Abstract: According to field investigation and data measured by elect-chemistry methods,the paper studies the distribution regularity of different factors in native environments,such as soil,food and drinking water,in Jilin province of China.The results show that Mo content in food and water progressively is reduced from the west part to the east part of this province,and whole Mo and effective Mo contents in soil in the eastern mountains are higher than that in the western plain and terraice area,even then the effective Mo content in soil in a great of area is lower than normal content, therefore it can’t well satisfy growing need of grain crops.In the east mountains the content of Mo in aqueous solution in soil is lower than that in the west part.The paper expounds the regional division of biogeochemistry for microelement of native environment,and gives the regional division map for Mo.Based on Mo content absorbed by human body,Mo contribution in native environment can be divided into two areas,the western plainterraince area with higher Mo content in water and food and the eastern mountaineous area with lowet Mo content in water and food,and 5 subareas.This division is significant for studing environment and health,and factors causing local desease,and for developing agricultural production and environmental protection.
