Environmental protection and sustainable development in agriculture has become key problems of human being in nowadays,and the heavy metal contaminates is one of severe pollutive originations,which enters the human body by food chain and endangers the health of human being. In this paper,the origination of heavy metal in soil was conducted and the review about the methods of heavy metal spacial variation in soil was discussed. The proposed implications were as follow:① the study on spacial variation of the heavy metal should be conducted by Geostatistical methods combinated with 3S technic;②a model about the geostatistics and the spacial variation of heavy metal was built.
