Based on regional geochemical investigation and the results of agricultural studies performed in the HangzhouJiaxing-Huzhou plain, a preliminary study of the agricultural geochemical regionalization for crops plantation and fertilization was carried out. The result shows that the area can be divided into four agricultural geoehemical regions as follows: (1 ) the geochemical region of provisions and oil crops and white mulberry of lagoon-lake-swamp, (2 ) the geochemical region of provisions crops,white mulberry...

Based on regional geochemical investigation and the results of agricultural studies performed in the HangzhouJiaxing-Huzhou plain, a preliminary study of the agricultural geochemical regionalization for crops plantation and fertilization was carried out. The result shows that the area can be divided into four agricultural geoehemical regions as follows: (1 ) the geochemical region of provisions and oil crops and white mulberry of lagoon-lake-swamp, (2 ) the geochemical region of provisions crops,white mulberry and oil crops of the network plain of rivers, (3 ) the geochemical region of fiber crops, cotton and vegetables of the littoral plain and (4) the geochemical region of teas,bamboos and woods of the low mountain sand hills. The fertilization plan of ten nutritive elements in this area was suggested and crops plantation and fertilization in each agricultural geochemical region was discussed. It is predicted that ecnomic benefits can be increased in agricultural production in this area by rational crops plantation and scientific application of fertilizer.

根据杭嘉湖平原区区域农业环境地球化学调查资料及在此基础上开展的区域农业、专题农业地球化学研究结果,对本区进行了农业地球化学区划的初步研究。研究结果将本区分为泻湖湖沼粮油桑地球化学区、水网平原粮桑油地球化学区、滨海平原麻棉菜地球化学区和低山丘陵菜竹林地球化学区,提出了本区10种营养元素施肥规划,阐述了每个地球化学区的作物布局、施肥方法,预测了据此结果可能给本区农业生产增加的经济效益。

Exploration geochemistry in Zhejiang province in recent forty years has underwent a long history from nonexistence to existence, from feebleness to strong, from single field to multi fields and from single objective of ore-seeking to multiple targets of servicing the whole society. Geochemical exploration was only regarded as an ore-seeking method in 1960s~1970s. The first regional geochemical investigation which started at 1963 had a purpose of general surveying and ore-seeking. The second regional geochemical...

Exploration geochemistry in Zhejiang province in recent forty years has underwent a long history from nonexistence to existence, from feebleness to strong, from single field to multi fields and from single objective of ore-seeking to multiple targets of servicing the whole society. Geochemical exploration was only regarded as an ore-seeking method in 1960s~1970s. The first regional geochemical investigation which started at 1963 had a purpose of general surveying and ore-seeking. The second regional geochemical investigation had made great break through in gold-finding during 1980~1994. From 1990s, environmental geochemistry, agricultural geochemistry and ecological geochemistry have been sprung up gradually, exploration geochemistry has entered developing period of multiple targets.

40多年来,浙江省勘查地球化学工作经历了从无到有,从弱到强,从单领域到多领域,从单一的地质找矿的目标到为全社会服务的多目标的历程。20世纪60~70年代,化探作为一种找矿手段。自1963年开始的第一代区域勘查地球化学调查,以普查找矿为目的。1980~1994年进行了第二轮区域化探扫面,在找金矿方面取得较大突破。90年代初起,我省环境地球化学、农业地球化学、生态地球化学逐渐兴起,勘查地球化学进入了一个崭新的多目标拓展时期。

The characteristics, objectives,principles and tasks of ecologicalgeochemical mapping have been elucidated in this paper according to information acquired abroad. The tasks of ecologicalgeochemical mapping include rational land use and regional programming, investigation of environmental geochemical baseline related to human health,prognosis of mineral resources and researches on agricultural geochemistry.

以国外资料为基础,较系统地论述了生态地球化学填图的特点、目标、原则和任务,指出了生态地球化学填图的未来发展趋势。生态地球化学填图的任务包括4个方面:土地合理利用和区域规划研究、环境地球化学基准调查及其与健康关系研究、矿产资源预测和农业地球化学研究。
