With the continuous improvement of people’s living standards, people’s requirements for environmental quality are also getting higher and higher. Soil environmental quality is an important component of environmental quality. Soil environmental quality is related to people’s living, diet and life safety. In this paper, the factors affecting soil environmental quality in Beijing were studied by using grey relational theory. In the order of importance from big to small,these factors are as follows: total energy consumption, gross domestic product, input level of science and technology, fertilizer use and environmental protection input level. Based on the above analysis, the corresponding countermeasures are put forward.
