ABSTRACT
In this paper, we measured the soil resistivity of 178 typical cities where the substation is widely distributed in China, calculated the unmeasured area based on the Kriging method, and then, drew the soil resistivity map of spring and the seasonal variation coefficient. Meanwhile, we analyzed time–space characteristics of soil resistivity and the reasons. The results show that, from the seasonal point of view, the soil resistivities of most regions dropped to their minimum values during summer, while reached the maximum value during winter, but that of Urumqi are during spring and summer. The months during which different soil resistivities reach the maximum and the minimum are not the same. From the regional point of view, soil resistivity in Northwest China is on the high side, and its seasonal change is obvious, but the situation in most parts of Central China and Eastern China is just on the contrary.
