Chinese Academy of Sciences, have taken part in this hem of joint research worh which strides across differentdisciplines and several departmentS and involves fairly broad fields of sciences. Theresearches cover a series of subjectS, such as (1) the distribution characteristics of nutrihve elementS for creatures and human bodies in different geological and geochemical backgrounds and ecological geochemical systes, (2) the regionalhydrogeochemical characteristics of shallow grounduater; (3) the geochemical types,distribution, evolution and regional characteristics of the soils; (4) the spatial differentiation of effective content of elements in the soils, (5) the soil geochemical characterishcs of the subtropical zone and deserts and their significance in agricultUralproduction; (6) the geographical distribution of major endemic diseases in China and its relationship with vital elementS, (7) the intake quanhty of elementS by inhabitantsof whole China from food and its influence on human health, and (8) the relationship betWeen element content of hairs and mortality rares of major malignant tUmors.At the same bine, we collected, analysed and soded out various kinds of data,including 1;200 000 regional geochemical surveying data obtained from 29 provinces,municipalities d
