The spatial distribution of heavy metal pollution in loess is an essential prerequisite and scientific basis for detecting and evaluating the quality of loess ecosystem and the sustainable development of regional environment, but lack of research in special soil such as loess. Distribution characteristics and pollution sources of heavy metals in the northern loess area of Baoji is studied by means of geo-statistics and cluster analysis. The results showed that heavy metal pollution still existed in this area, and the pollution in Changqing town was obviously higher than the surrounding area. Consequently, different management strategies can be adopted in the loess area to reduce the contamination load of heavy metal, and attention should be paid to human activities, such as mining, transportation and gas emission, especially.
